The 50 most-cited articles in Veterinary Record, 2020

BACKGROUND: Pet owners have many feeding options, some may be considered unconventional by veterinary practitioners. Provision of appropriate nutrition is a basic requirement, with adverse health outcomes possible when a pet diet is inadequate. OBJECTIVE: To capture dog and cat feeding practices, with a special focus on countries with large English-speaking populations, and to compare with data published over the previous 10 years. METHODS: An electronic questionnaire was provided for dog and cat owners online. Responses were analysed using descriptive statistics, and comparisons made with data from nine peer-reviewed articles published over the previous 10 years. RESULTS: Responses from 3673 English-speaking dog and cat owners in Australia, Canada, New Zealand, the UK and the USA were included. In previous publications, conventional (commercial, heat-processed) products were the predominant method of feeding. In recent publications, feeding unconventional (raw, homemade, vegetarian) diets appeared more prevalent. In the present study, most (79 per cent dogs, 90 per cent cats) pets…

BACKGROUND: Recruitment and retention is currently of major concern and has resulted in the veterinary profession being returned to the UK's Shortage Occupation List in 2019. METHODS: An online questionnaire of veterinary employees and employers investigating factors contributing to leaving/staying in current employment and the profession. The questionnaire was distributed via specialist veterinary associations' email lists and social media from September to October 2018. RESULTS: Respondents had few job changes (median 3), however, 43.7 per cent (n=2390) reported that they were likely or very likely to leave their employment within two years. Vets who were recently qualified, on lower salaries and female were more likely to plan to leave. Most frequently chosen reasons to stay in a position were: team, location and family. Most commonly cited reasons to leave were: work-life balance, management and salary. Respondents most disliked dealing with people, work-life balance and the physical/emotional impacts of the job. They would most like to change the hours worked, team aspects and…

BACKGROUND: Higher rates of depression, suicidal ideation and suicide risk have been reported for veterinarians in various studies worldwide. This study investigates whether this is also true for German veterinarians. METHODS: A total of 3.118 veterinarians (78.8 per cent female, mean age 41.3 years) between 22 and 69 years were included and compared with two general population samples of the same age range using the Suicide Behaviours Questionnaire-Revised and Patient Health Questionnaire. RESULTS: Current suicidal ideation was found in 19.2 per cent of veterinarians, compared with only 5.7 per cent in the general population. 32.11 per cent of veterinarians were classified with increased suicide risk, compared with 6.62 per cent in the general population. 27.78 per cent of veterinarians screened positive for depression, compared with 3.99 per cent of the general population. CONCLUSION: The study shows that veterinarians have an increased risk of depression and suicidal ideation and suicide risk compared with the general population in Germany. Similar to previous findings, the level…

BACKGROUND: The welfare of all animals under human management is an area of consistent public concern, but strategies to improve welfare may vary across species. In this study, expert consensus, using a modified Delphi approach, was used to prioritise welfare issues of farmed and companion animals in the UK. METHODS: The study involved 117 experts, divided between eight species groups. Experts were recruited from a broad range of disciplines. Two rounds of online surveys were conducted using the online survey tool, and the final round was an in-person workshop with a subsection of experts (n=21). The experts agreed that welfare issues should be ranked considering three categories: (1) severity, (2) duration and (3) perceived prevalence. RESULTS: A comprehensive list of welfare issues was generated for each species by discussion boards (cats, rabbits and horses) or by literature review (dogs, pigs, poultry, cattle and small ruminants). In the first online survey, the experts scored each welfare issue using the three categories (severity, duration and prevalence) on a 6-point Likert…

Background Rescuing dogs from overseas is increasing in popularity but has associated risks. This study is the first to investigate the reasons why people bring rescue dogs into the UK from overseas, the importation process, and potential welfare problems associated with this practice. Methods An online questionnaire was advertised on social media in 2017 and received 3080 responses. Results Participants primarily chose to adopt from abroad based on a desire for a particular dog they had seen advertised and on concern for its situation. However, some were motivated by previously having been refused dogs from UK rescues. Adopters reported that the EU Pet Travel Scheme was used to import 89 per cent of dogs, with only 1.2 per cent reportedly under the more stringent (and correct) Balai Directive. 14.8 per cent (79/533) of dogs reportedly tested for Leishmania infantum had positive results. Although sometimes severe, the prevalence of behavioural problems appeared comparable to that of other rescue dogs. Conclusion It is important that vets consider testing for exotic diseases, and the…

Background Feeding dogs with raw meat‐based diets (RMBD) has increased in popularity in recent years. Proponents claim that RMBD is more natural for dogs, because it is what their ancestors (wolves) eat. Opponents claim that RMBD is a health hazard to both humans and animals, with a risk of spreading zoonotic bacteria and resistant bacterial strains. Methods This cross‐sectional study investigated differences in bacteria shedding in faeces between dogs fed RMBD and dogs fed dry kibble. Faeces samples from 50 dogs from the same municipality were analysed for the presence of extended‐spectrum beta‐lactamases (ESBL)‐producing Escherichia coli , Campylobacter and Salmonella . Results For the 25 dogs fed RMBD, ESBL E coli was isolated from 13 faeces samples, Campylobacter from 12 and Salmonella from 1. For the 25 dogs fed dry kibble, ESBL‐producing E coli was isolated from one faeces sample and Campylobacter from four, while Salmonella was not detected. Conclusion There was thus a significant difference in excretion of zoonotic and resistant bacteria in faeces between dogs fed RMBD and…

BACKGROUND: Acute paralysis is a common presentation in small animal emergency clinics, but the aetiological prevalence has not been reported. Knowledge of diagnosis frequency aids prioritisation of differential diagnoses, facilitates resource planning and clinical trial design. METHODS: Medical records from NC State Veterinary Hospital Emergency Room were searched over a five-year period to identify cases presenting with acute non-ambulatory paraparesis or paralysis. Signalment and diagnosis category were extracted. RESULTS: Acute paralysis was the presenting problem in 845 of 21,535 (3.9 per cent) dogs and 66 of 4589 (1.4 per cent) cats admitted over this period. Intervertebral disc disease (IVDD) was the most common cause (608 of 845; 72 per cent) in dogs, followed by vascular disease (34 of 845; 4.0 per cent). Other diagnostic categories accounted for the remaining 20 per cent. Dachshunds were the most common breed (263 of 845; 31.1 per cent), then Labrador retrievers (57 of 845; 6.7 per cent). In cats, aortic thromboembolism (ATE) was the most common diagnosis, occurring in 40…

BACKGROUND: Communication skills to promote changes in management routines are especially important in veterinary herd health management (VHHM). Motivational interviewing (MI) is a communication methodology shown to be effective in stimulating client behaviour change. This study aimed to evaluate a 6-month MI-training programme for veterinarians. METHODS: Thirty-eight cattle veterinarians gathered in groups of four to eight at six workshops separated by 3-4 weeks, during which they read literature and practised their skills. MI skills were evaluated before and after training using audio recordings of role-play conversations with professional actors. Recordings were coded using the MI Treatment Integrity Code (MITI) V.4.2.1. The effect of training was evaluated by 16 regression models. Participants filled in questionnaires about their experiences. RESULTS: All participants improved their MI skills after training in at least one parameter and significant improvements were found in all but 3 of the 16 statistically evaluated MITI variables. The mean (25th-75th percentiles) ratings of…

BACKGROUND: The objectives of this study were to establish the prevalence, risk factors and comorbidities/sequelae for diabetes mellitus (DM) in Australian dogs presented to first-opinion veterinary practices. METHODS: Electronic patient records of dogs (n=134,329) attending 152 veterinary clinics during 2017 were sourced through VetCompass Australia. They included 418 dogs with DM; a prevalence of 0.36 per cent (95 per cent CI 0.33 per cent to 0.39 per cent) in Australian dogs attending these veterinary clinics. By comparing with the reference group of rarer breeds and unidentified crossbreeds, multivariable modelling was used to reveal breeds (and their crosses) with significantly higher odds of having DM. RESULTS: The results revealed that breeds (and their crosses) with significantly higher odds of having DM were Australian terriers (ORs=7.93 (95 per cent CI 2.83 to 22.27)), Siberian huskies (OR=6.24 (95 per cent CI 2.51 to 15.54)), English springer spaniels (OR=5.37 (95 per cent CI 1.48 to 19.53)), West Highland white terriers (OR=4.85 (95 per cent CI 2.55 to 9.25)), miniature…

Background The aim of the present study was to investigate the effects of Lactobacillus acidophilus D2/CSL (CECT 4529) probiotic strain on nutritional status and faecal and microbiological parameters in a group of purebred boxers. Methods Forty healthy adult boxer dogs were randomly assigned to a treated (LACTO) group receiving a commercial diet supplemented with L acidophilus D2/CSL (CECT 4529) to a final concentration of 5.0 x 10 9 colony‐forming unit/kg of food, and a control (CTR) group receiving the same diet but without the probiotic (placebo). Nutritional status (body weight, skinfold thickness, body condition score) and faecal quality parameters were analysed. Results No differences in body weight and skin thickness were found during the whole experimental period. Dogs in the LACTO group showed a significantly higher body condition score than those in the CTR group (4.86±0.55 v 4.65±0.65), and no significant differences were recorded in body weight and skinfold thickness. The LACTO group showed a significantly lower faecal moisture (in per cent) compared with the CTR group…

Following previous reports of Covid-19 infection in two dogs in Hong Kong earlier in February and March,1-4 further test results have been released by the Government of the Hong Kong Special Administrative Region (GHKSAR), changing the serology interpretation previously reported (VR, 28 March 2020, vol 186, pp 388–389).3, 5 Despite several positive RT-PCR results suggesting a true infection in a Pomeranian dog, the dog had initially tested negative for antibodies specific to Covid-19 on a blood sample taken on 3 March 2020. Further serological testing of this sample at the WHO reference laboratory at the University of Hong Kong (HKU) was reported positive in late March.5 Antibody formation can take 14 days or more before it can be detected and this lag could explain why antibodies were not identified initially. However, a weak infection where antibodies do not develop is sometimes seen with other coronavirus infections in people. The consensus remains at this time that there is no evidence that infected pets are a source of infection for people or other pets As mentioned in my…

BACKGROUND: Little research has been carried out into how guinea pigs are cared for in the UK, and information regarding potential welfare issues is sparse. This study was designed to examine the five welfare needs, collecting data on the extent to which these are each met by a sample of UK guinea pig owners. METHODS: A survey of 4590 owners was conducted. RESULTS: Guinea pigs were housed in a variety of ways, but a hutch or cage, with no attached run, was the most common enclosure. The majority reportedly lived with a conspecific, although some lived on their own, or with a rabbit. Significant associations between aspects of housing and husbandry, and behaviour and health were found, for example, the frequency of positive behaviours displayed was higher in those guinea pigs housed with a conspecific and those in larger enclosures, while the number of reported health issues was lower in animals receiving green vegetables more often. CONCLUSION: This study has identified common practices, and highlighted some potential welfare issues, which would benefit from further research. The…

BACKGROUND: Virtual reality (VR) applications are effective tools in many educational disciplines. A minimally interactive VR application allowing stereoscopic viewing of surgical videos has been developed to aid veterinary students learning to perform surgery. We sought to describe how students used the VR application while preparing to perform their first canine sterilisation surgery and compare surgical performance of students who prepared using traditional methods with students who also used VR. METHODS: Third-year veterinary students (n=44) were randomised into control and VR groups in a parallel superiority randomised controlled trial. All were given lectures, videos and skills practice on models. VR group students were also given a VR application and headset to view stereoscopic surgical videos. Blinded raters scored a subset of students (n=19) as they performed their first canine ovariohysterectomy. RESULTS AND CONCLUSIONS: Groups spent similar time preparing to perform surgery, potentially because of the rigour of students' non-surgical course load. When VR training was…

BACKGROUND: Impostor syndrome (IS) is the tendency to doubt one's abilities despite positive evidence to the contrary. Individuals with IS are afraid of being discovered as intellectual frauds and attribute their successes to external qualities. METHODS: An international study explored the prevalence and severity of IS in practicing veterinarians. An anonymous survey consisting of the 20-question Clance Impostor Phenomenon Scale, plus additional demographic and work-related questions, was distributed online. RESULTS: A total of 941 practicing veterinarians responded. Overall, 631 participants (68 per cent) met or exceeded the clinical cut-off score for IS. Ordinal regressions found that residing in New Zealand (NZ) or the UK, being female or having been in practice for less than five years increased the odds of having a high IS score. The effect of these factors on the perceived degree of impact of IS on participants' professional and personal life was also explored. Women, UK residents and new practitioners reported higher levels of impact in their professional life. However, sex…

Introduction Respiratory diseases account for the highest number of clinical problems in horses compared with other body systems. While microbiological culture and sensitivity testing is essential for certain cases, knowledge of the most likely bacterial agents and their susceptibilities is necessary to inform empirical antibiotic choices. Methods A retrospective study of microbiological and cytological results from upper and lower respiratory samples (n=615) processed in a commercial laboratory between 2002 and 2012 was carried out. A further study of lower respiratory samples from horses with clinical signs of lower respiratory disease from May to June 2012 was undertaken. Results Both studies revealed Streptococcus equi subspecies zooepidemicus , Pseudomonas aeruginosa , Pasteurella species, Escherichia coli and Bordetella bronchiseptica as the most frequently isolated species. S equi subspecies zooepidemicus and subspecies equi were susceptible to ceftiofur (100 per cent) and erythromycin (99 per cent). Resistance to penicillin (12.5 per cent of S equi subspecies equi from upper…

Due to variation in study designs the prevalence of idiopathic epilepsy (IE) and structural epilepsy (SE) in dogs is largely unknown. The objective was to provide estimates of the prevalence of IE and SE in a large population of dogs undergoing MRI for epileptic seizures. A retrospective study on 900 dogs undergoing MRI for seizures was performed. MRI scans, summary clinical history and neurological examination from the VetCT database were reviewed and a diagnosis assigned by board-certified radiologists. Structural lesions were identified as a cause of seizures in 45.1 per cent (n=406) of cases. No structural lesions were identified in 54.9 per cent (n=494) of cases with presumed IE diagnosed in 53.8 per cent (n=484) of dogs. Dogs between six months and six years were more often associated with IE (P<0.001), small breeds were overrepresented with suspected inflammatory brain disease (P=0.001) and large entire dogs more often diagnosed with extra-axial neoplasms (P=0.001). Over 31.0 per cent of dogs with suspected IE were six years or older. This study is the largest of its kind in…

BACKGROUND: While euthanasia is a common feature of veterinary practice, research has yet to adequately explore the experiences, perception and wishes of pet owners, including their satisfaction and grief following companion animal euthanasia. METHODS: An online questionnaire was conducted with pet owners who had experienced euthanasia within the last 10 years to explore the relationship between pet owners' experiences and their resulting satisfaction and grief following companion animal euthanasia. Data were analysed using descriptive statistics and multivariable linear regression. RESULTS: Overall, participants (N=2354) reported high levels of satisfaction with their euthanasia experience. Their experience with the administration practices (i.e., payment and paperwork), emotional support, follow-up care and care for their pet's remains was found to be associated with overall satisfaction. Participants' grief was associated with the number of euthanasia previously experienced, the type of human-animal bond, if the euthanasia was emergent and the emotional support they received.…

BACKGROUND: In the last 20 years, two studies on the veterinary use of perioperative analgesia in small mammals reported a limited use of analgesics in rabbits but suggested an increasing use over the years. The aim of this study was to better understand how pain is treated and ameliorated in rabbits while under veterinary care. METHODS: An online survey of 60 questions was developed and advertised at national and international veterinary conferences, in veterinary publications and on social media. RESULTS: In total 94.3 per cent of the respondents routinely administered nonsteroidal anti-inflammatory drugs (NSAIDs) to rabbits undergoing surgical procedures such as neutering, 71.4 per cent administered an opioid and 70.3 per cent routinely administered multimodal analgesia, although dosages do not always match current consensus opinion. Buprenorphine and meloxicam were the most common analgesic drugs prescribed by the respondents. The dosage of meloxicam administered both parenterally and orally varied widely. CONCLUSION: Rabbit analgesia has improved over recent years similarly to…

BACKGROUND: ) populations are increasing worldwide and invading urban areas. Live-capture can improve the management of this challenge, maximising efficiency, allowing scientific studies and potentially improving animal welfare. This study assesses teleanaesthesia, drop-net, corral trap and cage trap to live-capture wild boar in urban and peri-urban areas, evaluating efficiency and animal stress through haematology and serum biochemistry. METHODS: From 2012 to 2018, 655 wild boars were captured in 279 operations (drop-net=17, teleanaesthesia=186, cage trap=66 and corral trap=10) in the urban and peri-urban areas of Barcelona (Spain). Haematological and serum biochemical variables were determined in 145 wild boars (42 drop-netted, 41 teleanaesthetised, 38 cage-trapped and 24 corral-trapped). RESULTS: Performance (wild boars captured per operation) was highest for drop-net, followed by corral and cage traps, and finally teleanaesthesia. The three physical capture methods were more stressful than teleanaesthesia, causing a more intense physiological reaction, muscular damage, renal…

BACKGROUND: Cefovecin is a long-acting third-generation cephalosporin commonly used in veterinary medicine. Third-generation cephalosporins are critically important antimicrobials that should only be used after culture and susceptibility testing. The authors describe the common indications for cefovecin use in dogs and cats, and the frequency of culture and susceptibility testing. MATERIALS AND METHODS: A cross-sectional study was performed using clinical records extracted from VetCompass Australia. A previously described method was used to identify records containing cefovecin. The reason for cefovecin use was annotated in situ in each consultation text. RESULTS: Over a six-month period (February and September 2018), 5180 (0.4 per cent) consultations involved cefovecin administration, of which 151 were excluded. Cats were administered cefovecin more frequently than dogs (1.9 per cent of cat consultations and 0.1 per cent of dog consultations). The most common reasons for cefovecin administration to cats were cat fight injuries and abscesses (28 per cent) and dermatitis (13 per…

BACKGROUND: Biologically appropriate raw food (BARF) diet is becoming more and more popular among pet owners in Europe. However, there are documented microbiological risks associated with raw feeding, and this study aimed to determine the presence of human pathogens in commercially frozen BARF products sold in Italy. METHODS: species were identified. The general microbiological quality of BARF products and hygiene were also evaluated. Sample size was limited and therefore the study may not be representative of a larger sample. RESULTS: None of the tested samples showed total bacterial count (TBC) higher than the limit set to consider a sample unacceptable. However, 14 out of 21 samples showed TBC higher than the limit set to consider a sample marginally acceptable. A high percentage of samples were contaminated by the aforementioned pathogens, highlighting the need for pet owners to be aware of the risks of this feeding strategy both to themselves and to their pets. CONCLUSIONS: Considering that BARF diet meals can be prepared at home using the hands, as well as tools and spaces…

BACKGROUND: Despite appropriate antiseizure drug (ASD) treatment, around two-thirds of dogs with idiopathic epilepsy (IE) have seizures long-term and 20-30per cent of affected dogs remain poorly controlled. METHODS: The current study aim is to test in a field trial the efficacy and tolerability of a commercially available diet enriched with 6.5per cent medium chain triglyceride (MCT) oil in dogs (n=21) with at least a tier 1 idiopathic epilepsy diagnosis, without cluster seizures, in 10 veterinary practices across Europe. Each dog's quality of life (QoL), ataxia, sedation and frequency and severity of seizures were recorded by owners throughout the study. RESULTS: The mean seizure frequency per month, averaged over the entire 84-day study, significantly (P=0.04) decreased 32per cent compared with the baseline monthly seizure frequency recorded during the month immediately before feeding the diet. Similarly, the seizure days rate (days/month) also declined (P<0.001) by 42per cent. QoL was reported as very good to excellent (>8.5/10) in 20 of the 21 dogs before starting the diet and…

Recently, two cats from Belgium and Hong Kong tested positive for SARS-CoV-2.1, 2 During the 2003 SARS-CoV outbreak, cats living in close contact with people with SARS were found to be positive for SARS-CoV.3, 4 The susceptibility of domestic cats (Felis domesticus) to SARS-CoV infection was then studied.4, 5 Experimental inoculations resulted in infection and viral shedding, although without clinical signs. The infected cats were also found to transmit the disease to susceptible animals living in close contact with them.4 The pathological changes induced by the experimental inoculation of SARS-CoV in cats were similar to those found in people except for the absence of syncytia and hyaline membranes in infected cells.5 In the current coronavirus outbreak, researchers at the Harbin Veterinary Research Institute in China found that experimental inoculation of SARS-CoV-2 in cats resulted in infection without clinical signs of illness. Infected cats also transmitted the virus to other cats that were in close contact via respiratory droplets,6, 7 although the transmission potential might…

BACKGROUND: Aim of the present study was to investigate the implementation of a targeted therapy (tLCT) concept under real-life circumstances, taking both pathogen-related and animal-related factors into account. The reduction of antibiotics without negative effects on cure rates was evaluated as well as the compliance by the farmers. METHODS: After analysing the existing conventional therapy (CT) concepts of five farms, the tLCT concept and a novel on-farm test were introduced. Three treatment groups were compared with respect to bacteriological cure (BC), cytological cure (CYC), full cure (FC), new infection rate (NIR), relapse rate and the treatment approach per mastitis case: the CT group, the tLCT group including all clinical mastitis (CM) cases treated according to the concept, and the modified tLCT group (tLCTmod), including the CM cases in which farmers deviated from the concept. RESULTS: Even so farmers deviated from the treatment concept in 506 out of 909 cases; belonging to one of the three treatment groups had no significant impact on BC, CYC, FC, NIR or relapse rate.…

BACKGROUND: The aims of this study were to assess the impact of epidemiological variables, severity of presurgical respiratory signs, diagnostic findings from pharyngeal and laryngeal examination using a new grading scheme and CT scan images, on postsurgical outcome in dogs undergoing surgery for brachycephalic obstruction airway syndrome (BOAS). METHODS: An owner-based questionnaire was used to grade dogs based on their respiratory signs before surgery and at least six weeks after surgery. Epidemiological data and results from presurgical pharyngeal and laryngeal examination and CT scan findings for 75 dogs undergoing airway surgery were collected from the medical records. RESULTS: 70.7 per cent of dogs showed an improvement in respiratory signs following rhinoplasty and palatoplasty. This improvement was associated with the severity of inspiratory efforts and the Poncet score on presentation, but not with any other clinical sign or anatomical abnormality found during BOAS assessment, nor by the degree of craniofacial shortening as determined by CT-scan. Presurgical snoring was…

BACKGROUND: This study aimed to describe the presentation and outcomes of horses with signs of colic (abdominal pain) seen 'out-of-hours' in equine practice. METHODS: This was a retrospective study of horses seen 'out-of-hours' with colic by two equine veterinary practices between 2011 and 2013. Case outcomes were categorised as 'critical' or 'not critical'. A critical outcome was defined as requiring medical or surgical hospital treatment, or resulting in euthanasia or death. A non-critical outcome was defined as resolving with simple medical treatment. A hierarchical generalised linear model was used to identify 'red flag' parameters (aspects of signalment, history and presenting clinical signs) associated with critical outcomes. RESULTS: Data were retrieved from 941 cases that presented with colic; 23.9 per cent (n=225/941) were critical. Variables significantly associated with the likelihood of a critical outcome in the final multivariable model were increased heart rate (P<0.001), age of the horse (P=0.013) and abnormal mucous membrane colour (P<0.001). Overall 18 per cent…

BACKGROUND: The continued growth of the global Halal meat market has resulted in many mainstream businesses in the developed world trading in Halal products. A good understanding of Halal consumer behaviour with regard to their preference of meat according to the method of slaughter (pre-stunned or not) and the frequency of consumption is vital for the formulation of future animal welfare legislation, consumer protection policies and research strategies of educational institutions. METHODS: In this study, 250 Halal meat consumers in England were surveyed to obtain a better understanding of their meat consumption frequency, preference of meat according to species of animals and the method of slaughter. RESULTS: The results show that the majority (50.8 per cent) of consumers ate meat at least once a week, 45.6 per cent at least once a day, 3.2 per cent at least once a month and 0.4 per cent ate meat occasionally. Poultry meat was marginally the most preferred meat among respondents overall, followed by lamb and beef, with the majority of respondents (approximately 70 per cent)…

BACKGROUND: Across Asia the brick-kiln industry is expanding. In Nepal, urban dwelling has increased in recent years, raising requirement for low-cost, mass produced bricks to meet the population needs. Working equids (WEs) play a key role in non-mechanised kilns. Assessing the welfare of these equids is the starting point to addressing concerns. In line with One Welfare principles, the health and welfare of animals, people and the kiln environment are interlinked. MATERIALS AND METHODS: In December 2019, 119 WEs were assessed in seven brick kilns in three districts of Nepal, using the Equid Assessment Research and Scoping tool, developed by The Donkey Sanctuary. The objective was to measure welfare at the start of the brick kiln season. RESULTS: Horses were the predominant species of WE. Hazardous housing and environments were seen in all kilns. Behaviour responses were mixed. Owner responses and animal examination indicated poor working conditions. Signs of harmful practice were evident in most animals. The majority were underweight, with poor general health, skin alterations and…

BACKGROUND: Abnormalities of the ventral lamina of the sixth cervical vertebra (AVL-C6) are thought to exert abnormal stress on the articular process joints (APJs) of the cervicothoracic junction. The aim of the study was to investigate the association between AVL-C6 and radiographic findings in the caudal cervical area and between clinical signs of neck pain and ataxia and radiographic findings. METHODS: Medical records of horses subjected to cervical radiography were reviewed. Horses were classified into those with neck pain (group C), those with ataxia (group A) and healthy horses (group H). Presence of AVL-C6 and increased size, dysplasia, remodelling, fragmentation and osteochondral fragment at the APJs (C5-T1) were recorded. Univariable logistic regression analysis was performed to identify the associations between explanatory and dependent variables. Variables with P<0.2 were included in the multivariable analysis. RESULTS: One hundred and sixteen horses were included (44 in group C, 29 in group A, 66 in group H); 24 of 116 horses had radiographic AVL-C6. Age, AVL-C6 and…

BACKGROUND: This paper explores the current role and place of diagnostic tests in the treatment of farm animal disease. With the growing focus on reduced reliance on antibiotic medicines in both animal and human patient care, attention is increasingly being focused on the practice, the technology and the function of diagnostic tests and how these can support responsible antimicrobial use. Emerging diagnostic technologies offer the possibility of more rapid testing for bacterial disease, while food chain actors and others are increasingly seeking to make diagnostic tests mandatory before the use of critically important antibiotics. METHOD: This paper reports the findings of a recent large-scale online survey of UK farm animal veterinarians (n=153) which investigated current veterinary diagnostic practice with particular attention to the relationship between diagnostic test use and antibiotic treatment. RESULTS: Results revealed a range of factors that influence veterinary diagnostic practice and demonstrate the continuing importance of clinical observation and animal/herd knowledge…

BACKGROUND: Near-infrared fluorescence (NIRF) imaging is a relatively novel technique that can aid surgeons during intraoperative tumour identification. METHODS: Nine canine oncology patients (five mammary gland tumours, three mast cell tumours and one melanoma) received intravenous indocyanine green (ICG). After 24 hours, tumours were resected and fluorescence intensities of tumours and surroundings were evaluated. Additional wound bed tissue was resected if residual fluorescence was present after tumour resection. Ex vivo, fluorescence-guided dissection was performed to separate tumour from surrounding tissue. RESULTS: Intraoperative NIRF-guided tumour delineation was feasible in four out of nine dogs. Wound bed imaging after tumour removal identified nine additional fluorescent lesions, of which four contained tumour tissue. One of these four true positive in vivo lesions was missed by standard-of-care inspection. Ex vivo fluorescence-guided tumour dissection showed a sensitivity of 72 per cent and a specificity of 80 per cent in discriminating between tumour and surrounding…

BACKGROUND: A large number of snakes are kept as pets in Western societies. Few studies have been undertaken to assess keeping practices of snakes by private owners in Australia. Therefore, there is concern that some owners may not understand even basic husbandry requirements. The aim of this preliminary study was to identify the most common practices used by snake owners in Victoria, Australia. METHOD: An online survey asked 251 snake owners to describe ways in which they attempt to meet their snake's environmental, behavioural, dietary, social and health needs. RESULTS: Fewer than half of participants had an enclosure large enough for the snake to fully stretch out, and just over half had an enclosure large enough to meet the requirements in the Victorian Code of Practice. Only 60 per cent of owners correctly identified their snake's activity patterns based on information about wild snakes of the same species. CONCLUSION: Educational campaigns may help improve outcomes for snakes in the future, but more research is needed about captive snake husbandry, to provide an evidence base…

BACKGROUND: -associated diseases (CDAD) is considered to be associated with colitis in horses, few studies have been performed with a focus on the characteristics of CDAD in thoroughbred racehorses. METHODS: was performed using faecal samples from 137 thoroughbred racehorses with colitis presenting with diarrhoea and fever. The mortality rate, clinical findings, predisposing factors and the selected treatments were investigated in a retrospective manner. RESULTS: Twenty-four cases were diagnosed as CDAD and 113 as non-CDAD. The mortality rate was significantly higher in the CDAD group (83 per cent) than that in the non-CDAD group (34 per cent). The levels of serum amyloid A, blood urea nitrogen and packed cell volume at initial presentation were also significantly higher, and those of total protein and albumin were significantly lower in the CDAD group. The development of CDAD was associated with the administration of antimicrobials, surgery and hospitalisation. No significant improvement in mortality was observed for any of the selected treatment in both groups. CONCLUSION: CDAD in…

BACKGROUND: With exotic pet species commonplace in the UK, owners are increasingly seeking veterinary advice regarding the health and welfare of their small mammals and reptiles. This study aimed to assess the confidence of veterinarians in the UK in treating and diagnosing rabbits, guinea pigs, small mammals and reptiles. METHODS: A 41-question survey was promoted via social media, including on interest groups focused specifically at veterinary professionals. A total of 131 practising veterinarians in the UK completed the questionnaire. RESULTS: Frequency of presentation of exotic pets to a practice had a significant effect (P<0.01) on the confidence of veterinarians in treating them. Veterinarians who were presented with exotics more frequently had increased self-reported knowledge of their health and disease and were more confident in treating, diagnosing and anaesthetising them. Knowledge of and confidence in diagnosing and treating exotic pets were significantly less than for dogs and cats (P<0.001).

The evidence suggests that cephapirinimproves subsequent fertility in dairy cows affected by clinical endometritis when compared with no treatment.

BACKGROUND: The vaquita of Mexico is critically endangered, with a population less than 19 individuals in 2018. The population continues to decline and gillnet use continues in vaquita habitat. METHODS: Nine vaquita carcases were examined from 2016 to 2018 to establish cause of death. Concentrations of polychlorinated biphenyls (PCBs), DDTs and polybrominated diphenyl ethers (PBDEs) in blubber (n=3) were determined using gas chromatography/mass spectrometry and faeces tested for domoic acid and saxitoxin. RESULTS: Carcases were in good nutritional status and had lesions and full stomachs consistent with fisheries bycatch. PCB, DDT and PBDE concentrations ranged between 94 and 180 ng/g, 500 and 1200 ng/g and 97 and 210 ng/g lipid weight, respectively, which are low compared with other marine mammals. No saxitoxin or domoic acid was detected. CONCLUSION: These findings support the conclusion that bycatch is the primary source of vaquita population decline and emphasise the need for stronger measures to eliminate gillnets from the Upper Gulf of California, Mexico.

Background In a fattening farm in Southern Germany, skin alterations (urticaria, haemorrhagic diathesis) and high fever were observed in 30% of the pigs 2 weeks after arrival. Feed intake was severely compromised in affected pigs. Methods After detailed clinical observation, blood samples from affected pigs were collected for haematological, PCR and serological investigations. In addition, pathological investigations were performed on one pig. Results and conclusion Analysis of blood parameters revealed a normocytic, normochromic anaemia. A novel porcine haemoplasma species was detected in blood samples of affected pigs and spleen sample of the necropsied pig by PCR. Phylogenetic analyses based on the 16S rDNA showed 99% identity to a novel porcine haemoplasma (‘ Candidatus ( Ca .) M. haemosuis’) species which has recently been described in China. Interestingly, this is the first report of ‘ Ca . M. haemosuis’ in pigs with clinical signs resembling those of Mycoplasma (M) suis and the first description of this novel haemoplasma species outside Asia. On‐farm affected pigs were…

BACKGROUND: While the efficacy of allergen-specific immunotherapy (ASIT) to treat canine atopic dermatitis has been well established, it remains unclear why not all dogs show the same response to treatment. The goal of the study was to determine the relationship between duration of ASIT and two measurements of success: disease severity and concomitant medication sparing effect. METHODS: Data were retrospectively compiled for 145 dogs with atopic dermatitis treated with ASIT. As a measure of treatment compliance, cases were stratified into dogs treated for less than 12 months or for at least 12 months. Treatment efficacy, defined as a reduction in disease severity score (scale 0-10), was compared between both groups, and correlations between treatment success and several related factors were examined. RESULTS: ASIT treatment duration was strongly correlated with treatment efficacy. Animals treated for less than 12 months showed lower efficacy rates (22 per cent) than those treated for at least 12 months (65 per cent). Further, in animals treated for at least 12 months, concomitant…

BACKGROUND: The administration of cytosine arabinoside (CA) by continuous rate infusion (CRI) at the time of diagnosis has been shown to improve the 3-month survival of dogs diagnosed with meningoencephalomyelitis of unknown origin (MUO), compared to subcutaneous administration. The benefit of administering subsequent sequential CA subcutaneous injections is unknown. This study compares the outcomes of a CA CRI protocol with (CRI+subcutaneous group) or without (CRI group) follow-up CA subcutaneous injections; both groups received adjunctive prednisolone. METHODS: Forty-two dogs diagnosed with MUO were recruited (CRI group) and compared with 41 historical control dogs (CRI+subcutaneous group) in a prospective, controlled clinical trial with 36 months of follow-up. RESULTS: Success rates were respectively 64.3 per cent and 65 per cent in the CRI and the CRI+subcutaneous groups at 40 weeks following diagnosis, and 32.5 per cent and 35.9 per cent at 36 months following diagnosis. The median time to relapse was 299 and 285 days for the CRI and the CRI+subcutaneous groups, respectively.…

Background Reproductive efficiency after hydrometra (HD) treatment is usually unsatisfactory. Methods To identify mechanisms involved in low reproductive efficiency of HD‐treated goats, pluriparous dairy goats treated for HD (n=10, HD) or with no reproductive disorders (n=11, control: CONT) were induced to oestrus and superovulated. Goats were mated with fertile bucks and seven days after oestrus, non‐surgical embryo recovery was performed. Embryos were evaluated and gene expression was performed. Results There were no differences (P>0.05) in sexual behaviour parameters, superovulation response, mean number of retrieved structures and viable embryos between groups; although embryo recovery rate was higher (P=0.01) in CONT group. Structures in delayed stage (8–16 cells) were more frequent (P<0.05) in HD (29 vs 1 per cent) goats, as well as the percentage of advanced embryos was greater (P<0.05) for CONT (59.3 vs 33.3 per cent) goats. However, the expression of genes related to apoptosis ( BAX and Bcl‐2 ), trophectoderm differentiation ( CDX2 ) and pluripotency maintenance ( NANOG )…

BACKGROUND: The study aim was to describe conditions seen 'out-of-hours' in equine practice. METHODS: This was a retrospective case series of first opinion 'out-of-hours' cases seen at two equine practices between 2011 and 2013. Data were retrieved on case presentation, diagnostic testing, treatment administered and outcome, and diseases categorised using a systems-based coding system. A hierarchical logistic regression, formulated using a generalised linear model, was used to identify clinical variables associated with a binary outcome of 'critical' cases (required hospitalisation or euthanasia or died). RESULTS: Data from 2602 cases were analysed. The most common reasons for 'out-of-hours' visits were colic (35 per cent, n=923/2620), wounds (20 per cent, n=511/2620) and lameness (11 per cent, n=288/2,620). The majority of cases required a single treatment (58 per cent, n=1475/2550), 26 per cent (n=656/2550) needed multiple treatments and 13 per cent (n=339/2550) were euthanased. Eighteen per cent (n=480/2602) of cases had a critical outcome. Increased heart rate at primary…

BACKGROUND: Due to the technical difficulties with endotracheal intubation of rabbits, a prospective, randomised, controlled study was performed to compare a rabbit-specific supraglottic airway device (SGAD), the v-gel, with endoscopic endotracheal intubation (EEI) in spontaneously breathing rabbits undergoing ovariohysterectomy. METHODS: Fourteen adult female New Zealand white rabbits were randomly allocated to one of two groups based on the method of airway establishment: EEI or v-gel SGAD. Anaesthesia was induced with ketamine and xylazine and maintained using isoflurane in 100 per cent oxygen. Comparisons were made between groups based on placement time of endotracheal tube/SGAD, number of attempts and adjustments, the necessity to increase isoflurane concentrations to maintain a surgical plane of anaesthesia, arterial blood gas values, gross laryngeal evaluation, and laryngotracheal histopathology. RESULTS: in comparison with EEI (P=0.045). Airway trauma was histologically present but clinically negligible in both groups, with no statistically significant differences observed…

BACKGROUND: Veterinary animal welfare advocacy can be undertaken at individual, community, national and international levels. The People's Dispensary for Sick Animals (PDSA), a veterinary charity with 48 Pet Hospitals UK-wide, created a consultative staff network to put an explicit organisational focus on animal welfare-focused veterinary practice. METHODS: PDSA created a national internal committee-a Pet Wellbeing Task Force-composed of veterinary staff representatives. Together with recruited hospital-based Champions who serve as a focus for animal welfare and ethics within their clinical teams, the resulting staff network has described a vision of animal welfare and ethics within companion animal veterinary practice, with accompanying practice-level actions. These actions have formed the basis for national clinical audit, repeated three times since 2013. RESULTS: The audit, alongside targeted interventions, has driven organisational change (eg, new policies), led to measurable improvements in pet wellbeing (eg, improved pain assessment and management) and stimulated collaborative…

BACKGROUND: Cardiac arrhythmias are commonly auscultated during routine physical examinations in horses and determining the underlying electrical abnormality using an ECG is important. The most commonly used device is a three-lead base apex system (Televet), however few practitioners carry this for routine visits. With recognition of the utility of smartphone-based ECGs in humans, dogs and ruminants, the AliveCor single-lead bipolar smartphone-based ECG has gained popularity. The objective of this study was to determine if AliveCor and Televet ECG measurements were comparable in healthy horses using multiple observers. METHODS: ECGs were performed on 15 healthy horses simultaneously using the AliveCor and Televet. RESULTS: There was very good to perfect interdevice and interobserver agreement for heart rate and RR interval measurement, and moderate-to-good interdevice and interobserver agreement for detection of non-pathological arrhythmias. Interdevice agreement for measurement of P-wave and QRS duration, QT, PR and T-peak to T-end interval was poor to fair. Interestingly,…
