Background: Pediculosis in cattle causes significant itching, irritation and stress to the animal, often resulting in skin damage and poor coat condition. The control of bovine pediculosis in Ireland is based predominantly on commercial insecticides belonging to one of two chemical classes, the synthetic pyrethroids and the macrocyclic lactones. In recent years, pyrethroid tolerance has been reported in a number of species of livestock lice in the United Kingdom and Australia.
Results: In this pilot survey, lice were detected in 16 (94%) out of 17 herds visited. Two species of lice, Bovicola bovis and Linognathus vituli were identified. In vitro contact bioassays showed evidence of deltamethrin tolerance in Bovicola bovis collected from 4 farms. This was confirmed by repeatedly assessing louse infestations on treated animals on one farm.
Conclusions: To our knowledge this is the first record of insecticide tolerant populations of lice in Irish cattle. The results also provide new data on the species of lice infesting beef cattle in Ireland and the prevalence and control of louse infestations in Irish beef cattle herds.

Chlamydia spp. are prevalent zoonotic pathogens that infect a wide variety of host species. Chlamydia abortus (C. abortus) infection in yaks has been reported in Gansu and Qinghai province, China. However, no data about C. abortus infection are available in yaks in Tibet, China. A total of 938 serum samples was collected from yaks in Tibet, China and specific antibodies against C. abortus were detected by the enzyme-linked immunosorbent assay (ELISA). The results showed that the overall seroprevalence of C. abortus in yaks was 104/938 (11.1 %, 95 % confidence interval [CI] 9.1-13.1). The prevalence in female and male yaks was 59/556 (10.6 %, 95 % CI 8.0-13.2) and 45/382 (11.8 %, 95 % CI 8.5-15.0), respectively with no significant difference (p > 0.05). The seroprevalence of antibodies to C. abortus in yaks ranged from 8.0 to 18.2 % among the six different areas, and the difference was also without statistical significance (p > 0.05). The prevalence among different age groups ranged from 7.0 to 15.9 %, with a higher prevalence among 1 to 2 years age category. The results demonstrate the presence of C. abortus infection in yaks in Tibet and may pose a risk for the general yak populations in addition to its potential impact on public health and the local Tibetan economy. To our knowledge, this is the first seroprevalence survey of C. abortus in yaks in Tibet, China.

Background: The Biological Isolation and Containment Unit (BICU) is a subunit of the Teaching Hospital of the Faculty of Veterinary Medicine of the University of Lisbon, Portugal, for the admission of animals with confirmed infectious diseases or under clinical suspicion and waiting for a diagnosis. As a high-risk environment for the transmission of infectious agents, it is extremely important to implement programs for the surveillance of nosocomial microorganisms in these facilities. The purpose of this study was to evaluate the level of bacterial contamination of the BICU environmental surfaces and to implement corrective actions on disinfection protocols. Swab samples were collected from selected environmental surfaces in 3 different areas of the BICU (isolation, work, and preparatory rooms) to evaluate the total aerobic bacterial load and investigate the presence of 4 nosocomial microorganisms: vancomycin-resistant Enterococcus spp., methicillin-resistant Staphylococcus aureus, 3rd-generation cephalosporin-resistant Escherichia coli, and carbapenem-resistant Pseudomonas aeruginosa. Bacterial quantification was performed by using non-selective media, while specific selective media were used for the isolation of the target microorganisms. Isolates were identified based on their macro and microscopic characteristics and their biochemical profile. Subsequently, new disinfection protocols were implemented, and their effectiveness evaluated.
Results: The surfaces with the highest bacterial load in the isolation, preparatory, and worker's rooms were the cages, hand-held sponge, and telephone, respectively. Regarding the 4 pathogens investigated, Enterococcus spp. were the most frequently isolated (11.3%), followed by E. coli (1.5%) and P. aeruginosa (1.5%). One of the P. aeruginosa isolates obtained was resistant to imipenem. In the end, new disinfection protocols were implemented, which proved to be effective in reducing bacterial counts by 99.99% in cages and the sponge, and by 90 to 99% on the telephone.
Conclusions: This study allows to conclude that the cages and the human contact surfaces were the most contaminated in the isolation rooms. Nevertheless, the new disinfection strategies seemed to be effective in reducing environmental contamination, including by some potentially nosocomial agents, although more samples must be analyzed for definitive conclusions. These results may contribute to highlight the importance of infection prevention and control measures, as fundamental tools to reduce the spread of infectious agents in the hospital environment.

Background: As part of clinical wound assessment in bovine surgery, discrepancies in skin temperature are evaluated by placing the back of the hand on the area to be examined. Generally, an increased skin temperature at the wound site for a prolonged period is considered as an indicator of impaired wound healing. The aim of this study was to verify the reliability of palpation under bovine practice conditions using laparotomy as an example. Fourteen cows (German Holstein) with a left displacement of the abomasum (LDA) without other severe concurrent diseases were examined preoperatively and once daily for ten days after surgery. The skin temperature of the wound site in the right flank was assessed by palpation, followed by thermographic evaluation using an infrared camera after a 45-min acclimatisation period, under standardised conditions in a closed examination room daily for 10 days.
Results: All the incisions healed without clinical detectable perturbances. The ambient temperature range during the study period was 7.8 - 24.1 °C. Two groups were retrospectively defined according to the ambient temperature: high ambient temperature (HT group; median: 20.2 °C 25/75 quartile: 18.5 °C / 21.7 °C; n = 6) and low ambient temperature (LT group; 10.8 °C; 9.4 °C / 12.8 °C; n = 8). The temperature differences (Δϑ) between the mean skin temperature of the wound site and a defined reference area cranial to the wound were assessed. A significant negative correlation was found between the ambient temperature (ϑAmb) and Δϑ (r=-0.51; P < 0.001). The Δϑ was postoperatively higher in the cows in the LT group (median of the individual animals 0.8-2.5 °C) than in the HT group (0.1-0.5 °C; P < 0.05). In contrast to the thermographic findings, manual palpation rarely detected local hyperthermia (> 1 °C) at the wound site (sensitivity 0.20; specificity 0.96).
Conclusions: The infrared thermography provides a more reliable assessment of temperature changes at the wound site in comparison to manual palpation. The ambient temperature markedly affects the extent of local hyperthermia at the wound site.

Background: Hot-iron disbudding is a common management procedure to prevent horn growth in calves. The study objective was to examine effect of age, breed and sex on horn bud size of dairy-bred and suckler-bred calves at time of disbudding.
Results: The left and right horn bud size (diameter and height in mm) of 279 calves, including dairy-bred Holstein-Friesian (Male (M) = 88) and 191 suckler-bred (86 Charolais, CH; (M = 39, Female (F) = 47), 67 Limousin, LM; (M = 32, F = 35) and 38 Simmental, SI; (M = 22, F = 16) sired)) was measured using a digital calliper at time of disbudding. Calves were retrospectively assigned to two age categories at time of disbudding: 1), 14 to 28 days (d) old and 2), 29 to 60 d old. Holstein-Friesian M calves had a greater horn bud diameter (16.97 v.14.45 mm) and height (7.79 v. 5.00 mm) compared to suckler-bred M calves (P < 0.01), with no difference (P > 0.05) among the suckler-bred calves. Suckler-bred M calves had a greater horn bud diameter (14.46 vs 13.29 mm) and height (5.01 vs 3.88 mm) compared to suckler-bred F calves (P < 0.05). The slopes of the lines of best fit show that horn bud diameter and height increased with age (P < 0.05) for HF, SI male and CH female calves while there was no relationship with age (P > 0.05) for CH and LM male calves, or for SI and LM female calves. Linear regression of age with diameter and with height for each breed and sex showed high variability in the data as indicated by R-squared values ranging from 0.003-0.41 indicating that in the case of the diameter and the height, the weight of the fitting effect was poor.
Conclusions: Calf age is not a good predictor of horn bud size and recommendations for the disbudding of calves should be based on horn bud size and not on age. The implications of these findings are that calves should be disbudded while horn development is still at the bud stage and when the bud is large enough to be easily palpable/visible, but not so large that disbudding could lead to severe tissue trauma.
背景:热铁脱芽是一种常见的管理程序,以防止小牛角生长。研究目的是考察年龄、品种和性别对乳种和乳种犊牛脱芽时角芽大小的影响。结果279头犊牛的左右角芽大小(直径和高度,单位为mm),其中乳种荷尔斯泰因-弗里马(公(M) 88头)和乳种191头(夏洛莱86头,CH;(M = 39,女(F) = 47), 67利穆赞,LM;(M = 32, F = 35)和38 Simmental, SI;(M = 22, F = 16))在脱芽时使用数字卡尺测量。小牛在脱芽时被回顾性地分为两个年龄类别:1),14至28日龄(d)和2),29至60日龄。在哺乳犊牛中,荷斯泰因-弗里马M犊牛的角芽直径(16.97 vs .14.45 mm)和高度(7.79 vs . 5.00 mm)均大于哺乳犊牛(P < 0.05)。哺乳M犊牛的角芽直径(14.46 mm比13.29 mm)和角高(5.01 mm比3.88 mm)均大于哺乳F犊牛(P < 0.05)。各品种和性别的年龄随直径和身高的线性回归表明,数据具有很大的变异性,r平方值在0.003-0.41之间,表明在直径和身高的情况下,权重拟合效果较差。结论:犊牛年龄不能很好地预测牛角芽的大小,建议犊牛的脱芽应基于牛角芽的大小,而不是年龄。这些发现的含义是,小牛应该在角发育仍处于萌芽阶段时脱芽,并且当芽足够大以容易触摸/可见时,但不要太大,以免脱芽可能导致严重的组织损伤。

Background: Peripheral parenteral nutrition (PPN) is increasingly considered as an alternative to central parenteral nutrition (CPN) given the higher cost and more frequent clinical complications associated with the latter. However, the assessment of potential risks and benefits of PPN in critically ill pediatric canine patients has not been extensively performed. In this study, we aimed to explore the effect of short-term, hypocaloric PPN on weight loss, length of hospital stay, the incidence of complications, adverse effects, and mortality in critically ill pediatric canine patients.
Results: Between August 2015 and August 2018, a total of 59 critically ill pediatric canine patients aged from 1 to 6 months admitted at the Veterinary Sciences Research Institute of the Autonomous University of Baja California were included in this non-randomized clinical trial. Canine pediatric patients were initially allocated to 3 groups: 11 in group 1 receiving parenteral nutrition (PN) supplementation equivalent to 40% of the resting energy requirement (RER), 12 in group 2 receiving supplementation of 50% of the RER, and 36 in group 3 receiving no PN supplementation. After establishing that there was no significant difference between 40 and 50% of PN supplementation, these groups were not separated for downstream analysis. Similar lengths of hospital stays were noted among study subjects who received PN supplementation and those who did not (4.3 ± 1.5 vs. 5.0 ± 1.5, days, p = 0.097). No metabolic-, sepsis- or phlebitis-related complications were observed in any animal in the PPN supplemented group. Higher mortality (19.4% vs. 0%, p = 0.036), and a greater percentage of weight loss (9.24% vs. 0%, p < 0.001) were observed in patients who received no supplementation.
Conclusion: Even though short-term, hypocaloric PPN did not reduce the length of hospital stay, it was associated with lower mortality and resulted in mitigation of weight loss. In contrast to previous studies evaluating central and peripheral parenteral nutrition protocols, we observed a lower frequency of metabolic, septic, and phlebitis complications using a 40-50% parenteral nutrition treatment.

背景:外周肠外营养(PPN)越来越被认为是中心肠外营养(CPN)的替代方案,因为后者成本更高,临床并发症更频繁。然而,对PPN在重症儿科犬患者中的潜在风险和益处的评估尚未广泛进行。在本研究中,我们旨在探讨短期低热量PPN对重症儿科犬患者体重减轻、住院时间、并发症发生率、不良反应和死亡率的影响。结果:2015年8月至2018年8月,在下加利福尼亚自治大学兽医科学研究所共收治了59例1至6个月的重症儿科犬患者,纳入了这项非随机临床试验。犬儿患者最初被分为3组:1组11例接受相当于静息能量需取量40%的肠外营养(PN)补充,2组12例接受相当于静息能量需取量50%的肠外营养补充,3组36例不接受肠外营养补充。在确定PN添加量为40%和50%之间没有显著差异后,这些组没有被分开进行下游分析。在接受PN补充和未接受PN补充的研究对象中,住院时间相似(4.3±1.5 vs 5.0±1.5,天,p = 0.097)。在PPN补充组中,没有观察到任何动物的代谢、败血症或静脉炎相关并发症。更高的死亡率(19.4% vs. 0%, p = 0.036)和更高的体重减轻百分比(9.24% vs. 0%, p)结论:即使短期低热量PPN并没有缩短住院时间,但它与较低的死亡率相关,并导致体重减轻。与先前评估中央和外周肠外营养方案的研究相比,我们观察到使用40-50%的肠外营养治疗可降低代谢、脓毒症和静脉炎并发症的发生率。在我们的研究中使用的肠外营养治疗干预可以减少pn相关的不良反应,促进危重犬患者的良好预后。需要更大规模的研究来证实这些观察结果。

Background: There has been increasing concern expressed about the welfare of exotic pets worldwide. For the purposes of this article, an exotic pet is considered to be a non-domesticated species, where there are knowledge gaps on good practice (minimum standards of care), veterinary diagnostics and treatments. The categories of exotic pets included in this study were: small mammals (< 20 kg), large mammals (> 20 kg), birds, reptiles, amphibians, fish and invertebrates. Dogs, cats, rabbits, hamsters, gerbils, guinea pigs, mice, rats, and ferrets were excluded from the study. An online survey of pet owning staff at University College Dublin was conducted between July and August 2020 to provide the first empirical data for Ireland. In this pilot study (the first in this thematic series) we aim to characterise exotic pet ownership, the challenges and benefits of keeping exotic pets, and access to veterinary services from the pet owner's perspective.
Results: Using an online survey this pilot study gathered evidence from 83 domestic and 32 exotic pet owners within the staff (n = ~ 3600 FTE) at University College Dublin, the largest third level institution in Ireland. The prevalence of exotic pet ownership was determined to be 34.4 % of households with more than 10 % of pet owning households owning only exotic pets. Fish (n = 15), reptiles (n = 13) and birds (n = 8) were the most common types of exotic pets. Thirty-four per cent of exotic pet owners never sought veterinary services, the most common reasons were due to lack of local veterinary specialists (n = 10) and good owner knowledge (n = 8). However identifying appropriate guidance on the animals' needs was a common challenge for exotic pet owners (n = 13). A reasonable monthly cost of caring for an exotic ranged from €20-180, depending on the species.
Conclusions: This pilot study contains important implications for veterinary education to support the veterinary community with providing services to the exotic pet owning community. Policy issues with exotic pet ownership also need to be considered and further research into the proposed strategies to support the health and welfare of exotic pets should be carried out such as the introduction of white lists and guidelines on responsible pet ownership.

Results: Using an online survey this pilot study gathered evidence from 63 veterinary professionals currently working in private practice in Ireland. The prevalence of veterinary services for exotic pets in Ireland was determined to be 82% of small and mixed animal clinics of respondents' practices ranging from 9.1 to 100% for different categories of exotic pets. The most common issues encountered in practice with exotic pets were related to nutrition, environment, and behaviour followed by clinical diseases such as respiratory, infectious, and gastrointestinal issues. The most common concerns veterinary professionals had with exotic pet ownership related to the lack of owner knowledge as well as the lack of veterinary knowledge and accessible resources. The most common strategic initiatives indicated by veterinary professionals included black or white lists (to prohibit and permit the keeping of exotic pet species respectively), licensing for owners and increased availability of CPD for veterinary professionals.
Conclusions: More than four in every five veterinary professionals in small or mixed animal practices surveyed were willing to treat exotic pets and in many cases they already were. A scaffold for best practice is required to support the health and welfare of exotic pets and responsible ownership. Keystones include veterinary education to support veterinary professionals with daily practice, establishing a white list of exotic species that are suitable as pets, registration at the point of purchase to enable traceability for biosecurity purposes and research to identify care standards to support the health and welfare of exotic pets.

Background: In addressing the threat of antimicrobial resistance, it is critical to understand the barriers to the uptake of strategies for the reduction of antimicrobial use (AMU) in the pig industry. In several EU countries, factors such as education level, habits and social pressures are recognised as affecting farmers' decision-making process in relation to AMU. However, there is a lack of information on the Irish scenario. The aim of this study was to investigate pig farmers' perspectives and their behaviour towards AMU to identify potential barriers to effectively reduce AMU in Irish pig production. We conducted face-to-face semi-structured interviews with 30 pig farmers, 5 pig veterinarians and 4 focus groups of pig farm personnel. We employed qualitative analyses to explore the objective of the study.
Results: Qualitative analysis revealed six convergent themes as potential barriers: perceptions about the need for AMU on farm, concept of animal welfare and associated management practices, legislation, culture, economics and standards of communication/type of advice-network. Overall, pig farmers believed that there is poor communication between stakeholders (i.e. farmers, vets and advisors) and a lack of reliable people to approach for advice. They considered themselves as operating responsibly in terms of AMU compared to their national and international colleagues and expressed the importance of a so-called 'Irish solution' to the problem of AMU because it was associated with what 'has always been done' and was therefore considered reliable and safe.
Conclusions: Barriers and challenges were in line with those identified in other EU countries highlighting similarities in behavioural and attitudinal patterns among pig farmers. Overall, farmers appeared to be more likely to rely on previous experiences or to wait for an imposed change (e.g. legislation) instead of taking personal action. Thus, considerable behavioural and attitudinal changes are needed to adopt a more responsible AMU in Irish pig production and to develop effective intervention strategies.

Background: Selenitetriglycerides are biologically active, organic forms of selenium formed as a result of the modification of selenic acid and sunflower oil. Studies in rats have shown that they are well absorbed and of low toxicity. There are no published studies on selenitetriglycerides supplementation in calves.
Results: In this study, selenitetriglycerides were administered once orally on the 2nd day of life at a dose of 0.5 or 1 mg Se/kg body weight to each of six Holstein-Friesian calves while six control calves were not supplemented. Blood for determination of selenium concentration, glutathione peroxidase activity, haematological parameters, aspartate aminotransferase, creatine kinase, and lactate dehydrogenase activities and glucose, total protein, albumin, triglycerides, cholesterol, urea, and creatinine concentration was collected before supplementation (day 0) and 1, 2, 5, 10 and 14 days after supplementation. Selenitetriglycerides administration increased (P < 0.01) serum selenium concentration in supplemented calves as early as day1, from a mean of 63.4 to 184.22 µg/l in calves receiving selenium at a dose of 0.5 mg/kg BW, and from 63.17 to 200.33 µg/l in calves receiving 1 mg/kg. Serum selenium concentrations remained significantly higher compared to the control group throughout the experiment. Glutathione peroxidase activity was higher in supplemented than control calves, significantly so in animals receiving the 1 mg/kg dose of Se on the 10th and 14th days (P < 0.05). There were no significant differences in the haematological and biochemical parameters between the groups.
Conclusions: This experiment showed that supplementation with selenitetriglycerides could significantly improve blood selenium status in calves without adverse effects on haematological or biochemical parameters. These findings are essential prerequisites for future studies on selenitetriglycerides supplementation to manage clinical selenium deficiency in calves.
