Due to this, many institutions have developed their own internal multimodal approach for faculty evaluation and professional advancement review that removes the underlying bias associated with survey results. Ross University School of Veterinary Medicine created a taskforce to evaluate the current teaching assessment practices and provide an alternative method. Based on an extensive literature review, an institutional policy was created using a multimodal approach, combining student evaluations of teaching scores with peer review of teaching, review of teaching materials, mentorship, self-ratings, and self-reflection. The implementation plan for this policy is described to allow for a teaching evaluation process built on a philosophy of mentorship, guidance, and self-reflection; as well as the use of external professional exam metrics to review the institutional academic quality at large.}, journal={Journal of veterinary medical education}, author={Rolph, Kerry and King, Ailbhe and Lardé, Hélène and Kim, ST and Ragland, Natalie and Hervé, Claude LP and French, Hilari and Gilbert, Robert}, year={2023}, month={Jan} }

ANIMALS 201 Jersey cows. METHODS Colostrum was collected from 28 pools and heat treated before being fed to calves or stored. Parity, total number of cows contributing to the pool, individual cow colostral volume contributions, and total volume of each colostrum pool were recorded. Colostrum IgG concentrations in individual and pooled (pre- and post-heat treatment) samples were analyzed by radial immunodiffusion and Brix refractometry. Colostral IgG concentration of ≥ 50g/L was considered the current recommended dairy industry standard for acceptable colostrum quality. Multivariable models were performed to determine factors affecting pooled colostral IgG concentrations. The minimum colostral IgG concentration required for pooling to achieve the recommended total mass of at least 200g IgG to be fed to a calf was calculated. RESULTS Total pool volume and the number of cows contributing to the pool were significant factors affecting IgG concentration. Colostrum pools from ≤ 7 cows, with a minimum pool IgG concentration of 70.4 g/L (22.9% Brix) or colostrum pool volume ≤ 40 L, with a minimum pool IgG concentration of 66.2 g/L (21.8% Brix) achieved the recommended total mass of at least 200g IgG in 4L of colostrum. CLINICAL RELEVANCE When feeding pooled colostrum, IgG concentrations higher than the industry standard of 50 g/L is recommended to reduce the risk of failure of transfer of passive immunity in calves.}, number={3}, journal={Journal of the American Veterinary Medical Association}, publisher={American Veterinary Medical Association (AVMA)}, author={King, Ailbhe and French, Hilari and Toka, Felix N. and Bandlow, Katherine S. and Chigerwe, Munashe}, year={2023}, month={Dec}, pages={1–7} }

Several studies report conflicting evidence regarding the ability of feeding pooled colostrum to achieve ATPI. Pooling colostrum is practical and efficient for some dairies, and recommendations are required to prevent failure of transfer of passive immunity (FTPI) in calves following pooling. This study aimed to determine the effect of pooling colostrum on serum IgG concentrations, FTPI, and preweaning mortality in calves. A prospective study was performed on two conventional Jersey dairy farms where heat treatment of colostrum occurred in the same colostrum processing kitchen. Four to 10 cows contributed to colostrum pools. A sample of the colostrum pool fed to the calves and serum from calves at 24–72 h was collected for IgG concentration determination by single radial immunodiffusion assay. Multivariable and logistic regression analyses were performed to evaluate factors that predicated serum IgG concentrations and the probability of FTPI, respectively. A Cox proportional hazard model analysis was performed to determine risk factors for mortality over the preweaning period. A total of 164 calves fed 28 colostrum pools were enrolled. Birth weight, number of colostrum feedings and pool IgG concentrations were significant predictors of calf serum IgG concentrations at 24–72 h, whereas the number of colostrum feedings and age at bleeding to determine passive transfer status were not significant predictors of calf serum IgG concentrations at 24–72 h. The prevalence of FTPI was 4.9%. Birth weight, pool IgG concentrations, number of colostrum feedings, and age at bleeding to check for passive transfer status were not significant predictors of the probability of FTPI at 24–72 h. The incidence of mortality was 4.3%. Passive transfer status was not a predictor of mortality. Our study demonstrates the effect of pooling colostrum on serum IgG concentrations even in herds where colostrum with higher median colostrum IgG concentrations is fed to calves. The results emphasize the recommendations to assess pooled colostrum IgG concentrations before feeding calves.}, journal={FRONTIERS IN VETERINARY SCIENCE}, publisher={Frontiers Media SA}, author={Bandlow, Katherine S. and King, Ailbhe and Kennicutt, Kelsie C. and Brody, Shoshana and Chigerwe, Munashe}, year={2023}, month={Feb} }

The first four weeks of age are critical for reducing calf morbidity and mortality. It is well documented that colostrum is paramount to neonatal nutrition and passive immunity, however, adaptation to extra-uterine life starts early during embryonic development. Therefore, successful calf rearing strategies are underpinned by adequate maternal nutrition during gestation, and good colostrum management. A deeper understanding of these interactions paves the way for developing strategies to improve immune responses to environmental pathogens, optimal growth and timely attainment of puberty in calves. The literature reviewed here shows that there are opportunities to enhance the future performance of cattle paying attention to the interaction of nutrition and immunity at each developmental stage. Therefore, the objective of this review is to give the reader an overview of interactions between immunity, growth and puberty in dairy calves and highlight how these influence future performances.}, number={5}, journal={Animals}, publisher={MDPI AG}, author={Cardoso, Claudia L. and King, Ailbhe and Chapwanya, Aspinas and Esposito, Giulia}, year={2021}, month={Apr}, pages={1212} }

ANIMALS Goats (n = 9), sheep (12), and pigs (7) that sustained burn injuries from wildfires. PROCEDURES Medical records were searched to identify goats, sheep, and pigs that had burn injuries associated with California wildfires in 2006, 2015, and 2018. Data regarding signalment, physical examination findings, treatments, clinical outcomes, time to discharge from the hospital, and reasons for death or euthanasia were recorded. RESULTS The eyes, ears, nose, mouth, hooves, perineum, and ventral aspect of the abdomen were most commonly affected in both goats and sheep. In pigs, the ventral aspect of the abdomen, distal limb extremities, ears, and tail were most commonly affected. The median (range) time to discharge from the hospital for goats and pigs was 11 (3 to 90) and 85.5 (54 to 117) days, respectively. One of 9 goats, 12 of 12 sheep, and 5 of 7 pigs died or were euthanized. Laminitis and devitalization of distal limb extremities were common complications (13/28 animals) and a common reason for considering euthanasia in sheep and pigs.

Pooling can result in dilution when colostrums with high and low IgG concentrations are mixed, thereby predisposing calves to failure of passive immunity. The objectives of this study were to compare IgG concentrations in colostrum from individual cows with colostrum pooled from several cows, and assess serum IgG concentrations, morbidity, and mortality among calves fed colostrum from their own dam, from a different cow, or pooled from several cows. We hypothesized that pooling colostrum reduces IgG concentration due to dilution compared with colostrum from individual cows, and that calves fed pooled colostrum achieve lower serum IgG concentrations than calves fed colostrum from individual cows. Calves were randomly assigned to 1 of 3 groups: (1) fed colostrum from their own dam (n = 20); (2) fed colostrum from a different dam (n = 20); or (3) fed pooled colostrum (n = 18). A sample of colostrum fed to each calf was collected. Serum samples were collected from calves at birth (0 h) and at 24 h after colostrum feeding. Colostrum and serum IgG concentrations were measured by radial immunodiffusion. Calves were weighed at birth and at weaning, and the health status of each calf was assessed twice daily. Health assessment was based on general demeanor, rectal temperature, fecal consistency, respiratory rate, and the presence of cough, nasal, or ocular discharge. Colostrum and serum IgG concentrations, and weaning weights were compared using ANOVA. Associations between group and morbidity or mortality rates were compared using χ<sup>2</sup> or Fisher's exact tests. Median and 95% confidence intervals (95% CI) of IgG concentrations of colostrum were 99.4 (81.8–111.5), 95.2 (84.1–107.2), and 100.7 (90.5–104.4) g/L for own dam, different dam, and pooled groups, respectively. We did not find any differences in colostrum IgG concentrations among the colostrum sources. Median (95% CI) serum IgG concentrations at 24 h were 52.0 (45.6–65.9), 55.7 (51.2–65.9), and 53.1 (46.2–63.7) g/L for calves that received colostrum from own dam, different dam, and pooled, respectively. All calves achieved adequate passive immunity. Serum IgG concentrations at 24 h, weaning weights, and proportions of morbidity and mortality were not different among the 3 groups. Our results suggest that on dairy farms where median colostrum IgG concentrations are high and colostrum management is optimal, pooling has a minimal effect on passive immunity and subsequent calf health.}, number={2}, journal={Journal of Dairy Science}, publisher={American Dairy Science Association}, author={King, Ailbhe and Chigerwe, Munashe and Barry, John and Murphy, John P. and Rayburn, Maire C. and Kennedy, Emer}, year={2020}, month={Feb}, pages={1894–1899} }

Limited information is available describing complications associated with IVCs. Hypotheses Prevalence of IVC infections in hospitalized ruminants is >50%. Intravenous catheters maintained for >5 days are more likely to be infected than those maintained for <5 days. Intravenous catheters placed non‐aseptically have a higher risk for infection than those placed aseptically. Animals Thirty‐four cattle, 39 goats, and 33 sheep were hospitalized in a university teaching hospital. Methods Prospective observational study. The IVCs from cattle, goats, and sheep admitted for medical and surgical procedures were randomly selected and submitted for bacteriological culture and susceptibility testing. Results Prevalence values (95% confidence interval) of infected catheters were 61.8 (45.5, 78.1), 51.3 (35.3, 66.7), and 42.4% (25.2, 58.8) in cattle, goats, and sheep, respectively. Coagulase‐negative Staphylococcus spp was the most frequently isolated bacterium. Catheter type/placement technique was a significant ( P = .03) predictor of IVC infection in goats but not in cattle ( P = .65) and sheep ( P = .47). Antibiotic use and reason for catheter placement were not significant predictors of IVC infection in all species. Catheters maintained for >4 days had a higher likelihood of being infected than those maintained for <4 days in all species. Conclusions and Clinical importance Clinicians should consider replacing catheters maintained for >4 days to reduce IVC infection.}, number={1}, journal={Journal of Veterinary Internal Medicine}, publisher={Wiley}, author={King, Ailbhe and Byrne, Barbara A. and Chigerwe, Munashe}, year={2019}, month={Dec}, pages={330–338} }
