Circadian rhythms are a process of the sleep–wake cycle that regulates the physical, mental and behavioural changes in all living beings with a period of roughly 24 h. Wearable accelerometers are typically used in livestock applications to record animal movement from which we can estimate the activity type. Here, we use the overall movement recorded by accelerometers worn on the necks of newborn calves for a period of 8 weeks. From the movement data, we calculate 24 h periodicity intensities corresponding to circadian rhythms, from a 7-day window that slides through up to 8-weeks of data logging. The strength or intensity of the 24 h periodicity is computed at intervals as the calves become older, which is an indicator of individual calf welfare. We observe that the intensities of these 24 h periodicities for individual calves, derived from movement data, increase and decrease synchronously in a herd of 19 calves. Our results show that external factors affecting the welfare of the herd can be observed by processing and visualising movement data in this way and our method reveals insights that are not observable from movement data alone.

This case report describes the investigation of the first outbreak of bovine besnoitiosis in a beef/suckler herd in Ireland. Infection with Besnoitia besnoiti was suspected by the attending veterinarian following clinical examination of a chronically affected cow with areas of alopecia and marked skin thickening. Diagnosis of besnoitiosis was confirmed by Cork Regional Veterinary Laboratory based on histopathology of skin biopsies. Subsequent serological investigation using enzyme-linked immunosorbent assay testing revealed a 17.8% seroprevalence within the herd, with 33% of adult cows seropositive. A clinical whole-herd investigation found an overall clinical prevalence of besnoitiosis of 38.8%, based on the presence of sclerocysts and/or vulval cysts. There was poor agreement between serological and clinical findings. In contrast to serological findings, 83.8% of 18-month-old heifers and bulls had sclerocysts. Due to the high prevalence of besnoitiosis and the challenges of controlling spread, this pedigree herd was discontinued by the farmer.

Background Retention of veterinary practitioners has arisen as a significant problem in recent years in Ireland. No prior Irish peer-reviewed publications have addressed this problem. An online questionnaire was available through social media and via email to Irish vets from January to November 2019. The aim of this survey was to ascertain the factors contributing to the problem of vet retention in Ireland. Results A total of 370 eligible responses were received. The median age of respondents was 31 and the gender balance was 250 females (68%) to 118 males (32%). The majority of respondents worked in clinical practice 322 (89%), with 138 (42.8%) in mixed practice, 115 (35.7%) in small animal practice, 49 (15.2%) solely with farm animals and 20 (6.2%) in equine practice. Fifty-four percent of respondents described themselves as likely to be leaving their current job within two years and 32.8% as being likely to leave the profession. In total, 44 variables were assessed by univariate analysis and 27 variables were significantly (P < 0.05) associated with the likelihood of a respondent leaving their current job within 2 years (LCJ2), as a proxy measure of the problem of retention. All variables significant on univariate analysis at P < 0.2 were included in a multivariable logistic regression model. Factors associated with LCJ2 included satisfaction with work-life balance (Odds Ratio (OR) 0.33); satisfaction with working hours (OR 0.2); number of years qualified (OR 0.91); position as a practice owner/partner/director (OR 0.15); and log10salary (OR 0.03). Four variables were retained in a separate multivariable linear regression model as significant (P < 0.05) predictors of log10salary. Log10salary increased with years qualified. Males had an increased salary compared to females irrespective of years qualified. Part-time employees, vets on maternity leave or postgraduate vets had a lower log10salary. Compared to veterinary employees, self-employed or locum vets had a higher log10salary. Conclusions Veterinary employers should consider salary, working hours and the facilitation of a good work-life balance in order to successfully retain veterinary employees. The significant difference in salaries currently offered to male and female vets, and the high percentage of respondents considering leaving the profession, are important findings and warrant further investigation.
