Modeling the effects of steroid implant use on the environmental and economic sustainability of Brazilian beef production.

Brazilian beef systems contribute 14.9% of global beef production, therefore given climate change concerns, there is a clear need to reduce environmental impacts while maintaining economic viability. This study evaluated the hypothesis that steroid implant use in Brazilian beef cattle would reduce resource use, greenhouse gas (GHG) emissions and economic costs of production, thereby improving environmental and economic sustainability.

A multi-country study to assess the effect of a treatment with moxidectin pour-on during the dry period on milk production in dairy cows.

A randomized clinical study was conducted in a total of 45 commercial dairy farms in France (14 farms), Germany (28 farms) and the UK (3 farms) to evaluate the effect of an anthelmintic treatment on milk yield in the subsequent lactation. A total of 1287 animals with suspected exposure to Ostertagia ostertagi were included in the study. Animals were treated during the dry period (7-77days before parturition) with moxidectin pour-on (Cydectin 0.

Veterinary Students' Perspectives on Resilience and Resilience-Building Strategies.

In recent years, resilience has been lauded as a valuable, even necessary, facet of an effective veterinary practitioner. This study describes a mixed-methods research exploration of the impact of a self-care and mental well-being teaching intervention on the self-reported resilience of 105 first-year veterinary students enrolled at the School of Veterinary Medicine, University of Surrey, UK. Quantitative data were obtained through a questionnaire, the 10-item Connor-Davidson Resilience Scale (CD-RISC 10), which students completed before and after the teaching intervention.

Comparative efficacy of tulathromycin and tildipirosin for the treatment of experimental infection in calves.

The objective of this negative controlled, blinded, randomised, parallel group study was to compare the efficacy of two injectable macrolide antimicrobials, tulathromycin and tildipirosin, administered by single subcutaneous injection at dose rates of 2.5 and 4.0 mg kg bodyweight, respectively, in the treatment of an experimentally induced infection in calves.

Anthelmintic resistance to ivermectin and moxidectin in gastrointestinal nematodes of cattle in Europe.

Anthelmintic resistance has been increasingly reported in cattle worldwide over the last decade, although reports from Europe are more limited. The objective of the present study was to evaluate the efficacy of injectable formulations of ivermectin and moxidectin at 0.2 mg per kg bodyweight against naturally acquired gastro-intestinal nematodes in cattle.

The Life of Meaning: A Model of the Positive Contributions to Well-Being from Veterinary Work.

We present a veterinary model of work-derived well-being, and argue that educators should not only present a (potentially self-fulfilling) stress management model of future wellness, but also balance this with a positive psychology-based approach depicting a veterinary career as a richly generative source of satisfaction and fulfillment. A review of known sources of satisfaction for veterinarians finds them to be based mostly in meaningful purpose, relationships, and personal growth. This positions veterinary well-being within the tradition of eudaimonia, an ancient concept of achieving one's best possible self, and a term increasingly employed to describe well-being derived from living a life that is engaging, meaningful, and deeply fulfilling.

Further validation of the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) in the UK veterinary profession: Rasch analysis.

Purpose: To examine the psychometric properties of the 14-item Warwick-Edinburgh Mental Well-being Scale (WEMWBS) in the UK veterinary profession by the application of Rasch analysis, and to assess the external construct validity of the derived interval scale measurements.

Methods: Data sets were derived from two independent cross-sectional surveys of the veterinary profession (n = 8,829 and n = 1,796). Rasch analysis (n = 500) included response option thresholds ordering, tests of fit, differential item functioning, targeting, response dependency, and person separation index (PSI).

The role of combination anthelmintic formulations in the sustainable control of sheep nematodes.

Combinations of anthelmintics with a similar spectrum of activity and different mechanisms of action and resistance are widely available in several regions of the world for the control of sheep nematodes. There are two main justifications for the use of such combinations: (1) to enable the effective control of nematodes in the presence of single or multiple drug resistance, and (2) to slow the development of resistance to the component anthelmintic classes. Computer model simulations of sheep nematode populations indicate that the ability of combinations to slow the development of resistance is maximised if certain prerequisite criteria are met, the most important of which appear to concern the opportunity for survival of susceptible nematodes in refugia and the pre-existing levels of resistance to each of the anthelmintics in the combination.

Neutralising antibody responses in cattle and sheep following booster vaccination with two commercial inactivated bluetongue virus serotype 8 vaccines.

Cattle and sheep that had received a primary course of vaccination with an inactivated bluetongue virus serotype 8 (BTV-8) vaccine were booster vaccinated 6 or 12 months later with the homologous vaccine or an alternative inactivated BTV-8 vaccine and neutralising antibody responses were determined. Antibody titres to the alternative vaccine were significantly higher than to the homologous vaccine (P=0.013) in cattle.

Validation of the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) as an overall indicator of population mental health and well-being in the UK veterinary profession.

The Warwick-Edinburgh Mental Well-being Scale (WEMWBS) was evaluated as an indicator of mental health and well-being within the veterinary profession in a cross-sectional study among a representative sample of 3200 veterinary surgeons practising in the UK. The WEMWBS mean score for the sample was 48.85 (95% confidence interval 48.

Psychosocial working conditions and work-related stressors among UK veterinary surgeons.

Background: Anecdotally, veterinary surgeons report high levels of work-related stress.

Aims: To investigate psychosocial working conditions, self-reported causes of work-related stress and satisfaction among a representative sample of vets practising in the UK.

Methods: A cross-sectional study using a questionnaire mailed to a stratified random sample of 3200 vets.

Alcohol consumption among veterinary surgeons in the UK.

Background: Alcohol consumption can have both medical and occupational implications and may affect fitness to practise among veterinary surgeons (vets).

Aims: To investigate alcohol consumption and the prevalence and associations of 'at-risk' drinking among vets in the UK.

Methods: Alcohol consumption was measured using the Alcohol Use Disorders Identification Test alcohol consumption questions (AUDIT-C) embedded in a questionnaire which included measures of mental health and psychosocial working conditions, administered to a representative sample of 1796 vets.
