Topic: Relying on evidence from published and ongoing research, this presentation will examine the key drivers of success in rural veterinary practice, emphasizing practical strategies to improve career sustainability, financial performance, and personal well-being.

While rural veterinarians often perceive a wage gap compared to urban counterparts, recent survey data suggest that this gap is more pronounced for associate veterinarians than owners. While salary undoubtedly matters, factors such as practice atmosphere, mentorship, caseload variety, and geographic location also play a role in both recruitment and retention.

A central challenge highlighted is the burden of emergency duty, which is a leading contributor to burnout and a common reason veterinarians leave rural practice.

The presentation outlines actionable approaches to mitigate this burden, including clearly defining what

Topic: Reviewing the importance of trace minerals in reproductive and immune function. Evaluating trace mineral levels in herds to develop plans of supplementation with emphasis on controlling antagonism.

constitutes an emergency, establishing structured oncall protocols, setting client expectations, and leveraging team-based or regional collaborations to distribute workload. Emphasis is placed on reinforcing professional boundaries and improving work-life integration.

Financial success is framed as a function of management competency rather than revenue alone. Skills such as financial literacy, strategic planning, leadership, and effective delegation are identified as critical for practice growth and sustainability.

The presentation also addresses mental health, drawing on recent wellbeing studies indicating a measurable prevalence of psychological distress within the profession. Protective factors include fostering selfefficacy, optimism, and proactive coping strategies, alongside systemic improvements in workload and compensation.

Ultimately, the session provides a data-driven yet pragmatic framework for rural veterinarians to enhance job satisfaction, reduce burnout, and build resilient, highperforming practices.

Topic: Bovine viral diarrhea virus (BVDV) presents an active threat to the beef cattle industry through premature culling, reproductive losses, morbidity, and mortality. Vaccination and testing are two hallmarks of prevention and control of BVDV through the cattle industry. Understanding the role of timely vaccination of calves and replacement heifers and the effects on sustained humoral and cell-mediated immunity, reproduction and herd longevity are critical. To determine long term effects of preventative vaccination, heifer calves born in 2014 received a modified-live viral (Bovi-shield Gold) vaccine at 3 months of age, followed by a vaccination at 8 months of age of either a modifiedlive viral vaccine or killed viral (CattleMaster) vaccine beginning their annual revaccination, and heifer calves born in 2015 received only a modified-live viral vaccine or killed viral vaccine against BVDV at 3 months which was sustained throughout their annual revaccination for their lifetime in the herd. Similar reproductive longevity and calf performance was observed throughout the lifetime of the cattle in each treatment group. Cows receiving an initial modified-live viral vaccine followed by a killed viral vaccine had greater cell mediated responses than cows receiving only a killed viral or only a modified live viral vaccine. This may provide an advantage when cattle are exposed to BVDV in the field without harming reproduction.
