Seminar #7: Swine Health through Nutrition: Feeding the Pig in a Changing World
Seminar chair: Alexander Hintz

Swine veterinarians have long been focused on the health of the pig. In our changing environment, we need to be aware of nontraditional and novel interventions via nutrition to maximize pig health. With that, we also need a good understanding of basic nutrition principles. This seminar will provide the basics on feeding our highly prolific pigs. You'll learn how to analyze data in feed trials as you begin to explore alternative interventions. In addition, you'll hear from experts in multiple industries about the portfolio of nutritional interventions available to improve animal health.

Seminar co-chairs: Jeremy Pittman and Angela Supple

The "Swine Medicine for Students" seminar's main goal is to supplement veterinary students and recent graduates with practical knowledge and tools they will need and use in practice. This year's topic will center on the use of water-soluble antibiotics: products, common issues, and the dreaded calculations of how to mix water meds! The first portion of the seminar will be teaching and training on water meds, followed after the break by interactive, real-world cases, when groups will use their knowledge to select the appropriate antibiotic and calculate the proper mixing/dosage rate for the cases.

Values and behavior drive culture. It is one thing for a veterinary leader to envision a value. It is another to make sure it is living. In this session, veterinary leaders will share their experiences as leaders working to create living cultures on teams in their business, on farm, and/or with fellow veterinarians. Speakers will share what worked, what didn't, and what they would do differently the next time around. From handling challenging situations to reducing polarization to leading a culture of diversity, equity, inclusion, and wellness, learn from the experience of your colleagues to sharpen your ability to lead a living culture.
