We all know about the importance of calcium and phosphorus in the diet, but can we be more precise with our feeding techniques? In this episode with Laura and Dr. Tom Crenshaw, they discuss Tom’s work by diving deeper into the cation and anion balance as well as certain instances where we may be over-feeding calcium or phosphorous without knowing it.

What you will learn:

1. Current Ca:P ratios in the industry

2. Can the same ratio be used for all sows?

3. Cation-anion balance

4. Potassium levels in the diet

5. Key Points

Meet the guest: Dr. Tom Crenshaw is a professor in the Department of Animal Sciences at the University of Wisconsin-Madison. He received Ph.D. and M.S. degrees at the University of Nebraska in Swine Nutrition and a B.S. degree in Animal Sciences at the University of Tennessee-Martin. Two main themes have persisted throughout Dr. Crenshaw’s research in mineral nutrition related to skeleton growth. These include the roles of cation-anion balance and nutritional factors which enhance bone integrity. His research has allowed strong ties with researchers in academia and the commercial swine industry, and importantly, the projects have provided opportunities to train both graduate and undergraduate students.
