Every Gut Is Different

“Cows spilled their guts for a unique discovery.” A few years ago, the USDA’s Paul Weimer ran a simple, but elegant trial that revealed how distinct one cow is from another.

Researchers at Utah State University sent three forage sam-ples to twelve laboratories for three months. Results were not encouraging. Relative feed value (RFV) for…
