Dr. Gaston Federico Alfaro: Rumen-Protected Nutrients | Ep. 20
In this episode, I hosted Dr. Gaston Alfaro, a professor and researcher at Universidad Nacional de Córdoba. We delved into Dr. Alfaro's substantial work on rumen-protecting nutrients, including choline, methionine, and niacin. Our discussion was enriched by his hands-on experience in Florida, Alabama, Nebraska, and currently in Cordoba. We also explored Dr. Alfaro's ongoing research on residual feed intake at his experimental station, an intriguing project aimed at identifying animals that need less feed for the same output.
"Residual feed intake assesses the feed efficiency of different genetic lines by comparing how much feed each line needs to reach the same weight, reflecting inherent differences in their physiology and nutrient absorption."
