51 - Dr. Jinsu Hong: Optimizing pig performance and economics with cDDGS

swine nutrition blackbelt Jan 26, 2023

Corn dried distillers grains with solubles (cDDGS) are a byproduct of biofuel and alcohol production. In pig feed, cDDGS are commonly used, since they are readily available and contain protein, fiber, and unsaturated fatty acids. But what are the best ways to use them in pig diets, and what are the limits? In this episode, I talk with Dr. Jisun Hong about a study he conducted that evaluated the effects of feeding swine with diets which included different levels of cDDGS. He also discusses the adjusted ratios, from branched-chain amino acids to lysine, aimed at growth performance, blood amino acid profile, carcass traits, and economics.

Favorite book, movie or TV series: I have recently watched the movie Avatar 2. As a person who does swine research, I've been thinking about how we should approach and think about pigs in the future (regarding welfare, sustainability, etc).
