Improving feed efficiency of growing to finishing pigs fed high DDGS containing diet with different branched-chain amino acids to lysine ratio
March 4, 2023By Ryan Samuel
Corn distillers dried grains with solubles (cDDGS) can replace portions of corn and soybean meal (SBM) in swine diets. However, high dietary inclusions of cDDGS can reduce growth performance, which...

Improving performance of finishing pigs with supplemental Val, Ile, and Trp: Validating a meta-analysis model
November 24, 2021By Jason Woodworth
Branched-chain amino acids (BCAA) are a collective group of amino acids (AA) made up of Leucine (Leu), Valine (Val), and Isoleucine (Ile). These three AA all share the first steps of catabolism, and...
