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...

An Integrated Approach to Improve While Herd Pig Survivability
March 4, 2023By Dr. Kara Stewart
Pre-weaning survival in US herds ranges from 80-90% with the majority of the death loss occurring in the first three days after birth from crushing from the dam. Risk factors for mortality are low...
