Pork quality is an important attribute for niche pork markets. Diet and genetics are two important factors influencing growth performance and carcass characteristics of finishing pigs. It is well documented that matching dietary amino acids with genetic potential for growth is a sound strategy to maximize lean growth. The impact of underfeeding lysine and other amino acids on carcass quality attributes is less certain. The purpose of this study was to compare growth performance and carcass characteristics of market pigs fed reduced lysine diets in bedded hoop barns with the intended goal of improving intramuscular fat. This article reports the results from four trials conducted March 2015 through January 2016.
