Summary and Implications

The goal of this experiment was to determine the impact of low and high energy diets on the meat quality of animals selected for divergent residual feed intake (RFI). Low RFI (efficient) and high RFI (less efficient) pigs were fed either a high energy, low fiber (HELF) or low energy, high fiber (LEHF) diet. Diet had little impact on meat quality. Selection for low RFI animals resulted in loins with greater water holding capacity and sensory juiciness. High RFI animals have loins with greater percent lipid, color and marbling scores, and a* values (are more red in color). It is unlikely that marbling and color differences are large enough to be detected by the consumer.
