Summary and Implications
The goal of this experiment was to determine the impact of high and low energy diets on adipose tissue quality of animals selected for divergent residual feed intake (RFI). Pigs of a low RFI (efficient) line and high RFI (less efficient) line were placed on either a high energy, low fiber (HELF) diet or a low energy, high fiber (LEHF) diet. Line had no impact on adipose tissue color or iodine value. Regardless of line, feeding a diet low in energy resulted in adipose tissue with a darker colored and increased iodine value, when compared to adipose tissue from animals fed a high energy diet.
