Extract

Both breed and feeding system can affect the composition of fat depots in cattle. Furthermore, carcass fat colour may be influenced by forage-based diets due to the deposition of pigments, but also by changes in texture and firmness because of differences in the fatty acid (FA) profile. The objective of this work was to study the relationship between colour and FA profile of subcutaneous (SC) fat depending on breed and feeding systems in yearling bulls.
