Feed Nutritional Effects on Carcass Composition

The effects of nutritional treatments on carcass composition, within normal practical limits, are relatively small. Feeding at a high level (ad libitum) to the same body weight increases fat compared with restricted feeding, and grass-based diets produce fatter carcasses than grain-based (concentrate) diets, associated with a reduction in available protein. However, these nutritional effects are relatively small compared with breed effects. Weight is an important determinant of carcass composition, with fatness increasing significantly at higher carcass weights.
