Extract

Cattle fed grass silage generally have higher fatrprotein ratios than cattle fed other forage-based diets. This has been shown to be at least partly due to impaired protein accretion (Gill et al., 1987). It is however unclear whether differences in fat accretion are also responsible. This experiment was designed to compare rates of whole body fat metabolism, rates of fat deposition and carcass composition between grass silage and dried grass diets fed over a range of ME intakes.
