Legumes are important constituents of ruminant diets and are a vital part of low input and organic systems. Previous studies have established the high intake characteristics and animal production potential of red clover silage. Studies with milk produced from cows fed on red clover silage was noted to have higher levels of polyunsaturated fatty acids (PUFA) but had a reduced shelf life which could be ameliorated by feeding additional vitamin E (Al-Mabruk et al., 2004). This study considered the effects of incremental inclusion of red clover silage in the diet of beef cattle on the fatty acid composition of the m. longissimus dorsi and meat quality.
