Milk C18 polyunsaturated fatty acids from cows grazed on perennial ryegrass,tall fescue or timothy grass swards
Previous work at our institute has shown substantial variation in the degree of cell damage during ingestion and mastication of different grasses, resulting in differences in the release rate of nitrogen and lipid into rumen fluid (Kim et al.2008).These differences in the release rate of lipid may influence the extent of biohydrogenation in the rumen and consequently the C18 polyunsaturated fatty acid (PUFA) content of ruminant products.This study investigated the C18 PUFA of milk from cows grazing three contrasting grass species (perennial ryegrass, PRG ; tall fescue, TF ; and timothy, TIM) over two years.
