Abstract

The marginal milk-production response to cereal grain supplementation of dairy cows grazing irrigated subterranean clover (Trifolium subterraneum L.) pasture in spring was investigated. We also determined whether the addition of a perennial ryegrass (Lolium perenne L.) straw supplement would improve that response. There were 8�replicated treatments in a factorial design with 2 amounts of cereal grain pellet [0 and 5.0 kg dry matter (DM)/cow.day] and 4 amounts of straw (0, 0.5, 1.0 and 2.0 kg DM/cow.day), 48 cows in total. Cows in all treatments grazed subterranean clover at an allowance (measured to ground level) of 19 kg DM/day. The barley and wheat pellet and straw had a neutral detergent ..
