Id# 09-35 Duration of Regrowth of Ryegrass (lolium Perenne) Swards: Effects on Rumen Fermentation of Lactating Dairy Cows


The relative importance of duration of sward regrowth and rumen fill and fermentation on the control of grazing time and intake rate during the first grazing session of the day were studied. Four lactating dairy cows were allowed to graze ryegrass (Lolium perenne) swards, with five different regrowth periods after mowing (6, 9, 16, 22 and 30 d). The cows… (More)
