Extract

Wahed et al. (1990) showed that the intakes of barley straw in untreated, long form, were increased by 0.35 and 0.57 when the ad libitum amounts offered to sheep were increased from 18 to 54 and 90 g dry matter (DM)/kg live weight (M) daily, respectively. The quality (in vitro digestibility) of straw consumed also improved with offer rate. There is no such information available for oat straw. In view of the latter, and the increasing use of oats in human foods and the greater availability of oat straw for feeding, the present experiment investigated whether the intake of oat straw by sheep could be increased by increasing the amount offered.
