Extract

Previous studies (Castejon and Leaver, 1990) with heifers of 350 kg liveweight showed whole crop wheat (WCW) treated with 40 kg urea/t DM had a DOMD of 654 g/kg, and 8% of grain in the crop was excreted in the faeces. Morgan and Campling (1978) have shown that age of animal influences the digestibility of cereal grains.

The objective of the present trial was to examine the intake, digestibility and liveweight gain of three sizes of heifer with and without supplementation.
