Extract

The choice of optimal stage of maturity at harvest for whole-crop wheat remains controversial. Problems of aerobic stability with crops harvested and ensiled at an early stage led to increased interest in harvesting at a later stage and preserving the crop with urea. However recent studies have shown low starch and fibre digestibility with such crops when fed to lactating dairy cows (Sutton et al.,1991). The purpose of the present work was to determine the effect of harvesting wheat at three stages of maturity on the in situ degradability of dry matter (DM), neutral detergent fibre (NDF) and starch.
