Extract

Recent developments in maize breeding and in agronomic practices, particularly the development of complete cover plastic mulch, have resulted in the possibility of consistently producing high yields of high starch maize silage in Northern Ireland. Recent studies (Keady et al., 2002, 2003) at this Institute have clearly illustrated that inclusion of maize silage, varying in maturity, consistently increases the performance of lactating dairy cows. Keady et al. (2002, 2003) concluded that the inclusion of maize silage in the diet of dairy cows had a potential concentrate sparing effect of up to 3 kg/cow/day. Currently there is considerable interest from beef producers of the potential effects of the inclusion of either maize or whole crop wheat (WCW) silages on the performance of beef cattle. The objective of the present study was to evaluate the effects of including maize and WCW silages in grass silage-based diets on food intake and animal performance of beef cattle offered two levels of concentrate.
