Extract

Under Northern Ireland conditions, Keady et al. (2002, 2003) obtained positive responses in milk production to the inclusion of maize silage in grass silage-based diets. However, while the area of forage maize is increasing, there is considerable interest in the production of whole crop wheat as a forage for feeding to lactating dairy cows. The objective of the study was to examine the responses of lactating dairy cows to the inclusion of maize silage or fermented whole crop wheat silage in grass silage-based diets. Furthermore, the concentrate sparing effects of maize and wheat silage were determined. Finally the effect of protein level in the concentrate supplement when offered with the different forages, was evaluated.
