Extract

In previous research grazing dairy cows showed no response to whole-crop barley silage (WCB) cut at different stages of growth, but the crop yield and quality, and DM losses were optimised at 350 to 450 g DM/Kg (early to hard dough) (Hargreaves and Leaver, 1992). However tha effect of herbage availability on the response to WCB supplementation is not known, therefore the objective of this study was to examine this effect during mid to late summer.

Winter barley (var. Puffin) was harvested on 16th July at 380 g DM/Kg (soft dough) and a yield of 14 t DM/ha. The chopped material was stored in a bunker silo.
