Previous studies (Moorbyet al, 1994) have shown that supplementing grass silage with undegradable protein (UDP) during the dry period can lead to increased yields of milk protein and lactose. These studies have often involved restriction of forage intake through limitation of access time and the feeding of straw. This experiment was conducted to assess the effect of UDP supplementation withad libitumaccess to grass silage as well as the effects of restricting forage intakes by including straw in the diets of dry cows.
