The value of malt distillers’ grains ensiled with molassed sugar beet pellets as a feed for dairy cows

In one experiment twenty-four Holstein Friesian cows, average 43 d post-partum, were used in a changeover design experiment to evaluate the replacement of a cereal-based concentrate supplement (C) by an ensiled mixture (MGBP) of malt distillers’ grains and molassed sugar beet pellets. The cows were offered grass silage ad libitum [dry matter (DM) content 170 g kg )1 , crude protein (CP) concentration 160 g kg DM )1 , metabolizable energy (ME) concentration 10AE 9M J kg DM )1 ] and
