Extract

In a previous experiment in this series fodder beet was substituted for a major proportion of the concentrate supplement in a high concentrate diet with lactating dairy cows. The diets were offered at a restricted level of feeding and a major depression in the concentration of fat in milk was obtained with the concentrate diet (McIlmoyle et al., 2001). It was the objective of the present experiment to examine the effects of diet composition, namely fodder beet versus concentrate in a silage based diet and level of feeding, namely restricted versus ad libitum feeding on rumen fermentation.
