Abstract

1. Experiments were conducted to investigate nitrogen metabolism of the dairy cow in relation to the control of the voluntary intake of grass silage and its utilization for milk production. Two aspects were considered: the effects of ammonia absorption from the rumen and the effects of changes in the post-ruminal supply of proteins and amino acids. In all experiments, dairy cows were given ad libitum access to grass silage and a fixed level of supplement based on barley and, where necessary, soyabean meal to give a total dietary CP concentration of 140-150 g/kg DM.
