The objective of this research was to evaluate the effect of increasing levels of CP in the total DM of diet (11.5, 13.0, 14.5 and 16.0%) on the intakes and the total digestibility of nutrients and the milk production and composition of dairy cows in initial third of lactation. The research was constituted by four experimental periods of 15 days each, seven for adaptation of the animals to the diet and eight for data collection. Eight cows, individually fed, were […]
