The objective of this research were to detect how many days where necessary to animals to adapt to diets, to measure intake and milk production; also, to evaluate the effect of four levels of crude protein in the non protein nitrogen (NPN) based compounds (2,22; 4,18; 5,96 e 8,09%) on the milk composition and production, the intake and apparent digestibilities of dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), ether extract (EE), total carbohydrates (CHOT) and crude protein […]
Keywords: digestibility; intake; lactating cows; milk production; non protein nitrogen (NPN) compounds
