The objective of this work by evaluating consumption, production and processing of milk from cows fed diets containing increasing levels of urea.8 cows were used 7/8 Holstein / Gir Dairy in two 4x4 Latin squares, each square composed of four diets, four cows and four experimental periods.Diets were formulated to be isonitrogenous, and as forage silage cane sugar.Treatments consisted of increasing levels of urea in place of soybean meal (0, 0.58, 1.17, 1.75% of the total DM diet).The intake of dry matter and neutral detergent fiber were not affected by increasing levels of urea.However, crude protein and ether extract decreased linearly with increasing levels of urea.The consumption of non-fiber carbohydrates presented cubic behavior in relation to the levels of urea.The production of milk (27 kg / day), the physico-chemical composition of milk and Minas fresh cheese as well as cheese yield was not affected by the inclusion of urea in the diet of cows.Therefore, it is concluded that, for diets of lactating cows, the sugar cane silage basedr, with forage:concentrate ratio 45:55, the urea can be added up to 1.75% of total dry matter without harming consumption, income, production, physico-chemical composition of milk and Minas cheese.
