This work was carried to evaluate the effect of diferents of broiler litter inclusion (approximately 0, 10, 20 and 30%, in dry matter base) with 45% forage cactus associaded to sugar cane bagasse, urea and cotonsead meal, in total diet form, on nutrient intake and milk yield and to evaluate the time necessary to adaptation of the animals to diets. Eigth lactating 5/8 crossbred Holstein/Gir cows with 420 kg of LW and production of 15 kg/day, were assigned to tratament sequences in a replicated 4X4 latin square with four periods, four animals and four levels of broiler chiken in the ration. The intakes of dry matter, neutral detergent fiber, acid detergent fiber, total carbohydrates, nonfiber carbohydrates, and organic matter, showed significant quadratic answer. However, mineral matter and ether extrat had linear increase. The milk yeld, milk yeld correct for 4% of fat, fat level, fat yield and alimentar eficiency showed no significant diference. The adaptation period was complete within seven days.
