The objective of this work was to evaluate the effect of association of forage cactus to sugar cane bagasse and urea on nitrogenous compounds balance and microbial protein synthesis in milk heifers supplemented or not. Twenty-five Holstein-Gir crossbred heifers with average of 227 kg of LW were used, kept in feedlot system and assigned to a randomized block design, established in accordance with the weight of animals. The control ration was composed of 64.0% of forage cactus, 30.0% of sugar […]

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 […]
