This study was carried out to evaluate the nitrogen balance, the urea concentrations in urine and plasma and the microbial protein synthesis in heifers fed diets containing sugar cane treated with calcium oxide. Twenty Holstein-zebu crossbred heifers, with average initial body weight of 200 kg were used, distributed in a completely randomized design, with four treatments and five repetitions. The animals were housed in covered individual stalls, with concrete floor, provided with individual concrete trough for feeding and automatic drinkers […]
