The objective of this work was to evaluate the effect of the administration of 20 mg of slow liberation bovine somatotropin (rBST) on the dry matter intake and on the digestibility coefficient of dry matter (MS), acid detergent fiber, crude protein, crude energy, nitrogen balance and the daily weight gain in lambs fed diets based on corn silage, sugar cane or hydrolyzed bagasse and concentrate. Twenty-four crossbred lambs, averaging 4-5 months of age and 22 + 2 kg LW, were […]

Effect of recombinant bovine somatotropin (rBST) on the performance of steers fed diets with different forages was evaluated. Forty crossbred steers, with average 360.2 kg LW and 30 months of age, were used. The animals were fed diets containing different forages (corn silage, sugarcane, corn silage + sugarcane and hydrolyzed sugarcane bagasse), and received an application of 320 mg rBST at every 28 days and were weighed at every 14 days during an experimental period of 84 days. The weight […]
