In the present work we aimed to compare intake, performance, feed efficiency and carcass traits of cattle from three genetic groups (GG) fed two concentrate levels in the diet. Forty-eight steers (16 Nellore, 16 Nellore-Red Angus and 16 Nellore-Simmental) were used. Twelve steers were slaughtered at the beginning of experiment as a reference group and for the remaining 36 animals, the concentrate mixture of the ration was offered as 1 and 2% of body weight basis in a 3 × […]

Aiming to evaluate the spray-dried plasma levels (BP) in diets for piglets weaned at 28 days of age, an experiment with 128 piglets with initial body weight of 7.635 ± 0.103 kg was conducted and allocated in a experimental block design composed of four treatments, eight replicates and four animals per replicate. The treatments used were: diets with dried milk (DM) and without spray-dried plasma (BP) from 29 to 42 days of age; diets with DM and 2.8% of BP […]
