The experiment was conducted in the Animal Production Center (NUPRAN) at the Masters Course in Veterinary Sciences of the Agricultural and Environmental Sciences Sector of UNICENTRO, in Guarapuava-PR. The objective was to evaluate the productive performance, the ingestive behavior, the apparent digestibility of the diet and the carcass characteristics of beef cattle finished in feedlot under the effect of using antimicrobial stabilizers in the diet and of fractioning or not the diet feeding: T1 - diet without stabilizer fed twice a day-1; T2 - diet without stabilizer fed once a day-1; T3 - diet with stabilizer fed twice a day-1; T4 - diet with stabilizer fed once a day-1. The diets were formulated and consisted of a mixture of 40% corn silage and 60% concentrate. The experimental design was entirely randomized blocks, in a 2 x 2 factorial scheme, consisting of four treatments and four replicates each, where each replicate was represented by a stall with two animals. The experiment used 32 whole, ½-blood Angus calves from the same herd, with an average age of 11 months and an average initial live weight of 350 kg. The use of chemical stabilizers, as well as the fractioning of the diet twice a day favored the productive performance of the confined animals, increasing MSM, DMS, and carcass production.
