چکیده

Functional additives, such as autolyzed yeasts, have been used to achieve greater production efficiency and animal health. These compounds are also alternatives the use of performance-enhancing antimicrobials. The objective was evaluate productive performance, ingestive behavior, apparent digestibility feed DM carcass characteristics beef steers finished in feedlot receiving yeasts diet. experimental design randomized blocks, consisting three treatments six repetitions, where each repetition represented by a stall with two animals. 36 bulls, ½ Angus × Nelore blood, from same herd, an average age 11 months body weight ± 330 kg were used.The follows: CON - yeast-free diet; Y4 yeast diet (4 g day-1) Y7 (7 day-1). product is functional ingredient containing Saccharomyces cerevisiae. inclusion resulted daily gain better conversion initial phase. diets superior control diet, its did not interfere behavior.
