Resumo: | This study aimed at evaluating live performance and carcass yield of broilers fed vegetarian diets or containing different animal byproduct meals after 8 days of age. In the experiment, 1080 one-day-old male chicks were distributed in a completely randomized experimental design with 6 treatments with 6 replicates. Diets were based on corn and soybean meal, and included or not animal meals, maintaining constant levels of minerals (calcium, phosphorus, and sodium) and amino acids (methionine, cystine, lysine, and threonine), The following treatments were applied: T1. Control (corn and soybean diet); T2. Inclusion of 5% meat and bone meal (MBM); T3. Inclusion of 5% blood meal (BM); T4. Inclusion of 5% feather meal (FM); T5. Inclusion of 5% poultry offal meal (OM); T6. Combination of meat and bone meal, feather meal, offal meal, and blood meal. Broiler weight gain, feed intake, feed conversion, livability and carcass yield were evaluated. At 35 days of age, it was verified that the combination of the four animal meals compromised weight gain. Broiler performance at 42 days of age was influenced by treatments, and the worst weight gain and true feed conversion were observed in birds fed diets with the combination of the four animal meals. The inclusion of 5% BM negatively affected the weight gain. It is concluded that MBM, FM, and OM inclusion can be individually used with no negative influence on broiler performance or carcass yield. In addition, it reduces feed costs.
