An experiment was conducted to evaluate the growth performance, carcass characteristics and blood metabolites of broiler chickens fed diets formulated on total or digestible amino acids (TAA or DAA) basis with bovine bile salts powder (BBSP) and different levels of soybean oil (SO). A total of two hundred and forty 1-day old chicks were randomly allocated to eight treatments with three replicates of 10 birds. The experiment was carried out in a completely randomized design with 2×2×2 factorial arrangement, including two levels of BBSP, two levels of SO and two methods of amino acids balance (TAA or DAA) in diets. The results showed that main effects of BBSP, SO and feed formulation procedures (TAA or DAA) had no effects on all growth performance parameters (P > 0.05). Carcass traits, except for thigh weight, were not influenced by all dietary treatments (P > 0.05). The birds fed diets with BBSP had a greater thigh weight than the other group. The results of blood biochemical metabolites indicated that serum triglyceride was affected by amino acid formulation method (P < 0.05). In contrast, the other serum metabolites did not alter by dietary treatments (P > 0.05). The results indicated that liver enzymes activities including alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were not influenced by dietary BBSP and SO (P > 0.05). However, AST activity was affected by amino acids formulation procedure (P < 0.05). In conclusion, the addition of bile salts (BBSP), different inclusion rate of SO and amino acids balance method (DAA or TAA) in broiler diets had no negative effects on all growth performance and carcass traits.
