Conteúdo: 	Abstract: An experiment was conducted to investigate the effect of soybean meal (SBM) with different particle sizes included in mash diets on digestible energy, nutrient digestibility, and growth performance of broiler chickens. A total of 720 one-d-old male broiler chickens were assigned to 4 treatments with 9 replicates of 20 broiler chickens each in a completely randomized design and reared from d 0 to 42. The treatments consisted of the dietary inclusion of SBM with different particle sizes of 625, 775, 1,053, and 1,406 &#956;m. Coefficients of apparent ileal digestibility, growth performance variables, and carcass yield, and relative yield of parts were evaluated. The SBM particle size had a quadratic effect on crude protein digestibility and ileal digestible energy (P < 0.05). From d 0 to 21, feed intake was linearly reduced as SBM particle size increased, whereas WG increased and FCR improved quadratically (P < 0.05). From d 22 to 35, WG and FCR linearly improved (P < 0.05) as SBM particle size increased, but from d 36 to 42, growth performance was not affected. During the total experimental period (d 0 to 42), WG tended to increase (P = 0.06), and FCR decreased linearly (P < 0.05) as dietary SBM particle size increased, but feed intake was not affected. Carcass yield variables were not influenced by SBM particle size. As a conclusion, diets containing SBM with large particles fed to broiler chickens from d 0 to 42 result in similar crude protein digestibility and digestible energy as smaller SBM particles, but greater WG and better FCR can be obtained with large SBM particles.
