| Popis: | Eight broiler chicken diets were produced by using 2 pellet conditioning temperatures (65 and 85°C) and 4 pellet retention times in the conditioner (3, 9, 14, and 20 s). The effect of dietary treatments on pellet physical quality (intact pellet percentage, pellet hardness, pellet durability index, and water activity), growth performance (0 to 21 and 0 to 42 d), apparent ileal digestibility (CAID) of dry matter, crude protein and starch, and ileal digestible energy (IDE) was evaluated. 1,536 broiler chickens were randomly assigned to 8 dietary treatments (8 replicates of 24 chickens each). On d 42, 2 chickens per replicate were randomly selected for ileal content collection to evaluate dietary CAID and IDE. The greater conditioning temperature (85°C) improved pellet percentage, durability, and hardness (P |
