Conteúdo: | An experiment was conducted to investigate the effects of the feed form and conditioning time of pelleted diets on pellet quality, broiler performance and nutrient digestibility during the starter phase. A total of 480 male Cobb broilers were distributed according to a completely randomized experimental design into six treatments with eight replicates each. Treatments consisted of a mash diet and five crumbled diets submitted to different conditioning times (zero, 60, 80, 100, or 120 seconds). The broilers fed pelleted diets submitted to steam conditioning presented higher feed intake and BW gain (P &#8804; 0.05), higher coefficient of ileal apparent digestibility (CIAD) of DM and CP, as well as higher ileal digestible energy (IDE) (P &#8804; 0.05) than those fed the mash diet. However, treatments did not influence FCR or starch digestibility (P > 0.05). Feed intake increased linearly (P &#8804; 0.05) with conditioning time while a quadratic response (P &#8804; 0.05) was noted for IDE. Conditioning time did not affect the amount of intact pellets or protein solubility (P > 0.05), but increased pellet durability index (P &#8804; 0.01), pellet hardness (P &#8804; 0.05), and water activity (P &#8804; 0.05). It was concluded that feed physical form and conditioning time influence the performance and nutrient digestibility in starter broilers. and that increasing conditioning times promote better pellet quality.
