Manejo de pintos de corte em diferentes tamanhos de materiais para o estímulo a alimentação

Abstract

The objective of the present work was to evaluate the performance of beef chicks in different sizes of feed materials. The difference in treatments was the length of the feeding role in the initial production phase, divided and evaluated in three treatments (T1: 60 cm, T2: 80 cm, and T3: 100 cm). In the commercial aviary, 1440 female chicks of the Cobb MX commercial line were separated in 18 boxes, totaling 80 chicks per box in the period of 1 to 7 days. On days 1, 4 and 7 a total of 9 birds / box were evaluated, and the yolk sac uptake was observed by the poultry organ, small and large intestine size. For all slaughtered birds of the box were evaluated the individual weight, box average weight and box feed conversion. The experiment was a completely randomized design, and the treatments were compared by analysis of variance and the differences analyzed by the Tukey test (5%). The data obtained were not affected by the treatments studied. The yolk sac absorption on the last day of the experiment was 0.11, 015 and 0.08 for T1, T2 and T3, respectively.
