Avaliação de programas de alimentação para pintos de corte submetidos a jejum de 72 horas pós-eclosão

Abstract

The experiment was conducted in order to evaluate in practical condition the three feeding programme for broiler during 72 h of fast after heatching on pre-starter and starter phases. A total of 576 chickens Cobb-Avian Farms from seven to twenty days old were utilized. The feeding programs were: P1 = initial ration; P2 and P3 = pre-starter rations. P1 and P2 were similar to described in the Brazilian Tables (2000 and 2005), while P3 was the same program used in the poultry integrations. The experimente was in the a completely randomized design , with three treatments, each one with 12 portions and sixteen chickens per experimental unit. Accord to results at 7 days, the programs with pre-starter diets provided better (P < 0.05) feed conversion and averages of live weight of 12.46 and 15.17g, respectively, superiors to the program with initial ration. From 1 to 21 days, the feeding programs using pre-starter diets provided higher feed intake, live weight and weight gain. The results showed that the feeding programs with pre-starter diets improve the performance of broiler chicken up t
