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

Com o experimento, avaliou-se uma condicao pratica de 72 h de jejum e o efeito de tres programas de alimentacao sobre o desempenho de 576 pintos da linhagem Cobb-Avian Farms aos sete e vinte um dias de idade. Os programas de alimentacao foram: P1 = racao inicial; P2 e P3 = racoes pre-iniciais. Os P1 e P2 foram aqueles constantes nas Tabelas Brasileiras (2000 e 2005), enquanto o P3 foi um programa utilizado nas integracoes avicolas. O delineamento experimental utilizado foi o inteiramente ao acaso, com tres tratamentos, cada um com 12 repeticoes e dezesseis aves por unidade experimental. Aos 7 dias, os programas com dietas pre-iniciais proporcionaram melhor conversao alimentar (P<0,05) e medias de peso vivo de 12,46 e 15,17g, respectivamente, superiores ao programa com racao inicial. De 1 a 21 dias, os programas de alimentacao utilizando dietas pre-iniciais proporcionaram maior consumo de racao, peso vivo e ganho de peso (P<0,05). Os resultados mostraram que os programas de alimentacao com dietas pre-iniciais melhoram o desempenho de pintos de corte ate 21 dias de idade submetidos a longos periodos de restricao alimentar pos-eclosao.
