Avaliação do efeito dos diferentes programas de alimentação no desempenho produtivo de frangos de corte

Abstract

The present work was carried out at the Abrantes Castigo production unit, in the district of Vilankulo. Its general objective was to evaluate the effect of the different programs of feeding (3 and 2 phases) on broiler production performance. were used 200 Coob 500 one-day-old chicks, specialized for cutting up to 35 days of age age and distributed in four experimental units with 6 m 2 each. Was used completely randomized design with two replications and 50 chickens per unit experimental, the treatments were three-phase feeding programs (A0, A1 and A2) and the two phases (A1 and A2). The productive performance parameters were evaluated. To the Data analysis used descriptive statistical techniques and for the comparison of the effect of feeding programs on productive performance, the F (ANOVA) submitted to the t-student test, with a significance level of 5%. The software used to obtain the statistical calculations was ASSISTAT Version 7.7. In this way, there was an effect significant (P˂ 0.05) of broiler feeding programs on parameters productive. The three-phase program (inclusion of pre-starter diet) provided results significant (P˂ 0.05) for weight gain, average daily gain, and feed conversion. No significant effect (P> 0.05) was observed for feed intake, average daily intake and the viability rate. It is recommended to use three-phase feeding programs, that include pre-starter diet as it provided better productive performance until the end in comparison to two-phase program (TRADUÇÃO NOSSA)
