ÍNDICES PRODUTIVOS EM DIFERENTES LINHAGENS, SEXO E SISTEMA DE PRODUÇÃO EM FRANGOS DE CORTE

Abstract

The objective of this work was to evaluate the effect of broiler production on sex, lineage and production system, in relation to average daily gain, average weight, consumption, feed conversion, mortality and production efficiency index. the data obtained for the experiment were provided by Qualitti Alimentos, referring to 6 production lots. In total, 6 sheds were used, with the Dark House system and 6 with the conventional system. The lineages evaluated were Cobb and Hubbard, separated according to sex, male, female and mixed animals (housing with males and females). For the statistical analysis of the variables studied (average daily gain, mean weight, consumption, feed conversion, mortality, productive efficiency index, production factor), the analysis of variance of the data was performed through the SAS UNIVERSITY statistical program (2017) , through the PROC GLM procedures, at the 5% level of significance. To obtain the differences between the means, the Tukey test was used at 5% probability.
