Efeitos das variáveis meteorológicas na produtividade de aves poedeiras em dois sistemas de criação.

Abstract

Meteorological variables can affect the birds in a differentiated way, depending on rearing employee's system. Thus, this work had as objective to analyze the meteorological influences on the productive performance of laying hens housed in cage and in litter and the factors of larger relevance under the bioclimatic aspect in these two production systems. The analyses of the relationship between meteorological variables and production of the following day in cage and box demonstrated that the globe temperatures and of the dry air influenced the production of eggs of the birds in cages while these same variables didn't exercise influence for the birds in litter Already for the s birds housed in litter, the factor Maximum Relative Humidity was preponderant, affecting the production of eggs.
