Desempenho de frangos de corte produzidos em sistema convencional, climatizado e dark house

Abstract

Poultry facilities play a fundamental role in ensuring animal thermal comfort and in ensuring that broilers can express their best productive characteristics. However, in Brazil there are several models of facilities for the production of broilers. In this context, the objective of this study was to evaluate the zootechnical performance of broiler chickens produced in a Conventional, Climatized and Dark House system in farmers located in the Passo Fundo-RS micro-region. Therefore, data regarding the feed conversion ratio, mortality and daily gain of weight were collected from four lots of two farmers of each system, totalizing 8 replications per treatment, through a randomized block design, where it was also objectified to evaluate the performance among the farmers that use the same system. After the analysis of the data, it can be observed that for the feed conversion ratio and mortality the Climatized and the Dark House systems were equivalent among each other, but superior when compared to the Conventional system. As for the daily gain of weight, the climatized system showed a better response when compared to the other systems. Nevertheless, among the farmers working with the same system, there was no difference in the broilers zootechnical indexes whatsoever. These data allow us to conclude that Climatized and Dark House type facilities which have a higher degree of technology have shown higher productive efficiency when faced with the Conventional system.
