Desempenho de codornas da linhagem europeia (coturnix coturnix coturnix): uma análise comparativa entre os sexos

Abstract

Currently, the production of quail for cutting has been growing competitively in the consumer market. However, the productive characteristics of the lineage are not well established yet. In this sense, the objective through this work was to evaluate the zootechnical and economic performance, as well as the weight and yield of parts and organs between males and females of European Lineage quail (Coturnix coturnix coturnix). The experiment was conducted in the Coturniculture Sector of the Animal Science course, in the Institute of Agrarian and Technological Sciences at the Federal University of Mato Grosso, Rondonópolis Campus (ICAT/UFMT/CUR), from November to December, 2016. In this experiment it were used 360 European quails (Coturnix coturnix coturnix) distributed in a completely randomized design, with four repetitions each (n = 72). For this study it was isolated only the sex effect for data analysis. Thus, it were obtained zootechnical and economic indexes, as well as the weight and yield of parts and organs. According to the results it can be observed that there is an evident difference between the sexes of quail for the evaluated attributes. It can be noticed that zootechnical indexes are important to define the productivity of the lineage. On this wise, the production of females becomes more viable and interesting for this segment since females showed higher productive performance. Withal, it is necessary to establish breeding programs that prioritize the increase in carcass yield of female quails in order to promote greater consistency for the establishment of the lineage.
