Parâmetros fisiológicos, produtivo e desempenho produtivo de codornas européias criadas em diferentes temperaturas

Abstract

Poultry breeding has been characterized by a growing increase in recent years.The development of this sector is due to the elevated genetic potential of theseanimals, the techniques of productive and reproductive control, in that currentlythe climatic variables have also contributed to the increase in productivity;the European quail (coturnix coturnix coturnix) has specificity for carcass yield.The project was developed in the Rural and Ambiental Constructions Laboratoryon the campus of the Federal University of Campo Grande , using 768 Europeanquail, in two distinct phases, counting with 384 birds in each phase, with twotemperatureees manipulated at 25.5 degrees C and 30.8 degrees C, having beenbred in confinement, where two sets of cages were used, each group having06 (six) cages with dimensions of 1 m of length x 0.50 of widthx 0.25 of height,using a floor without declivities, of galvanized material and anti-rust paint. The bioclimatic variables monitored were temperature of the environment, relataivehumidity of the environment, temperature of a black terrestial globe, temperatureof a humid bulb and temperature of a dry bulb. The experimental outline wasentirely randomized, with two treatments, two densities, three heights and sixrepetitions of the analyses per set of cages in an interval of 32 days. The experimentoccurred in a closed environment, practically without interference of external factors,being that the illumination was used in this period, aiming to induce the birdthe ingestion of water and ration in greater proportion, so that these same birdswould reach a better physiological and zootechnical development. This researchobjectivized the evolution of physiological parameters and the yield of birdcarcasses, maintained in a climatized environment.
