Résumé:
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.
