COMPORTAMENTO DE CODORNAS JAPONESAS SUBMETIDAS A DIFERENTES DENSIDADES ALIADAS A DEBICAGEM

It was evaluates behavior of Japanese quails (Coturnix coturnix japonica) submitted to different densities combined with the nozzle cutting procedure. The experiment was developed into the experimental farm, in quail culture the Federal University of Mato Grosso, lasting 63 days divided into three periods of 21 days each. There were used 196 quails layer at 38 weeks of age. The quails were divided into 2 x 2 factorial scheme (beak trimming and not beak trimming; low density and high density of accommodation), with seven repetitions. The parameters were submitted to analysis of variance the 5% probability by Tukey test. The birds housed in high densities had less time in idleness, less comfort, less interaction with feathers and less time eating. Birds in higher density had increased panting and increased aggressiveness. The birds debicadas not and with high density had a higher occurrence of aggressive behaviors and signs of stress.
