Produção e qualidade de codornas japonesas (Coturnix Coturnix Japonica) submetidas a ambientes com diferentes espectros de luz.

Abstract

The Japanese quail ( Coturnix coturnix japonica ) is created for egg production . The research aimed to evaluate them as to stimuli of light spectra of white, red and blue , lamp type LED on production and egg quality . The project was developed in the Laboratory of Rural Buildings and Ambience - UFCG , using 387 of the japanese quail strain in laying phase . Bioclimatic variables were monitored air temperature , relative humidity and black globe temperature . The experimental design was a completely randomized design with three treatments and seven replications of the analysis in an interval of 14 days. Data were analyzed using Statistical Analysis System using the Tukey test ( P > 0.05) for comparison of means . The ambient relative humidity and air temperature were 26.7 ° C and 71.5 % respectively , the index of temperature and black globe ranged from 73.43 to 75.93 and radiant heat load varied from 441.62 to 470 , 74 , 96 . Feed intake was 29.08 g to 29.39 g and feed conversion of 401.39 g to 481.91 g per dozen eggs produced . The egg mass was 13.17 g in white , 12.99 and 12.96 g in red on blue . In the quality parameters of eggs ranged specific gravity of 1.08 g / ml in the white LED 1.07 g / ml in red , the haug unit was 89.38 89.15 in white and in red , the thickness of the shell was 0.34 mm in white and blue , and 0.33 mm in red and yolk index ranged from 0.45 in white and blue and 0.48 in red ; albumen weight was 8.13 g in white and 7 , 56g in red , the ( PG ) obtained in white was 3.64 g and 3.93 g in red ; shell weight was 1.10 g in red and blue was 1.02 g . The percentage of albumen , yolk and shell ranged from 62.50 to 60.05 , 28.86 to 31.18 , 8.32 to 8.64 respectively. The average values of resistance to longitudinal compression ranged from 12.83 to 15.14 N in white and white N 12.83 N; in resistance in the transverse direction was 14.93 N in white and red and blue in N 14.11 , we conclude that these birds can be created with these lamps , as there was no significant effect.
