Abstract
    In order to determine the influence of light and compound feed upon production performance of laying quails was organized an experiment on 200 adult females aged 28 weeks of laying, in the post-peak period of laying. Were studied for 20 weeks 2 lighting programs, that is, a program M of continuous lighting and length photoperiod of 16 hours (16L+8N) and a E program of lighting with asymmetric hour intervals, with photoperiod duration of 16 hours (10L+2N+6L+6N). Also, there have been used two food recipes of compound feed with different nutritional parameters (M2 and E2, richer in protein, lysine and methionine in comparison with M1 and E1).
    As a result of the carried out research it was found that the average layingpercentage of batch E2 was higher with 9.50% compared with batch E1, and specific consumption was lower with 16.56%. Live weight was higher with 7.63% and average egg weight was higher with 4.17% at batch E2 compared with batch E1. At batch M2 the average percentage of laying was higher with 12.22% compared with the batch M1, and specific consumption was reduced by 11.00%. Live weight was higher with 20.32% and average egg weight was higher with 7.18% at batch M2 compared to batch M1.
    As a result of research we can say that the use of a program lighting with asymmetric hour intervals with photoperiod duration of 16 hours after the peak of laying lead to obtain enhancement productive performances on quails for production of eggs to consumption. The use of compound feed with higher protein levels and richer in amino acids lysine and methionine contributes to the improvement of the productive performance of laying quails during this period.
