In order to study the impact of a lighting program with asymmetric time intervals and different densities during the finishing period of youth quail for meat and slaughter results of youth male quail from population of Balotești in the period 28 – 49 days of growth was organized an experiment on a total of 300 male. At the age of 28 days were divided into cages for youth quail in two batches: the first batch consisting of 150 males has undergone a program of continuous photoperiod lighting with 16 hours per day (lots B and D), and the second batch has undergone a program of lighting with asymmetric time intervals with duration of 16 hours per day (10 hours light + 2 hours dark + 6 hours light + 6 hours dark) (lots A and C). Also, in the two batches was tested the effect of an experimental density of 250 cmp /head comparative with a control density of 125 cmp/head (lots B and D). From researches it is established that the best performances were recorded at the males from the batch A, who were subjected to a lighting program of 16 hours with asymmetric time intervals and was applied the experimental density of 250 cmp/head. The average live weight at the age of 49 days was with 6.47 % higher at batch B comparative with the batch A, with 9.21 % at batch C and with 13.71 % at batch D. Also in the batch A was registered the largest average carcass weight at age of 49 days (with 6.25 % from the batch B, with 11.02 % from the batch C, with 15.85 % from the batch D). Considering that have been registered superior performance at batch A is advisable when quail males are raised in the direction of meat production to be used a lighting program of 16 hours with asymmetric time intervals and a lower density of males in the cage because it significantly influence growth and slaughter performance.
