  We investigated the effect of LED lamps and incandescent lamp bulbs on the productivity and slaughter quality of Pharaoh breed meat quaility. LED lamps had power output of 16 W, luminous flux of 1400 Lm, and color temperature of 4200 K. Incandescent lamp bulbs had power output of 40 W, luminous flux of 500 Lm, and color temperature of 2300-2900 K. From the 6th day of rearing the light, the intensity was 10-15 Lk within the level of live weight. We established a positive influence of LED lamps on quail slaughter qualities. The quails of experimental group (with LED lamps) had the advantages in terms of live weight (it was higher by 21.5 g or 8.23%, P> 0.999), the gains, feed conversion ratio (higher by 0.2 kg, or 5, 08%), quail liveability (higher by 4%). According to the results of the control slaughter, we admited a striking privilege in the level of slaughter weight and the eviscerated carcass of the poultry of the experimental group. The difference between groups is significant (P> 0.95…0.999). The advantages of the quails from experimental group towards the output of thigh muscles (higher by 0.02%), the drumstick muscles (0.12%), and the liver (by 1.02%) were obvious. The anatomical indices confirmed the influence of indoor lighting source on quali slaughter quality, i.e. the index of carcass food part and leg meat from experimental group were higher, the same was true with the indices of muscle and muscle breast of the quail of the control group with incandescent lamp bulbs.
