Asad Ali Khaskheli
Present review was performed in order to understand the influence of photoperiod and light intensity on Coturnix japonica. Different literatures were reviewed regarding egg production, behaviour, body weight, feed intake, feed conversion ratio, carcass weight, egg quality with respect to photoperiods and intensities. It was noticed from the reviewed studies that light intensity of 80 and 20 luxes for 8 hours during growing period and 240 and 60 luxes for 16 hours during laying period results 194.85±4.46, 191.42±2.87 feed intake, 201.00±13.82, 210±15.1 weekly weight gain. The better feed conversion ratio remains (1.03) with light intensity of 80 and 20 luxes for 8 hours during growing period. Carcass weight remains as 98.33±8.33 and 99.56±5.44, dressing percentage 50.46% and 52.01%, egg production percent 50.11 and 48.81, egg length 32.15±0.54 and 32.12±0.35, egg width 24.87±0.22 and 23.75±0.31, egg weight 9±0.44 and 9±0.54, 11.2±0.73 when light intensity of 80 and 20 luxes for 8 hours during growing period and 240 and 60 luxes for 16 hours during laying period is provided. In conclusion Coturnix japonica raised on 80 luxes for 08 hours light intensity during growing period and 240 luxes for 16 hours light intensity in laying period results better FCR and feed intake in cage system. While Coturnix japonica reared with 5 luxes for 16 hours photoperiod during growing period and 15 luxes for 20 hours photoperiod in laying period demonstrate better egg production and behaviour.
