Performance and Carcass Traits of Broiler Chickens Reared on LEDs vis-a-vis CFL as a Growth Promotor

The present study was conducted to compare the performance of broiler reared under two different light sources and three different light colours. For this purpose, 120, two-week-old IBL-80 (Indian Broiler Ludhiana-80) broiler chicks were randomly distributed in four different treatment groups viz. T_LEDB-G (first 2 wks, blue LED then switched to green LED for the next 2 wks), T_LEDG-B (first 2 wks, green LED then switch to blue LED for the next 2 wks), T_LEDW (White LED) and T_CFL (CFL light; Control) with 3 replications and 10 birds in each experimental unit was applied. The effects of different lights on performance (BW, BWG and FCR), carcass traits and its economic impact on broiler chickens were investigated in the present study. The results show that performance and carcass traits of broiler birds of blue-green and green blue LED light group was at par to that of CFL group whereas benefit cost ratio of birds of T_LEDB-G (1.13) was found highest among different treatment groups. Therefore, use of a combination of monochromatic Blue-Green or Green-Blue LED light could be a better alternative source of light than CFL light in terms of birds’ performance, economics and energy saving.
