dc.description.abstractThe study was conducted to evaluate the effect of different LED monochromatic light (green, λ= 560 nm; blue, λ= 480 nm; red, λ= 660 nm) on growth of broiler chicken in comparison with white LED light and incandescent bulb light. Relative expression of IGF-1 and MSTN gene in breast muscle, muscle fibre diameter of breast and thigh muscle of 17, 24 and 31 day old broiler chicks as well as weekly body weight and body weight gain was used to assess the growth. The study showed that on day 17 the birds under green light had more IGF-1 and MSTN expression, followed by those under blue light. A better breast and thigh muscle fibre diameter was also observed in birds under green and blue light. On day 24 and 31 birds reared under blue light showed a better breast and thigh muscle fibre diameter, IGF-1 and MSTN gene expression than others. However, on day 31, they had MSTN expression similar to other birds except the birds under red light. Though changes in IGF-1 expression were noticed at different ages in birds reared under blue, green, red, white LED and incandescent light; there were corresponding changes in MSTN expression which followed the same pattern. Light colour effected the growth and expression of MSTN and IGF-1 genes, breast and thigh muscle fibre diameter, body weight and body weight gain. In the early period up to day 17, green light was most stimulatory to growth, breast and thigh muscle fibre diameter and the expression of MSTN and IGF-1 genes under study. After day 17 up to day 31, blue light resulted in maximum expression of MSTN and IGF-1 genes, breast and thigh muscle fibre diameter and growth. Chicken can be reared under green light up to day 17 and then afterwards under blue light for more growth during same period. Further studies can be conducted to evaluate the meat quality parameters and different cuts of meat, feathering, lighting management practices, welfare, blood physiological and biochemical variables and the functional development of the eye and brain. At fourth week of age birds under blue light had a better body weight gain followed by birds under green light. At fifth week of age birds under blue light had a significantly high body weight gain when compared to all other groups. The study revealed that blue and green monochromatic LED light is better for growth of broiler chicken than other lights used.en_US
