Impact of blue and green monochromatic light in comparison to white LED on the stress reaction and mortality rate of broiler chickens

Abstract

The present experiment was conducted to investigate the impact of blue and green monochromatic light in comparison to white LED on the stress reaction and mortality rate of broiler chickens. For a period of 42 days study two hundred forty day old Vencobb 400 straight run commercial broiler chicks were randomly divided into three groups with 2 replicates of 40 in each at the poultry unit of livestock farm complex, College of veterinary sciences and animal husbandry, A.N.D.U.A.T. Kumarganj, Ayodhya, (U.P). In first green-blue group (TGB), the birds were kept on green LED light (GL) and blue LED light (BL) from 1-21days and 22-42 days, respectively. The broiler birds of Group TW and TC were kept in white and incandescent LED lights for 42 days, respectively. The findings revealed that the heterophil % differed significantly (P
