Abstract:

This experiment was conducted to investigate the effects of lighting schedules on anti-stress ability,immune function and tibia of Yellow-feathered broilers with a completely randomized design.A total of 360 0-day-old male Lingnan Yellow-feathered broilers were randomly allocated to 4 treatments with each treatment having 6 replicates of 15 birds.The lighting schedules were continuous(23L:1D),16L:8D,12L:3D:2L:3D:2L:2D and simulated natural lighting.The experiment lasted for 63 d.The total antioxidant capacity(P=0.08),Newcastle disease antibody titer(P=0.07) and Bursa of fabricius index(P=0.06) tended to be higher in simulated natural lighting group than those in other groups on 63-day-old.Creatine kinase activity tended to be lower(P=0.09) in 3 short lighting groups than that in continuous lighting group on 42-day-old.Thymus index(P=0.06) on 21-day-old and ANAE+ on 21-day-old(P=0.09) and 42-day-old(P=0.06) in short intermit group tended to be higher than those in other groups.Lighting schedules didn’t affect other parameters(P>0.05).These results show that natural or short intermit lighting condition are benefit to anti-stress ability and immune function of Yellow-feathered broilers and benefit to the health of broilers.
