摘要: A total of 260 one-day-old Arbor Acres male broilers were exposed to red light (RL), green (GL), blue (BL), and white (WL), respectively, by using a light-emitting diode system for 7 wk. There 5 replicate pens each treatment 13 birds per pen. The effects monochromatic on the immune response studied. results indicated that proliferation peripheral blood T lymphocytes in GL group was significantly increased (by 80.8 54.8%) compared with those RL BL groups, at 21 d age (P 0.05). By 49 age, antibody titer higher than (62.8%, P < However, no significant difference seen among BL, GL, WL groups this age. Interestingly, showed 44.0% reduction level serum interleukin-1beta as These suggest enhance better RL, may play role alleviating stress broilers.
