Modulatory Effect of Monochromatic Blue Light on Heat Stress Response in Commercial Broilers

Figure 1

Blue light significantly increases antioxidant enzyme activities and lowers MDA concentration in the liver of two broiler strains (Ross 308 and Cobb 500). Chickens were reared in white light for 3 weeks and after that exposed to cyclic chronic heat stress with white and blue light (H + W and H + B), respectively. Liver samples were collected in sterile PBS for SOD and CAT as well as MDA measurement following the manufacture’s protocol. (a) represents SOD enzyme activity. CAT enzyme activity and MDA cellular content were shown in (b) and (c), respectively. Mean ± SEM is shown. , , and denote statistical significance (two-way ANOVA) with a , and , respectively.
