Abstract:

The present study was aimed to explore the effect of monochromatic light on antioxidant function in liver and the role of melatonin in broilers.One hundred and twenty post-hatching day (P0) male Arbor Acres (AA) broilers were divided into four groups randomly and reared under the white,red,green and blue light environments (n=30).Twenty broilers from each light group was chosen randomly for pinealectomy surgery (n=10) and sham operation (n=10) at P3,and the remaining broilers were as the control group.Antioxidant assay kits were used to detect the antioxidant level in liver of broilers in different light groups reared under same environment to P14.The results showed that the T-SOD,GSH-Px,T-AOC level in liver of broilers reared under the green light in control and sham-operation groups were higher (7.82%-46.33%,P<0.05) than other various light groups,while the content of MDA was the lowest.After pinealectomy blocked the secretion of melatonin,the activity of antioxidant enzymes were reduced (12.64%-38.50%) and MDA contents were increased in various light groups.These results showed that the monochromatic light could influence the antioxidant level of liver in broilers,and green light enhanced the antioxidant function of liver.However,pinealectomy could significantly reduce the liver antioxidant level in various light groups.These results suggested that melatonin was involved in the effect of monochromatic light on antioxidant function in liver of broilers.
