秋冬季补光时间和强度对白羽王鸽产蛋性能、血清生理生化指标及抗氧化能力的影响
Effects of Supplementary Lighting Time and Intensity on Laying Performance, Serum Physiological and Biochemical Parameters and Antioxidant Capacity of Columba in Fall and Winter
摘要
Abstract
This experiment was conducted to investigate the effects of different supplementary lighting time and intensity on laying performance, serum physiological and biochemical parameters and antioxidant capacity of Columba in fall and winter. Two hundred and eighty eight-month-old healthy Columba ( female pigeons) were paired, a total of 140 pairs with similar body weight were randomly assigned into 5 groups with 4 replicates per group and per 7 pairs per replicate. Pigeons were exposed on supplementary lighting time and intensity with 0 h and 0 lx, 4 h and 31.2 lx, 4 h and 20.5 lx, 6 h and 31.2 lx, and 6 h and 20.5 lx, respectively. The experi-ment lasted for 125 days. The results showed as follow:1) the laying rate in groups 4 h and 20.5 lx and 6 h and 31.2 lx was significantly higher than that in group 0 h and 0 lx (P<0.05), no significant difference was found among all groups on average egg weight and average daily feed intake ( P>0.05) . 2) The serum immu-noglobulin M content in groups 6 h and 31.2 lx and 6 h and 20.5 lx was significantly lower than that in group 0 h and 0 lx ( P<0.05) . The serum aspartate transaminase activity in groups 4 h and 31.2 lx, 4 h and 20.5 lx, 6 h and 31.2 lx, and 6 h and 20.5 lx was higher than that in group 0 h and 0 lx (P>0.05). 3) No obvious differences were found among all groups on the contents of prolactin (PRL), estradiol (E2), follicle, luteini-zing hormone and progesterone in serum (P>0.05), but the serum PRL content in group 0 h and 0 lx was higher than that in other groups, and serum E2 content in group 0 h and 0 lx was lower than that in other groups. 4) Compared with group 0 h and 0 lx, the serum superoxide dismutase activity in group 6 h and 31.2 lx was significantly decreased ( P<0.05) , but the serum malondialdehyde ( MDA) content in group 6 h and 31.2 lx was significantly increased ( P<0.05);the liver MDA content in group 6 h and 31.2 lx was higher than that in groups 0 h and 0 lx, 4 h and 20.5 lx, 6 h and 20.5 lx ( P<0.05) . To sum up, the pigeons can get better laying performance when supplementary lighting time is 4 h and intensity is 20.5 lx. The antioxidant ca-pacity of pigeons is weaken when supplementary lighting time is too long ( 6 h ) and intensity is too high (31.2 lx), and supplementary intensity should be no higher than 20.5 lx.关键词
