妊娠后期母猪饲粮中添加壳寡糖对新生仔猪抗氧化能力的影响
Effects of Dietary Chito-Oligosaccharide in Late-Gestation Sows on Antioxidation Capacity of Newborn Piglets
摘要
Abstract
This experiment was conducted to study the effects of dietary chito⁃oligosaccharide ( COS) in late⁃gestation sows on antioxidation capacity of newborn piglets. Sixteen cross⁃bred ( Landrace × Large White ) sows with similar weight and parity were assigned into two groups with 8 replicates per group and 1 sow per replicate. Sows in the control group were fed the basal diet, and the others in the COS group were fed the basal diet supplemented with 30 g/t COS. The experiment lasted from gestation 85 days to litter end. The results showed as follows:1) dietary COS in late⁃gestation sows had no significant effect on reproductive performance of sows ( P>0.05) , but the born process time of sows was shorten to a certain extent. 2) Dietary COS in late⁃gestation sows significant increased blood total superoxide dismutase activity of sows ( P<0.05) , and showed a trend to decrease blood malonaldehyde content (P>0.05). 3) Dietary COS in late⁃gestation sows significant increased blood glutathione peroxidase and catalase activity of newborn piglets ( P<0.05) , and showed a trend to decrease blood malonaldehyde content (P>0.05). 4) Dietary COS in late⁃gestation sows significant in⁃creased the relative expression of catalase in ileum and glutathione peroxidase 4 in jejunum of newborn piglets ( P<0.05) . In conclusion, dietary COS in late⁃gestation sows shortens the born process time of sows, and pro⁃motes antioxidant capacity of sows and newborn piglets to a certain extent.
