发酵中药渣对妊娠母猪繁殖性能、血浆生化参数和抗氧化指标的影响
Effects of Fermented Chinese Herb Residues on Reproductive Performance, Plasma Biochemical Parameters and Antioxidant Indices of Pregnant Sows
摘要
Abstract
This experiment was conducted to investigate the effects of fermented Chinese herb residues (CHR) on reproductive performance of pregnant sows, and to explore its mechanism by measuring plasma biochemical parameters and antioxidant indices.A total of 75 Landrace×Large White pregnant sows with 3 to 5 parities, similar body condition and expected date of delivery were randomly allocated to 3 groups with 25 sows per group.The animals in the control group were fed a basal diet, while those in CHR group were fed the basal diet supplemented with 1.5 kg/t CHR, and those in fermented CHR group were fed the basal diet supplemented with 1.5 kg/t fermented CHR.The experiment was throughout the gestational period.The sow numbers of estrus returning, empty, and abortion were recorded, as well as the litter size, alive litter size, and birth litter weight and birth individual weight of piglets.Eight sows per group were randomly selected on days 45, 75 and 114 of pregnancy (day of delivery).The blood was sampled via the ear vein and recovered the plasma for analysis of biochemical parameters and antioxidant indices.The results showed that dietary supplemented with CHR or fermented CHR did not significant affect the reproductive performance of sows (P>0.05).Compared with the control group, the content of plasma total protein in the fermented CHR group was significantly increased on day 114 of pregnancy (P<0.05), and the contents of plasma high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C) in the CHR and fermented CHR groups were significantly increased on day 114 of pregnancy (P<0.05);on day 45 of pregnancy, the activity of plasma catalase (CAT) in the CHR and fermented CHR groups was significantly increased (P<0.05), while the activity of plasma alkaline phosphatase (ALP) in the CHR and fermented CHR groups was significantly decreased (P<0.05).In conclusion, dietary supplemented with 1.5 kg/t fermented CHR does not affect the reproductive performance of pregnant sows, but can improve the body metabolism and antioxidant function to a certain extent.关键词
