| 摘 要： | 本试验旨在研究发酵中药渣对妊娠母猪繁殖性能的影响,并通过测定血浆生化参数和抗氧化指标探讨其作用机制。试验选用3~5胎次、体况和预产期相近的长白×大白二元母猪75头,随机分为3组,每组25头,对照组饲喂基础饲粮,中药渣组和发酵中药渣组分别在基础饲粮中添加1.5 kg/t的中药渣和发酵中药渣。试验周期为整个妊娠期,统计返情、空怀和流产的母猪数,窝产仔数、产活仔数以及仔猪初生窝重和初生个体重。分别于母猪妊娠第45天、第75天和第114天(分娩当天),每组随机选取8头母猪,耳缘静脉采血,分离血浆,测定生化参数和抗氧化指标。结果表明:饲粮添加中药渣或发酵中药渣对母猪的繁殖性能无显著影响(P0.05)。与对照组相比,妊娠第114天时,发酵中药渣组的血浆总蛋白(TP)含量显著升高(P0.05),中药渣组和发酵中药渣组的血浆高密度脂蛋白-胆固醇(HDL-C)和低密度脂蛋白-胆固醇(LDL-C)含量显著升高(P0.05);妊娠第45天时,中药渣组和发酵中药渣组的血浆过氧化氢酶(CAT)活性显著升高(P0.05),同时血浆碱性磷酸酶(ALP)活性显著降低(P0.05)。综上所述,饲粮添加1.5 kg/t发酵中药渣不影响妊娠母猪的繁殖性能,但可在一定程度上改善机体代谢,增强抗氧化功能。

| 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. |
