【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]:The aim of this study was to study the effect of residue on reproductive performance of pregnant sows, and to explore its mechanism by measuring plasma biochemical parameters and antioxidant indexes. A total of 75 Landrace 脳 large white sows were randomly divided into 3 groups, 25 in each group. The control group was fed with basic diet. The traditional Chinese medicine residue group and the fermenting Chinese medicine residue group added 1.5 kg/t of traditional Chinese medicine residue and fermented Chinese medicine residue to the basic diet, respectively. The trial period was the whole gestational period. The number of sows, litter size, live litter size, newborn litter weight and birth weight of piglets were counted. On the 45th, 75th and 114th day of gestation, 8 sows were randomly selected in each group. The blood was collected from the ear vein, the plasma was isolated, and the biochemical parameters and antioxidant indexes were measured. The results showed that there was no significant effect on the reproductive performance of sows by adding Chinese medicine residue or fermenting residue (P0.05). Compared with the control group, at the 114th day of gestation, The contents of plasma total protein (TP) in fermentation group were significantly higher than those in traditional Chinese medicine group and fermentative residue group (P0.05), and the contents of HDL-C and LDL-C were significantly increased (P0.05) on the 45th day of pregnancy, and the contents of HDL-C and LDL-C were significantly increased in the traditional Chinese medicine residue group and fermentative dregs group (P0.05). Plasma catalase (cat) activity was significantly increased (P0.05) and plasma alkaline phosphatase (ALP) activity was significantly decreased (P0.05). To sum up, the addition of 1. 5 kg/t fermentation residue did not affect the reproductive performance of pregnant sows, but could improve metabolism and enhance antioxidant function to some extent.
