| 摘 要： | 研究了复合蛋氨酸螯合铜、蛋氨酸螫合铁、蛋氨酸螫合锰、蛋氨酸螫合锌和蛋氨酸硒对母猪血清微量元素、相关酶、激素的含量以及繁殖性能的影响，结果表明：使用复合微量元素母猪血清铜、铁、锌的水平有提高的趋势，血清锰、硒的水平则降低；配后期(配种后30d)对比于配前期(断奶后3d)，血清超氧化物歧化酶(SOD)活性有显著提高，亚铁氧化酶和谷胱甘肽过氧化物酶(GSH-PX)活性则显著降低；复合微量元素显著提高了配后期血清中亚铁氧化酶和配前期血清GSH-PX活性，降低了配后期GSH-PX的活性；有机微量元素对血清碱性磷酸酶(AKP)活性没有影响，有机微量元素对配前母猪血清中促黄体素(LH)水平没有影响，显著提高了母猪配后30d时血清中孕酮(P)水平；使用复合有机微量元素母猪的窝产活仔数提高了0．6头，平均窝质量提高了0．78k。

| Abstract: | The experiment was conducted to determine the effect of compound methionine-chelated minerals on the reproductive performance and the level of relevant minerals and enzymes in serum of multiparous sows. The period of experiment was one productive cycle. The serum of sow was collected before mating (3 d after weaning) and after conception (30 d after mating). The concentrations of Cu, Fe, Zn increased on both time points, while the concentrations of Mn and Se in serum decreased. Enzymes relevant to these minerals in serum collected before mating were significantly different from those collected after conception. In the serum collected after conception, methionine-chelated minerals reduced the activity of glutathione peroxidase (GSH-PX), increased the activity of ceruloplasmin but had no significant effect on the activity of superoxide dismutase (SOD) and alkaline phosphatase (AKP). In the serum collected before mating, methionine-chelated minerals increased the activity of GSH-PX and had no significant effect on the activity of other enzymes. Methionine-chelated minerals had no significant effect on the level of luteinizing hormone in the serum collected before mating, but significantly increased the level of progesterone in serum collected after conception. The organic minerals improved the litter size (0.6) and litter mass(0.78 kg) of multiparous sow. |
