畜禽对硒的需要量及超微粉亚硒酸钠的应用技术

The Requirement of Selenium of Livestock and Poultry and the Applied Technology of Ultramicro Powder Sodium Selenite

文章对超微粉亚硒酸钠的营养作用、畜禽对硒的需要量、粉碎粒度与添加量的关系进行了论述。试验结果表明,超微粉碎亚硒酸钠与普通亚硒酸钠相比,提高了动物抗氧化功能,大幅提高了动物的免疫力,对其免疫球蛋白G(IgG)、谷胱甘肽过氧化物酶活性、过氧化氢酶活性、超氧化物歧化酶活性、总抗氧化力、丙二醛等指标都有不同程度的改善作用。

The nutrition function of ultramicro powder sodium selenite, the requirement.of selenium and the relation between the particle size and the dosage of selenium were discussed in this article. The results showed that compared with sodium selenite, the ultramicro powder sodium selenite had improved the antioxidant function and immunity of animals. Moreover, immunoglobulin G （IgG）, the activity of glutathiond peloxidase, catalase and Superoxide dismutase had increased, respectively. Finally,：total antioxidant capacity had increased and the amount of MDA had decreased.
