Biological preparation for relieving oxidative damage of bovine oocytes

The invention provides a biological preparation for relieving oxidative damage of bovine oocytes, and belongs to the technical field of animal breeding. Specifically, the antibacterial peptide KR-12amide is applied to the technical field of bovine oocyte maturation and oxidative damage. The invention finds that the antibacterial peptide KR-12amide can effectively reduce oxidative damage of bovine oocytes and improve the maturation ability and maturation quality of the bovine oocytes, the application range of the antibacterial peptide KR-12amide is expanded, and a polypeptide drug has the advantages of strong stability and few side effects, and is safer and more effective in bovine oocyte breeding application. 本发明提供了一种减轻牛卵母细胞氧化损伤的生物制剂，属于动物繁殖技术领域。具体地，本发明将抗菌肽KR-12amide应用到了牛卵母细胞成熟和氧化损伤的技术领域。本发明发现抗菌肽KR-12amide能够有效的降低牛卵母细胞的氧化损伤，并提高牛卵母细胞的成熟能力和成熟质量，其扩大了抗菌肽KR-12amide的应用范围，而且多肽药物具有稳定性强，副作用少的优点，在牛卵母细胞繁育应用中更加安全和有效。
