(一)小肽(寡肽)小肽是由2个以上的氨基酸彼此以肽键相互连接的化合物。研究发现,这些肽类物质可促进水产动物的摄食,强化氨基酸的吸收,提高蛋白质的利用与合成;增强水产动物的免疫力,提高其成活率;促进矿物质的吸收利用,减少水产动物畸形率;提高水产动物的饲料转化率和生产性能,是一种绿色饲料添加剂。在甲鱼饲料中添加肽大素(剂量为350毫克/
(A) Small Peptides (Oligopeptides) Small peptides are compounds in which two or more amino acids are linked to each other by peptide bonds. The study found that these peptides can promote the feeding of aquatic animals, strengthen the absorption of amino acids, improve the utilization and synthesis of proteins, enhance the immunity of aquatic animals and improve their survival rate; promote the absorption and utilization of minerals and reduce the abnormal rate of aquatic animals ; Improve aquatic animal feed conversion and production performance, is a green feed additives. Peptides added to the turtle feed (dose of 350 mg /
