水产新型饲料添加剂的研发与应用

水产饲料添加剂具有提高水产动物摄食率和饲料转化效率、促进生长和发育、调节机体代谢机能或免疫功能、增强抗病力、改善水产品品质等作用。近年来，国内外已有较多关于水产饲料添加剂的研究报道，在传统配合饲料中使用水产饲料添加剂可调控水产动物生长、品质、免疫和抗病抗应激能力，能产生良好的经济效益、社会效益和环境效益，因此水产饲料添加剂已成为科研热点和商业焦点。综述了免疫刺激剂、促生长和抗氧化剂、诱食剂、植物提取物等新型水产饲料添加剂在水产动物中的作用机制、应用效果和适宜添加剂量，并指出其存在的问题和未来的研究方向，以期为促进我国水产饲料添加剂的研究与应用提供参考。

Development and Application of New Aquatic Feed Additives

Aquatic feed additives play important roles in raising the feeding rate of aquatic animal and the feed conversion efficiency, promoting growth and development, regulating body metabolic function or immune function, strengthening disease resistance and improving quality of aquatic products. In recent years, many studies about aquatic feed additives at home and abroad have been reported. In order to produce good economic, social and environmental benefits, aquatic feed additives are used in traditional compound feeds to improve the growth and quality and regulate immunity and disease-resistant response ability of aquatic animals. Therefore, aquatic feed additives have been a hot spot of scientific researches and a focal point of business. The mechanism, application effect and appropriate dose of aquatic additives in aquatic animals, such as immunologic stimulants, growth promoters, antioxidants, feeding attractants and plant extracts were summarized. The existing problems in the previous researches and future research directions of aquatic feed additives were pointed out to provide references for the promotion of the research and application of aquatic feed additives in China.
