随着生物工程的发展,国内外生物科技的动态趋向新颖生物活性物质添加剂的研究与开发,藉以增强鱼类和畜禽动物的体质与抵抗病原体的能力,并冀于防止化学药物所造成的全球性的环境污染以及人、畜、水产品中的残留威胁人类的健康。生物活性剂是从植物中选取某些具有既能穿透细胞膜、孢壳等介质,又能增强血液循环、提高特异性抗病原能力的活性物质的中草药和提炼出的寡糖、多糖、绿原酸、生物碱、多酚和黄酮等纯天然生物活性复合物,易被动物机体吸收而无药物残留和毒副作用的新一代添加剂。它能增强机体新陈代谢,有助于调节神经传导和酶系统平衡及产生特异抗体等,
With the development of bioengineering, the dynamic trends of biotechnology at home and abroad tend to be the research and development of novel bioactive substance additives to enhance the physique of fish and livestock and animals and the ability to resist pathogens, and to prevent the worldwide impact caused by chemical drugs Sexual environmental pollution and residues in human beings, livestock and aquatic products threaten human health. Bioactive agent is selected from the plant with some can penetrate the cell membrane, the shell and other media, but also enhance blood circulation, improve the specific anti-pathogenic activity of the active substance of Chinese herbal medicine and extracted oligosaccharides, polysaccharides, green Natural acids, alkaloids, polyphenols and flavonoids and other natural bioactive compounds, easily absorbed by the animal body without drug residues and toxic side effects of a new generation of additives. It can enhance the body’s metabolism, helps regulate nerve conduction and enzyme system balance and produce specific antibodies,
