More Information
Summary:When a Neanthes japonica powder having improved content of antimicrobial peptide of the present invention is added to feed and fed to fish, the activity of lysozyme in the serum of fish is increased, and the content of cortisol, a stress substance, is reduced. The feed additive of the present invention shows antimicrobial activity against streptococcus iniae, a causative organism of Streptococcal disease in fish, and Edwardsiella tarda which causes Edwardsiellosis, and thus can be usefully used as a feed additive for fish. 본 발명의 항균 펩티드의 함량이 증진된 갯지렁이 분말을 사료에 첨가하여 어류에 급이하면, 어류의 혈청 내에 라이소자임 활성을 증가시키며, 스트레스 물질인 코르티졸 함량을 감소시킨다. 또한, 어류의 연쇄구균증(Streptococcal disease) 원인균인 스트렙토코커스 이니에()와 에드워드 감염증(Edwardsiellosis)을 유발하는 에드워드시엘라 타르다()에 대한 항균 활성을 나타내므로 어류용 사료 첨가제로 유용하게 이용될 수 있다.
