Micro-ecological compound premixed feed containing Enterococcus faecalis and application of micro-ecological compound premixed feed in aquaculture

The invention relates to the technical fields of screening and application of functional microorganisms, and specifically provides a micro-ecological compound premixed feed containing Enterococcus faecalis CD03 and application of the micro-ecological compound premixed feed in aquaculture. The Enterococcus faecalis CD03 is screened from intestinal tracts of ''disease-resistant'' Penaeus vanname surviving in a water body with deteriorated water quality, has a preservation number of CCTCC NO:M2020089, is capable of effectively inhibiting pathogenic bacteria, enhancing the immunity and disease resistance of aquatic animals, promoting growth of the aquatic animals and efficiently purifying a water body and can be widely applied to the aquaculture field. 本发明涉及功能微生物筛选与应用技术领域，具体提供了一种包含粪肠球菌CD03的微生态复合预混合饲料及其在水产养殖中的应用。所述粪肠球菌CD03筛选自水质恶化水体中幸存的"耐病"南美白对虾的肠道，保藏编号为CCTCC NO:M2020089，能够有效抑制病原菌，提高水产动物的免疫力和抗病力，促进水产动物生长，还能高效净化水体，可广泛应用于水产养殖领域。
