Compound protein source for promoting intestinal health of aquatic animals, feed and application

The invention relates to the technical field of aquaculture, in particular to a compound protein source for promoting intestinal health of aquatic animals, feed and application. The use dosage of the fish meal is reduced, the utilization efficiency of the grouper on feed protein is improved, the intestinal health is improved, and the healthy growth of the body is met. After the dosage of the fish meal is reduced, the intestinal development of the grouper is improved, and the content of harmful bacteria is reduced. 本发明涉及水产养殖技术领域，具体涉及一种促水产动物肠道健康的复合蛋白源、饲料和应用。本发明降低鱼粉的使用剂量，提高石斑鱼对饲料蛋白质的利用效率，改善肠道健康，满足机体健康生长。本发明在降低鱼粉用量后有助于提高石斑鱼的肠道发育和降低有害菌含量。
