Expanded compound feed capable of improving intestinal health of bighead carps and preparation method of expanded compound feed

Abstract

The invention discloses expanded compound feed capable of improving the intestinal health of bighead carps and a preparation method of the expanded compound feed, aims at providing an expanded compound feed which can improve the intestinal health of the bighead carps and the intestinal non-specific immunity of the bighead carps, maintain stability of intestinal flora and promote healthy growth of the bighead carps, and belongs to the field of aquaculture feed. According to the technical scheme, the expanded compound feed capable of improving the intestinal health of the bighead carps is prepared through the steps that a Chinese herbal medicine compound and basic ingredients are mixed, extruded, expanded and granulated, wherein the weight ratio of the basic ingredients to the Chinese herbal medicine compound is (998.0-999.7):(0.3-2), and the Chinese herbal medicine compound is prepared from, by weight, 0.1-0.5 part of fresh ginger, 0.5-1.5 parts of garlic, 0.1-0.5 part of rhizoma smilacis glabrae, 0.3-1.5 parts of folium perillae, 0.1-0.5 part of goldthread roots and 0.2-1.2 parts of plantain herb.

Problems solved by technology

[0004] In recent years, with the continuous expansion of bighead carp intensive farming and fish and shrimp polyculture models, the stocking density has continued to increase, and at the same time there are few special compound feeds for bighead carp farming in the market, resulting in improper feed selection and excessive feed feeding in bighead carp farming. And the use of inferior feed not only leads to the decline of growth performance of bighead carp, but also causes frequent outbreaks of enteritis, hepatobiliary syndrome and other nutritional diseases of bighead carp and eutrophication of aquaculture water
