Preparation method for epinephelussp nutrient enhancer

Abstract

The invention discloses a preparation method for an epinephelussp nutrient enhancer. The preparation method comprises the following steps: preparing a traditional Chinese medicine preparation, preparing a liposome, extracting fish viscera oil, modifying the fish oil and compounding the enhancer. The preparation method provided by the invention has the beneficial effects that the traditional Chinese medicine preparation in the epinephelussp nutrient enhancer can enhance the disease-resistant antibacterial ability of epinephelussp, improves the immunity of the organism, and strengthens physique;the modified fish viscera oil is rich in polyunsaturated fatty acid such as DHA and EPA, is suitable for being used as an nutrient enhancer for the epinephelussp, and when the nutrient enhancer is eaten by the epinephelussp, the modified fish oil improves the fat structure in an epinephelussp body; and the epinephelussp nutrient enhancer contains rich nutritional components such as traditional Chinese medicinal components, phospholipid, unsaturated fatty acid, proteins, composite enzymes, and mineral elements, cooperates with a phagostimulant and an antioxidant component, accordingly is suitable for being used as the nutrient enhancer for the epinephelussp, and after being matched with fodder for feeding, the epinephelussp nutrient enhancer can enhance the stress capability, the immunocompetence, the disease-resistant antibacterial ability of the epinephelussp, promotes the digestion and absorption of the epinephelussp to nutrients, and accelerates the growth and development of the epinephelussp.

[0004] The Chinese invention patent of CN 101803673 B discloses a grouper compound feed and its preparation method. The invention method combines fish meal, soybean meal, wheat high-gluten flour, flour, yeast powder, compound vitamins, compound minerals, choline, Calcium dihydrogen phosphate, gelatin, VC, and shrimp skin powder are mixed to prepare feed, which has the advantages of simple preparation and comprehensive nutrition, but its main raw material, fish meal, is expensive, and large-scale application increases the cost of feed. The medicinal ingredient of grouper, unfermented soybean meal contains anti-nutrient components, which affects the absorption and digestion of feed nutrients by grouper
