Low-fish-meal compound feed for micropterus salmoides and preparation method of low-fish-meal compound feed

Abstract

The invention discloses a low-fish-meal compound feed for micropterus salmoides. The low-fish-meal compound feed comprises the following components in parts by weight of 25-40 parts of fish meal, 5-15parts of plasma protein powder, 5-15 parts of chicken meat powder, 10-25 parts of fermented soybean meal, 3-10 parts of peanut cakes, 4-10 parts of corn protein powder, 6-15 parts of high gluten flour, 2-6 parts of krill powder, 1-4 parts of cuttlefish cream, 1-6 parts of fish oil, 1-5 parts of soybean oil, 1-5 parts of soybean phospholipid, 0.1-0.5 part of choline chloride, 0.1-0.8 part of calcium dihydrogen phosphate, 0.5-1.5 parts of a vitamin premix, 0.5-1.5 parts of a mineral premix, 1-5 parts of inulin, 0.05-0.3 part of methionine, 0-0.5 part of bile acid and 0-0.4 part of taurine. Thelow-fish-meal compound feed for micropterus salmoides conforms to the nutrient requirement regularity of the micropterus salmoides, and has the advantages of being good in palatability and high in digestibility, increasing the survival rate, reducing the feed coefficient, improving the immunocompetence of the micropterus salmoides, and promoting healthy and quick growth of the micropterus salmoides.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, and in particular relates to a California perch low fishmeal compound feed and a preparation method thereof. Background technique [0002] California perch, also known as largemouth bass (Micopterus salmoides), belongs to Perciformes, Sunfish family, and Perch genus taxonomically, and is a typical carnivorous freshwater fish. Because of its tender and delicious meat, it is deeply loved by consumers and fishermen, and it is very popular in the international market. It is known as "freshwater grouper". my country introduced it from the United States in 1984. At present, the country has a large breeding area, mainly distributed in Guangdong, Jiangsu, Zhejiang and Sichuan. [0003] With the continuous soaring of global energy and food resource prices in recent years, the high-density and intensive farming of California sea bass has been severely restricted. On the one hand, the current fishmeal...

AI Technical Summary

Problems solved by technology

Using a variety of protein sources to replace part of the fish meal, while reducing the starch content and appropriately increasing the fat content of the California perch low-fish meal compound feed, can replace the conventional California perch feed containing a high proportion of fish meal, and solve the high cost of California perch breeding and strong dependence on fish meal. Minimize feed cost and maximize benefits, and add inulin to improve growth and immune performance of California sea bass
