Abstract

The invention discloses a micropterus salmoides low-fish-meal-content compound feed capable of improving the intestinal health The micropterus salmoides low-fish-meal-content compound feed is formed by the following components in percentage by weight: 12-15% of fish meal, 5-12% of soybean protein concentrate, 10-20% of fermented soybean meal, 8-10% of enzymolysis soybean meal, 5-10% of chicken meal, 5-7% of corn protein powder, 5-8% of meat and bone meal, 8-12.38% of high gluten flour, 1-5% of fish oil, 3-7% of soybean oil, 0.2-1.0% of soybean lecithin, 0.2-1.0% of choline chloride, 0.5-1.0% of vitamin premix, 0.5-1.0% of mineral premix, 0.5 to 1.0 percent of calcium dihydrogen phosphate, 0.1 to 0.5 percent of L-lysine, 0.1 to 0.5 percent of L-methionine, 0.2 to 0.5 percent of taurine, 0.25 to 1.0 percent of tributyrin and 0.02 to 0.5 percent of alpha-ketoglutarate. The invention further provides a preparation method of the micropterus salmoides low-fish-meal-content compound feed. According to the invention, 70% of fish meal in an existing micropterus salmoides feed formula can be effectively replaced; the feed cost is remarkably reduced; and the growth performance of micropterus salmoides is fully guaranteed due to the fact that the intestinal health degree and the immune barrier function of micropterus salmoides are improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a largemouth bass low-fishmeal compound feed for improving intestinal health and a preparation method thereof. Background technique [0002] Largemouth bass (Micropterus salmoides) has the characteristics of fresh and tender meat, rapid growth, short breeding period, and can be domesticated and eaten with compound feed. In recent years, the annual output of largemouth bass has reached more than 400,000 tons, and it has become one of the main freshwater economic fish species in southern my country. As a carnivorous fish, largemouth bass has a very high demand for dietary protein. Among them, fishmeal, a high-quality protein source with good palatability and digestibility, can be added as high as 40%-50% in largemouth bass commercial feed. However, the supply of fishmeal resources is in short supply, and the price is rising steadily, resulting in generally high pricing of com...
