The invention provides a low-fishmeal compound feed for largemouth bass juveniles and a preparation method thereof. The compound feed is composed of 200-300 parts of steam fish meal, 100-300 parts of yeast protein, 100-200 parts of fish bone meal, and concentrated soybean. 200 parts of protein, 80 parts of corn starch, 50 parts of Antarctic krill meal, 20 parts of refined fish oil, 3 parts of lysine, 1 part of methionine, 4 parts of choline chloride, 4 parts of multivitamins for largemouth bass, largemouth bass Use 8 servings of compound multi-minerals. According to the nutritional requirements and physiological and biochemical characteristics of largemouth bass juveniles, the method selects high-quality raw materials and adds single-cell protein, which can not only meet the problems of long-term feeding without causing abnormal liver metabolism of the fry, but also can significantly improve the growth rate and survival of the fry. This reduces the use of fishmeal, thereby reducing the cost of breeding and reducing water pollution. |
