Low fish meal mixed feed for pelteobagrus fulvidraco

Abstract

The invention discloses a low fish meal mixed feed for pelteobagrus fulvidraco. The mixed feed is prepared from the following raw materials by weight percent: 15-20 percent of soybean meal, 8-10 percent of corn protein powder,10-16 percent of soybean protein peptide,15-20 percent of fish meal, 25-28 percent of wheat flour, 6-8 percent of rapeseed meal, 2-2.5 percent of calcium biphosphate, 2-3 percent of zeolite powder,4-5 percent of soybean oil, 0.5-2 percent of fish oil, 0.5 percent of vitamin premixing materials and 0.5 percent of mineral premixing materials. The mixed feed is prepared from the following steps: weighing the components according to the weight proportions; adding the materials in a mixing machine to mix fully; puffing and pelletizing; packaging to obtain a finished product. According to the mixed feed, the dependence of the pelteobagrus fulvidraco on the fish meal is reduced; the palatability of the mixed feed and the growing effect of the pelteobagrus fulvidraco are not affected; the performance-price ratio is high; the problems of limited fish meal resources, high price and low performance-price ratio are solved; the mixed feed had a wide market application prospect.

Description

technical field [0001] The invention relates to a compound feed for yellow catfish, in particular to a compound feed for yellow catfish with low fishmeal, and belongs to the technical field of compound feed for aquatic products. Background technique [0002] Yellow catfish is an important economic fish in the freshwater aquaculture industry in my country. Yellow catfish is an omnivorous fish mainly carnivorous. Because of its tender meat, rich nutrition, high yield and high economic benefits, it has become a breed that has attracted much attention in the aquaculture industry. In recent years, the culture area has shown a rapid growth trend. . [0003] At present, the special extruded feed is generally used in the cultivation of yellow catfish, and the formula is mainly based on fish meal, which is an animal-derived protein raw material. However, as a high-quality feed protein raw material, fishmeal mainly relies on foreign imports. In recent years, fishmeal production are...
