Sturgeon feed and preparation method thereof

Abstract

The invention belongs to the technical field of feed, and particularly relates to sturgeon feed and a preparation method thereof. The sturgeon feed is prepared from the following materials by weight percentage: 12wt% to 25wt% of soya bean meal, 15wt% to 25wt% of flour, 25wt% to 35wt% of fish meal, 5wt% to 10wt% of meat meal, 6wt% to 10wt% of refined fish oil, 5wt% to 8wt% of shrimp meal, 0.1wt% ofvitamin complexes, 0.2wt% to 0.4wt% of composite trace elements, 0.2wt% to 0.4wt% of salt, and 0.2wt% to 0.4wt% of choline. The preparation method comprises the following steps: weighing the materials by the formula; mixing all the materials except the refined fish oil to form a mixture; micro-grinding the mixture; concocting the ground materials, puffing and granulating; oven-drying, cooling andscreening the products; and post-spraying the oil to obtain the sturgeon feed. The sturgeon feed of the invention has the advantages that the time for solution is as long as about 45 minutes; the digestibility is high; the ratio between feed and meat reaches 1.2-1.5:1 and the disease-resisting rate of sturgeon eating the feed is high.

Description

technical field

[0001] The invention belongs to the technical field of feed, in particular to a sturgeon feed and a preparation method thereof. Background technique

[0002] With the development of human society, the establishment of hydropower stations in rivers and lakes and the construction of ship locks have seriously affected the self-foraging channels of sturgeons, causing rare and special aquatic products such as sturgeons to be on the verge of extinction. Sturgeon is highly praised by gourmets for its delicious meat and rich nutrition (rich in brain gold and B vitamins), and it is the first-class delicacy in food. Internationally, the United States and Germany began to study artificial compound feeds for sturgeons in the 1950s and 1960s. Chinese researchers also started research on artificial compound feeds for special aquatic products in the 1970s and 1980s, and made great progress. , Effectively promote the development of sturgeon farming. However, no greater bre...
