Compound crucian feed and preparation method thereof

Abstract

The invention provides a compound crucian feed and a preparation method thereof. The compound crucian feed can solve a series of problems that the traditionally bred crucian grows fast in the early and middle periods, but the subsequent growth is slow, the death rate rises, the anti-stress ability is reduced and the like because hepatobiliary syndrome frequently occurs in the middle and later periods. The compound feed comprises the following formula in percentage by weight: 5-20% of imported fish meal, 10-30% of soybean meal, 10-20% of rapeseed meal, 10-15% of cottonseed meal, 10-20% of wheat, 2-3% of fish oil, 5-15% of maize germ cake, 5-15% of DDGS(distillers dried grains with soluble), 5-10% of full-fat rice bran, 1.0-2.0% of calcium biphosphate, 0.1-0.3% of salt, 0.1-0.3% of choline chloride, 0.05-0.15% of microecologics for fish, 0.01-0.02% of plant extracts, 0.02-0.04% of bile acid, 0.05-0.1% of hepatobiliary protecting agent, 0.1-0.3% of multivitamin for fish, 0.1-0.3% of multi-mineral for fish, 0.015-0.030% of vitamin E and 0.04-0.08% of 35% vitamin C phosphate. All the raw materials are finely ground, 95% of the ground raw materials pass through a 40-mesh standard sieve,the sieved raw materials are granulated at 95 DEG C, and the degree of gelatinization reaches 95%. The compound crucian feed can meet the requirements of crucian bred in the middle and later periods for nutrition, and can effectively prevent the occurrence of hepatobiliary syndrome and achieve the health protection purpose.

Description

Technical field [0001] The present invention belongs to the field of aquaculture and feed in aquatic animal animals. Specifically, it involves a catfish health care method and its preparation methods. Background technique [0002] In recent years, with the continuous improvement and improvement of catfish breeding technology and management level, Dafeng and Catfish in Yantong and Shengyang's catfish breeding have become more and more large -scale and intensive. The highest level of catfish farming in my country has enriched the people's vegetable baskets and brought high economic benefits to many farmers. [0003] However, due to the continuous rise in breeding costs such as feed, pond rent, hydropower, artificial, and seedlings, and in order to pursue faster growth, more perurone yields show more high -end revenue density, high -end feed feed qualityIt is easy to cause catfish to grow rapidly in the middle and middle period. In the middle and late stages, the follow -up growth, ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a crucian carp compound feed and a preparation method thereof, which can solve the problem that the traditional crucian carp compound feed tends to cause rapid growth of crucian carp in the middle and late stages of breeding, and slow subsequent growth and increased mortality due to frequent occurrence of hepatobiliary syndrome in the middle and late stages. , reduced anti-stress ability, poor fur, and inability to long-distance transportation are common problems when starting to catch.
