Cold water fish forage

Abstract

The invention provides a cold water fish forage. The forage comprises raw materials of, by weight: import fish meal 14-16 parts, domestic fish meal 7-9 parts, yeast powder 3-5 parts, soybean phospholipids 3-5 parts, soybean meal 28-32 parts, peanut meal 16-18 parts, chicken blood meal 2-3 parts, cinnamon meal 1-2 parts, epimeddium meal 2-3 parts, spirulina meal 4-6 parts, wheat gluten meal 5-7 parts, fish oil 1-2 parts, calcium lactate 0.4-0.6 parts, calcium dihydrogen phosphate 2-3 parts and rhizoma polygonati meal 0.02-0.04 parts. The cold water fish forage is prepared with a conventional puffed fish forage preparation method by puffing granulation, drying, oil injection and cooling. The cold water fish forage is anecological environment-friendly green fish forage; when fish is fed with the cold water fish forage provided by the invention, a use ratio of the cold water fish forage is high; antiviral ability of fish is strengthened; a growth rate of fish is increased; a survival rate of cold fish is increased; and culture benefit is increased.

Description

technical field [0001] The invention relates to the field of fish feed processing, in particular to a cold-water fish feed and a preparation method thereof. Background technique [0002] Human beings call for health, eager to return to nature, and urgently need "green food", of course, including green animal products and aquatic products, and these green products also need green feed. No pollution, no residue, no drug resistance, no toxic and side effects of nutrition and health green aquatic feed is the main trend of current and future aquaculture needs. [0003] The industrialized farming of cold-water fish is still in its infancy in my country, and the farmers are mainly concentrated in the coastal areas of Shandong, my country. After several years of breeding, it was found that cold-water fish had a high mortality rate and relatively slow growth, which greatly damaged the breeding benefits of the breeder. Although the feeder also made some improvements or updates in ter...

AI Technical Summary

Problems solved by technology

After several years of breeding, it was found that cold-water fish had the problems of high mortality and relatively slow growth, which greatly damaged the breeding benefits of the breeders. Although the feeders also made some improvements or updates in fish feed, feed additives or breeding methods, However, fish survival or mortality and disease resistance did not improve significantly
