Fish feed and preparation method thereof

Abstract

The invention discloses a fish feed and a preparation method thereof. The fish feed is prepared from the following components in parts by weight: 15 to 20 parts of soybean meal, 15 to 20 parts of soybean concentrated protein, 5 to 15 parts of wine distiller, 10 to 12 parts of blood meal, 10 to 14 parts of corn protein powder, 5 to 10 parts of wheat, 5 to 10 parts of rapeseed cake, 1 to 5 parts ofmeat and bone meal, 1 to 4 parts of choline chloride, 1 to 2 parts of food attractant, 1 to 2 parts of yeast nucleotide, 1 to 2 parts of kiwi fruit, 0.5 to 1 part of soybean oil, 0.5 to 1 part of sesame oil, 1 to 1.5 parts of taurine, 0.5 to 1.5 parts of cholesterol, and 0.5 to 1 part of compound microbial preparation. The fish feed has the advantages that the fish meal is completely not used, sothat the feed cost is reduced, and the required nutrients are supplied for the growth and development of the fish; the feed efficiency is effectively improved, and the higher economic benefit is obtained.

Description

technical field [0001] The present invention relates to aquatic animal feed and its preparation method, in particular to a kind of fish feed and its preparation method. Background technique [0002] In the cost of aquatic animal breeding, feed cost accounts for about 50%, and the price of feed often depends on the price of protein raw materials in the feed, especially for carnivorous fish, the protein content accounts for 40-50% of the dry matter, resulting in The protein raw material is particularly dependent on the animal protein source - fishmeal. [0003] Fishmeal is the most widely used protein source in aquaculture animal feed. It not only has high protein content, but also contains essential amino acids in balance, and is rich in essential fatty acids, minerals, vitamins and other nutritional components necessary for the production and breeding of aquatic animals. [0004] Due to the overfishing of fish, the resources of wild fishmeal can no longer meet the growing d...

AI Technical Summary

Problems solved by technology

[0005] Industrial soybean protein is usually processed from defatted soybean meal. Using soybean meal instead of fishmeal protein feed will affect the palatability of the feed, reduce the feeding rate of fish, and the imbalance of essential amino acids contained in plants will cause the feed conversion rate to decrease. and reduced fish growth rates
