Feed for increasing growth rate of fish and preparation method of feed

Abstract

The invention discloses feed for increasing a growth rate of fish. The feed is characterized by being prepared from the following raw materials in parts by weight: 240-260 parts of sickle alfalfa, 26-28 parts of linseed meal, 16-18 parts of bran, 10-12 parts of fresh needle mushroom, 36-38 parts of coconut cake, 2-3 parts of crucian meat, 10-17 parts of shrimp shell meal, 3-5 parts of Chinese mesona herb, 0.12-0.13 part of beta-amylase, 7-8 parts of radix scrophulariae, 2.2-2.4 parts of alkaloid, 3-3.2 parts of nucleotide, 2.5-2.7 parts of DHA (dehydroacetic acid) microalgae oil, 7-9 parts of oat, 40-43 parts of honeycomb, 13-15 parts of viscous konjaku meal, and hyaluronic acid. According to the feed, a vitamin particle is prepared by filling the honeycomb with the oat, a vitamin B1 solution, phosphatidylcholine and hyaluronic acid, and a coating layer is arranged on an outer wall of the vitamin particle, so that the activity of the nutrient particle is effectively protected; a digestion function of a fish body is effectively improved; absorption of a nutrient substance is facilitated.

Description

technical field [0001] The invention belongs to the field of fermented feed for fish breeding, and in particular relates to a feed for improving the growth rate of fish and a preparation method thereof. Background technique [0002] Fish breeding, rearing and stocking. Fish farming, also known as aquaculture, fish farming and pisciculture, is important in maintaining food supplies, fishing and expanding fishing areas. Many species have been successfully introduced into new areas through fish farming. There is a type of fish farming that involves keeping goldfish and tropical fish both as a profession and as a hobby. Others include keeping minnows as bait and keeping other fish in private waters. Large quantities of fish are farmed in many parts of the world and are mostly sold commercially. However, only a few species are successfully used for this purpose, including catfish, herring, carp and salmon. [0003] Protein is an important nutrient for the survival of fish an...

Problems solved by technology

If you take too much protein, the protein that cannot be digested and utilized will be excreted in the form of nitrogen, which not only reduces the protein utilization efficiency of the body, but also increases the pressure on water quality management, and it is also easy to cause intestinal diseases.
