Fish feed for improving raising efficiency and accelerating weight gain of fish and preparation method of fish feed

Abstract

The invention discloses a fish feed for improving raising efficiency and accelerating weight gain of fish. The fish feed is characterized by being made from the following raw materials in parts by weight: 12-15 parts of white gourd powder, 28-34 parts of rice bean powder, 19-24 parts of rice bran, 32-36 parts of onion residues, 15-17 parts of pear seed powder, 15-17 parts of corn protein powder, 34-37 parts of mung bean residues, 37-39 parts of pomacea canaliculata meat powder, 2-3 parts of pineapple protease, 8-9 parts of Japanese thistle herbs or roots, 0.6-0.8 part of dipotassium glycyrrhizinate, 0.2-0.3 part of rovimix, 0.34-0.36 part of L-carnitine, 40-43 parts of honeycombs, 13-15 parts of sticky konjaku flour, 0.8-1 part of hyaluronic acid, 0.21-0.23 part of phosphatidylcholine, 0.17-0.19 part of a vitamin B1 solution and haw crushing substances. According to the fish feed disclosed by the invention, the haw crushing substances, the vitamin B1 solution, the phosphatidylcholine and the hyaluronic acid are stuffed into honeycombs, vitamin granules are prepared, and an enveloping layer is arranged on the outer wall of each of the vitamin granules, so that the activity of nutritive granules is effectively protected, the digestive function of fish bodies is effectively improved, and the absorption of nutrient substances is facilitated.

Description

technical field [0001] The invention belongs to the field of fermented feed for fish breeding, and in particular relates to a fish feed which improves feeding efficiency and accelerates fish weight gain 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 nu...
