Antimicrobial fish feed for increasing fish yield and preparation method thereof

Abstract

The invention discloses antimicrobial fish feed for increasing fish yield. The fish feed is characterized by being prepared from the following ingredients in parts by weight: 30-32 parts of soybean meal, 20-25 parts of bone meal, 14-17 parts of spinach powder, 3-4 parts of pork extract powder, 7-10 parts of sword beans, 30-32 parts of pig tails, 80-90 parts of bread crumbs, 10-12 parts of daylilies, 0.1-0.12 part of xylanase, 9-10 parts of radix codonopsis pilosula, 0.3-0.5 part of sodium alginate, 1.1-1.3 parts of fructo-oligosaccharide, 0.6-0.8 part of calcium L-ascorbate dihydrate, 8-10 parts of salted egg yolk, 40-43 parts of honeycombs, 13-15 parts of sticky konjac flour and hyaluronic acid. The invention discloses a preparation method of the fish feed. Through the method, vitamin granules are prepared by filling the honeycombs with the salted egg yolk, vitamin B1 solutions, phosphatidylcholine and the hyaluronic acid. An outer wall of each of the vitamin granules is coated with a coating layer which can effectively protect the activity of nutritious granules and improve the digestion function of fish bodies so as to promote nutrient absorption.

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 is antibacterial and improves fish production 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.
