Feed for breeding of river silver carps and preparation method of feed

Abstract

The invention discloses feed for breeding of river silver carps and a preparation method of the feed. The feed is prepared from the following raw materials in parts by mass: 55-75 parts of grains, 18-26 parts of soybean meal, 12-22 parts of corncob, 13-26 parts of straw, 10-19 parts of fungus chaff, 20-35 parts of leaves of artemisia argyi, 19-22 parts of earthworm powder, 30-45 parts of calcium superphosphate, 25-45 parts of algal powder, 25-45 parts of betaine, 13-26 parts of bran, 3-8 parts of amaranth powder, 13-26 parts of rapeseed meal, 13-15 parts of sesame oil and the balance of corn meal. The feed is prepared from the fungus chaff and waste or damaged edible fungi as raw materials, effectively uses the value of the fungus chaff and the waste edible fungi and reduces the possibility of environmental pollution, the prepared silver carp feed has rich and balanced nutrients, contains rich minerals meeting growth requirements of the silver carps and is aromatic in smell and good in palatability.

Description

technical field [0001] The invention relates to a feed for river silver carp cultivation and a preparation method thereof. Background technique [0002] Mushroom bran is the waste left after the cultivation of edible fungi, which is produced by the mycelium residue of edible fungi, cellulose, hemicellulose, lignin, and bio-enzymatic conversion process that have undergone enzymatic hydrolysis to varying degrees. A compound composed of various sugars, organic acids, enzymes, biologically active substances and minerals and other nutrients. After the substrate is fermented by a variety of microorganisms, the crude protein and crude fat are significantly increased, the crude cellulose is significantly reduced, and it is rich in amino acids, fungal polysaccharides and trace amounts of Fe, Ca, Zn, Mg, etc. element. At present, the vast majority of fungus chaff in our country is incinerated and discarded, resulting in a great waste of resources, and unreasonable treatment has brou...

AI Technical Summary

Problems solved by technology

At present, the vast majority of fungus chaff in our country is incinerated and discarded, resulting in a great waste of resources, and unreasonable treatment has brought serious ecological pollution. A large number of discarded or damaged fungi also contain a large amount of protein, fat, enzymes, amino acids, fiber and other nutrients, and their improper handling can easily lead to ecological pollution
