Feed for grass carps

Abstract

The present invention relates to the technical field of feeds and particularly discloses a feed for grass carps. The feed is prepared from the following raw materials in parts by weight: 20-30 parts of grass carp powder, 10-20 parts of soybean meal, 10-20 parts of green vegetable leaves, 5-10 parts of pumpkins, 1-2 parts of edible salt, 0.5-2 parts of multivitamins, 0.5-1 part of sodium percarbonate, 0.5-1 part of methyl hydroxypropyl cellulose, 10-20 parts of sweet potato residues, 10-20 parts of algae, 10-20 parts of earthworm meal, 2-4 parts of yeasts and 0.5-1 part of trace element. The feed overcomes deficiencies of the prior art, has advantages of relatively good mouthfeel, relatively low price, rich nutrients, etc., can meet the growth needs of the grass carps, at the same time usesthe combined formula of the sodium percarbonate and methyl hydroxypropyl cellulose, slowly releases oxygen under water to form an oxygen-rich zone, uses the oxygen-rich environment to promote grass carp feeding, can effectively promote the growth and development of the young fish, enhances immunity, and is free of antibiotics and highly safe.
