Health-care feed improving compactness of grass carp scales in breeding period and a preparation method thereof

Abstract

The invention relates to a health-care feed for improving the compactness of grass carp in breeding period and preparation method thereof, and belongs to the technical field of fish feed production. The feed comprises the following raw materials: 5-25 parts of soybean meal, 8-30 parts of rapeseed meal, 3-10 parts of fermented rapeseed meal, 5-15 parts of cottonseed meal, 3-10 parts of domestic DDGS, 3-10 parts of imported DDGS, 5-15 parts of rice bran, 5-15 parts of flour, 5-12 parts of corn starch, 2-5 parts of soybean oil, 1-3 parts of potassium dihydrogen phosphate, 1-2.5 parts of bentonite, 0.05-0.3 part of lysine hydrochloride at 98.5%, 0.05-0.1 part of choline chloride, 0.3-0.8 part of vitamin premix, 0.5-1.5 parts of mineral premixes, 0.01-0.05 part of an antioxidant and 0.1-0.15 part of a mildew preventive. The products can enable the immune function of the grass carps to be the best, improve the disease resistance of the grass carps, avoid the looseness and falling of the grass carp scales when the grass carps are centrally caught in the market, at the same time does not improve the feed costs, and thus can enhance the comprehensive culture benefits of farmers.

Description

technical field [0001] The invention relates to a grass carp feed and a preparation method thereof.
