Preparation method for health-care mixed feed for poly-cultured grass carp and crucian

Abstract

The invention discloses a preparation method for a health-care mixed feed for poly-cultured grass carp and crucian. The feed comprises the following raw materials, by weight, 1.5-3.5% of imported fish meal, 1.5-3.5% of domestic fish meal, 7-9% of 46.5 cotton meal, 17-19% of 46 soybean meal, 10-12% of rapeseed meal, 3-5% of puffed soybean, 9-11% of corn germ cakes, 9-11% of domestic corn alcohol lees, 0-2% of oil residues (cakes), 1-3% of intestinal membrane protein powder, 14-16% of hard wheat, 4-6% of fine wheat bran, 4-6% of full-fat rice bran, 1-3% of soybean oil, 0.3-0.5% of stone powder, 1-3% of monocalcium phosphate, 0.0-0.2% of salt, 0.2-0.4% of 70% lysine sulphate, 0.01-0.03% of 98% methionine, 0.0-0.2% of betaine hydrochloride, 0.0-0.3% of choline chloride, 0.1-0.3% of fish multi-vitamin, 0.1-0.3% of fish multi-mineral, and 0.0-0.2% of fish microecologics. The feed can keep poly-cultured grass carp and crucian to grow fast in the middle and later periods and can raise growth performance obviously.

Description

technical field [0001] The invention relates to animal breeding feed containing raw materials derived from plants, animals or minerals, in particular to a mixed grass and crucian carp health care compound feed and a preparation method thereof. Background technique [0002] In recent years, with the continuous improvement of grass carp and crucian carp breeding technology and management level, the polyculture fish farming in Yancheng City has become more and more large-scale and intensive, and it has become one of the relatively large-scale polyculture fish breeding bases in China. This represents the improvement of the level of polyculture fish farming in my country, and has also brought huge economic benefits to farmers. [0003] However, due to the rising cost of feed, pond rent, water and electricity, labor, and seedlings, as well as the pursuit of faster growth and greater yield per mu, the stocking density is higher and the quality of feed is high-end. , which can easil...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a mixed fish health-care compound feed and a preparation method thereof, which can solve the problem that the traditional mixed fish compound feed tends to cause rapid growth in the early and middle stages of mixed fish culture in the middle and late stages of culture, and the hepatobiliary syndrome often occurs in the middle and late stages. It leads to a series of problems such as growth retardation, increased mortality, reduced anti-stress ability, reduced catch rate, and intolerance to long-distance transportation.
