Compound feed for improving bodily form of grass carps and preparation method thereof

Abstract

The invention relates to a compound feed for improving the bodily form of grass carps and a preparation method thereof, which belong to the technical field of freshwater fish feeds. The feed comprises the following raw materials in parts by weight: 2-4 parts of fish meal, 10-15 parts of soybean meal, 20-30 parts of rapeseed meal, 8-12 parts of cottonseed meal, 20-30 parts of fine bran, 10-15 parts of wheat, 5-10 parts of rice bran, 0.5-1.5 parts of soybean oil, 0.01-0.05 part of a feed emulsifier, 0.05-0.15 part of choline chloride, 1.8-2.0 parts of calcium dihydrogen phosphate, 0.3 part of a vitamin premix, and 2 parts of a trace element premix. According to the invention, a feed for improving the bodily form of grass carps is developed by using a characteristic that the feeding habits of grass carps are wide, which can reduce the cost of breeding feeds, improves the bodily form of grass carps, and increases the breeding income.

Description

technical field [0001] The invention relates to a compound feed for grass carp and a preparation method thereof. More specifically, the invention relates to a compound feed for improving the body shape of grass carp and a preparation method thereof, belonging to the technical field of freshwater fish feed. Background technique [0002] Grass carp has the advantages of fast growth and high output. It is widely cultivated in various regions of China. It is the main species of freshwater ponds, lakes and reservoirs in my country. In 2011, the national grass carp production reached about 4.5 million tons. [0003] However, in the process of grass carp farming in recent years, it is easy to have fat and short fish, a high proportion of visceral weight, and a small proportion of edible parts, which is commonly known by farmers as "grass carp with big belly". With the requirements of consumers' consumption habits, the size of grass carp has become more and more important, which wil...

Problems solved by technology

[0012] The purpose of the present invention is to solve the problem of unreasonable combination of grass carp feed raw materials in the prior art, unstable quality, low cost performance, non-environmental protection, and unsustainable development, and provides a compound feed for improving the body shape of grass carp. Matching can improve the utilization rate of grass carp fat nutrition, reduce the formula cost, improve the body shape of grass carp, and the feed formula is environmentally friendly, meeting the requirements of sustainable development
