Selenium-enriched feed for breeding grass carp in clear water and preparation method of feed

Abstract

The invention provides a selenium-enriched feed for breeding grass carp in clear water. The feed is prepared from, by weight, 20-30 parts of fermented bean meal, 10-20 parts fermented wheat bran, 20-40 parts of fermented soybean meal, 5-15 parts of Guimu No.1 fermented material, 5-10 parts of selenium-enriched material, 1-2 parts of sunflower seed oil, 1-2 parts of fish oil, 5-10 parts of Chinese herbal medicine additive, 1-3 parts of multi-minerals, 0.1-0.5 part of multi-vitamins, 0.1-0.3 part of 50% choline chloride, 3-6 parts of potato starch, 0.2-0.5 part of bacillus natto powder, 2-4 parts of compound enzyme preparation and 0.15-0.35 part of betaine. For the grass carp bred with the feed, the content of fibers and protein of the meat is greatly increased, the meat is tender, and the taste is delicious and cool; in addition, by adding the selenium-enriched material, absorption of selenium by the grass carp is promoted, compared with ordinary grass carp, the selenium content of the grass carp is ten times that of the ordinary grass carp, the health-care function is obviously enhanced, the immunity is enhanced, and oxidation resistance, ageing resistance and cancer resistance are achieved.

Description

technical field [0001] The invention belongs to the field of aquaculture feed, and in particular relates to a selenium-enriched feed for cultivating clear-water grass carp and a preparation method thereof. Background technique [0002] Grass carp is a common food for Chinese residents and an important source of human protein intake. With the improvement of living standards, people have put forward higher requirements for the nutrition and taste of grass carp, while ordinary grass carp will have a fishy smell when eaten, which affects the taste and reduces the quality of grass carp. The modern large-scale fish farming method has increased the production speed, but it has also brought many problems. The quality of fish products is reduced and various diseases are prone to occur, and the addition of antibiotics and additives in the feed is harmful to human health. , These problems affect the healthy development of my country's fishery. [0003] Grass carp belongs to the genus ...

Problems solved by technology

[0006] Most of the existing grass carp feeds have problems such as unbalanced nutrition, excessive addition of hormone drugs, and high content of heavy metals, which cause grass carp to be prone to various diseases and drug residues, which seriously affect the breeding efficiency of grass carp. Therefore, in order to improve the breeding efficiency , improve the quality and quality of fish products, change the feed formula, ensure balanced nutrition, improve the disease resistance and antibacterial ability of grass carp, and increase the selenium content of grass carp meat to improve its function. Modern fish farming has very good social and economic value.
