Selenium-enriched feed formula for egg-producing shelduck

Abstract

The present invention relates to the technical field of feeds and particularly to a selenium-enriched feed formula for egg-producing shelduck. The selenium-enriched feed formula comprises corn, wheatmiddling, wheat bran, rice bran, soybean meal, detoxified cottonseed protein, rapeseed meal, imported fish meal, stone meal, calcium bicarbonate powder, edible salt, L-lysine, methionine, choline chloride, complex enzymes, phytase, sodium sulfate, flavoring substances, ethoxyquinoline, a microbial preparation, complex multi-vitamins, Chinese yams, radix astragali, haws, licorice, dried orange peels, red dates, Chinese wolfberry fruits, radix isatidis, malt, garlic, common andrographis herb, ferrous sulfate monohydrate, copper sulfate pentahydrate, zinc sulfate monohydrate, manganese sulfate monohydrate, calcium iodate, cobalt chloride hexahydrate, methionine selenium, zeolite powder and bentonite. Beneficial effects are as follows: the selenium-enriched feed formula increases content of organic selenium in duck eggs, produces the reinforced selenium-enriched nutrient eggs integrating health care and nutrition, and achieves an effect of supplementing selenium for human body. Compared with selenium-enriched duck meat, the selenium-enriched shelduck eggs have advantages of simple operation, convenient popularization and promotion, etc.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed formula for shelduck ducks rich in selenium. Background technique [0002] Selenium is one of the trace elements necessary for the health of animals and humans. It has the functions of anti-free radicals, anti-cancer, anti-aging, improving immunity, eliminating heavy metal poisoning, maintaining growth and reproduction, and protecting the health of animals and humans. [0003] The natural content of selenium in the earth's soil is generally only 0.1-2.0mg / kg, and the content of selenium in my country is 0.047-0.993mg / kg. It can be seen that there are varying degrees of selenium deficiency in most parts of our country, resulting in the selenium content in the dietary structure. Insufficient selenium causes the human body to be deficient in selenium, causing many diseases. [0004] At present, selenium-enriched duck products are more widely and deeply researched on selenium-enr...

AI Technical Summary

Problems solved by technology

Main formulation technology, process and deficiency: 1. Adding inorganic selenium or organic selenium raw materials in excessive amounts in the feed formulation, the effect on animals

Insufficient: It has adverse effects on the health of the animals; 2. The organic selenium raw materials are obtained by spraying the fermentation substrate with selenium-rich bacteria, and the feed formula is prepared, and the target animals are

Insufficient: It is difficult to control the quality of fermented organic selenium raw materials, which may easily cause problems such as excessive mycotoxins or unstable selenium content, which will have adverse effects on the health of animals and the quality of selenium-enriched duck products is unstable; 3. Organic and inorganic selenium-enriched ducks are irrigated by field spraying Nutrient solution, producing raw materials such as selenium-enriched corn, selenium-enriched alfalfa, selenium-enriched Chinese herbal medicine, etc., to prepare feed formula, and to act on animals

Disadvantages: the heavy metals in the land are easy to exceed the standard, the land ecology is easy to be destroyed, and the composition of selenium-rich raw materials fluctuates greatly, and the quality is difficult to control
