Selenium-enriched feed for laying ducks and production method of selenium-enriched duck eggs

Abstract

The invention relates to a selenium-enriched feed for laying ducks and a production method of selenium-enriched duck eggs. The feed is made from selenium-enriched medicago sativa, corn, bran, soybean meal, peanut meal, rapeseed meal, cottonseed meal, stone powder, dried carrots, table salt, dicalcium phosphate, licorice roots, pine needles, bighead atractylodes rhizomes, rhizoma corydalis, radix ophiopogonis, glossy privet fruits, haws, herba cistanches, radix polygoni multiflori, erba epimedii, cortex eucommiae, beautiful sweetgum fruits, radix rehmanniae preparata, corni fructus, Chinese yams, cortex moutan, rhizoma alismatis, poria cocos and the like. The selenium-enriched feed is fed to female ducks aged at egg-laying maturity according to the feeding quantity of conventional laying ducks and a conventional raising method, and after 12-30 days, the selenium-enriched duck eggs can be produced. According to the feed disclosed by the invention, Chinese herbal medicines which can have a synergistic reaction are in reasonable compatibility, so that the immunocompetence of the female ducks can be enhanced, the stress response is eliminated, the transformation of nutrient components of the feed is promoted, the transformation efficiency of the feed is improved, the egg laying quantity of the laying ducks is increased, and the quality of the duck eggs is improved. The selenium-enriched duck eggs have the effects of supplementing selenium and promoting health of human bodies; besides, the selenium-enriched feed is used for producing the selenium-enriched duck eggs, and the production method is safe, low in cost and simple in technology.

Description

Technical field: [0001] The invention relates to the technical field of laying duck breeding, in particular to a selenium-enriched feed for laying ducks and a production method for selenium-enriched duck eggs. Background technique: [0002] Selenium is an essential trace element for the human body. Selenium deficiency can cause various diseases in the human body. Selenium deficiency in most areas of my country requires quantitative supplementation of selenium without delay. Because the range of human body’s daily safe intake of inorganic selenium is narrow, and the human body’s tolerance to organic selenium is relatively large, converting inorganic selenium into organic selenium and then absorbing it for the human body is the best way for the human body to safely supplement selenium; Supplementing selenium in the form of dietary selenium-rich foods is simple and easy to accept.

Problems solved by technology

[0003] In the Chinese invention patent application CN85108031 "Production method of high-selenium poultry eggs and meat", 6-32 mg / kg of sodium selenite is mixed in the feed to produce high-selenium poultry eggs and meat; sodium selenite is inorganic selenium, poultry The tolerance range is low, which can easily cause poisoning of laying ducks; and a kind of organic selenium (yeast selenium) provided by Chinese invention patent application CN 101491305 B "Selenium-enriched duck eggs and production method of selenium-enriched ducks" is mixed into laying duck basic diet feed Among them, it is used to produce selenium-enriched duck eggs. Although this method is safe, yeast selenium, an organic selenium, has a complicated production process and is expensive, so it is difficult to popularize in production.
