Se-rich meat duck feed and Se-rich meat duck breeding method

Abstract

The invention relates to Se-rich meat duck feed and a Se-rich meat duck breeding method. The feed is prepared from Se-rich alfalfa, corn, flour, rice bran, broomcorn, dried carrots, edible salt, mountain flour, common andrographis herbs, roots of Chinese pulsatilla, dangshen, fruits of Chinese magnoliavine, glossy privet fruits, pine needles, largehead atractylodes rhizomes, astragalus membranaceus, Chinese angelica, prepared rehmannia roots, rhizoma chuanxiong, white peony roots, dried tangerine peels, poria cocos, eucommia bark, common selfheal fruit-spike, sweet wormwood and the like in certain proportion; meat ducks 12-40 days before marketing are fed with the feed with a conventional meat duck feeding quantity and feeding method, and the Se-rich meat ducks are produced. The feed is reasonably combined with synergistic Chinese herbal medicines, so that immunity of the meat ducks can be enhanced, stress response is eliminated, conversion of nutrients in the feed is promoted, the conversion efficiency of the feed is improved, a feed / meat ratio is reduced, the daily gain of the meat ducks is increased, the quality of duck meat is improved, and the duck meat is delicious, has long aftertaste, is rich in nutrients and has functions of supplementing Se and promoting health of a human body; with the adoption of the feed and the method, the produced Se-rich duck meat is safe and low in cost, and the process is simple.

Description

Technical field: [0001] The invention relates to the technical field of breeding, in particular to a feed for selenium-enriched meat ducks and a breeding method thereof. Background technique: [0002] Selenium is an essential trace element for human body. Cancer, liver disease, cardiovascular and cerebrovascular diseases, diabetes, cataracts, and low immunity are closely related to the lack of selenium in the human body. my country is a major selenium-deficient country. Two-thirds of the country is selenium-deficient, of which 1 / 3 are severely selenium-deficient. Residents in selenium-deficient areas suffer from insufficient selenium content in food, vegetables, and fruits due to the lack of selenium in the local soil In the past, the level of selenium in the human blood has been reduced for a long time, which is likely to cause diseases such as cardiovascular and cerebrovascular diseases, diabetes, cataracts, low immunity, child development and reproductive capacity. Therefore,...

Problems solved by technology

However, directly adding inorganic selenium salts such as selenite to the feed can increase the selenium content in the feed, but due to the high toxicity of inorganic selenium salts, it is easy to cause selenium poisoning in poultry, and long-term consumption of feed containing inorganic selenium salts Duck meat is harmful to people's health. The Japanese government has banned the addition of inorganic selenium salts in food and feed as early as 1993; while organic selenium has a high absorption rate and low toxicity risk; but existing organic selenium such as yeast selenium added, The production process is complex and expensive, and it is difficult to promote in production
