Feed for selenium-enriched beef cattle and raising method of selenium-enriched beef cattle

Abstract

The invention relates to a feed for selenium-enriched beef cattle and a raising method of the selenium-enriched beef cattle. The feed is made from selenium-enriched medicago sativa, corn, barley, bran, sorghum, peanut cakes, zeolite powder, baking soda, stone powder, table salt, licorice roots, bighead atractylodes rhizomes, Chinese pulsatilla roots, lumbricus, radix codonopsis, Chinese magnoliavine fruits, radix ophiopogonis, radix astragali, haws, radix angelica sinensis, radix rehmanniae preparata, rhizoma ligustici wallichii, white peony roots, dried orange peel, poria cocos and the like. The feed is mixed with a crude feed in the weight ratio of the feed to the crude feed being 1 to 3 so as to obtain a mixture, wherein the daily feeding quantity of the feed is 1.5% of the body weight of the beef cattle, then the mixture is put for feeding the beef cattle for 42-70 days before the beef cattle become full-grown and ready for slaughter, and the selenium-enriched beef is produced. According to the feed, Chinese herbal medicines which can have a synergistic reaction are in reasonable compatibility, so that the immunocompetence of the beef cattle can be enhanced, stress response is eliminated, the transformation of nutrient components of the feed is promoted, the transformation efficiency of the feed is improved, the feed conversion rate is reduced, the daily gain of the beef cattle is increased, and the quality of the beef can also be greatly improved (the meat quality is fresh, fragrant, resistant to aftertaste, rich in nutrient components and the like). The feed disclosed by the invention is used for producing the selenium-enriched beef, and the production method is safe, low in cost and simple in technology.

Description

Technical field: [0001] The invention relates to the field of breeding technology, in particular to a selenium-enriched beef cattle feed and a feeding method thereof. Background technique: [0002] Selenium is one of the 17 essential trace elements for the human body, and it is also an essential trace element for animals. The lack of trace element selenium not only affects the growth and development of humans and animals, more importantly, it seriously affects the reproductive performance of humans and animals. It is reported that after male mice ingest low-selenium diets, their body weight, testis, and epididymis weight decrease, and the concentration of sperm , motility and the number of viable sperm decreased, while the number of deformed sperm increased, ultrastructural changes. Nearly 30 mammalian selenoproteins have been discovered so far, among which glutathione peroxidase (GSH-Px) is a selenium-containing enzyme that plays an important antioxidant role in mammals, a...

[0005] The Chinese patent "Selenium Supplementation Method for Selenium-enriched Veal" (Application No.: 201310029322.4) discloses drinking a sodium selenite VE solution for one day every half a month until it is ready for slaughter to supplement selenium to the calf; however, sodium selenite is highly toxic , the difference between the poisoning dose and the nutritional dose is small, and long-term use can easily lead to selenium poisoning in beef cattle, and eating beef raised with feed containing inorganic selenium salts will endanger people's health

[0006] The Chinese patent "Selenium-enriched feed for cattle and its feeding method" (application number: 201310310841.8) discloses that selenium-enriched corn is used as selenium-enriched raw material to prepare selenium-enriched feed. Although the method is feasible, the production method is complicated and very difficult in reality. It is difficult to produce selenium-enriched corn with a selenium content of more than 20 mg / kg, and the upper limit of the selenium (Se) content (0.5-1.0 mg / kg) of the mixed feed exceeds the national feed standard (the allowable amount of selenium in feed, GB 26418-2010), difficult to promote in production
