Selenium-rich beef breeding method

Abstract

The invention discloses a selenium-rich beef breeding method. The selenium-rich beef breeding method comprises the following steps: planting and processing selenium-rich forage: applying selenium-containing farmyard manure to a grassland, sowing ryegrass and Chinese trumpet creeper in a mixed manner, and spraying a selenium-containing leaf fertilizer to obtain a selenium-rich feed; providing an oxtall for selenium-rich beefs: stacking the feed on an upper-layer oxtall, and breeding the beefs on a lower-layer oxtall; fattening the selenium-rich beefs: feeding the beefs with the selenium-rich feed; and slaughtering the selenium-rich beefs. As the selenium-rich forage is planted on the grassland and then prepared into the selenium-rich feed to feed the beefs, direct ingestion of sodium selenite is avoided, and an accident of selenosis cannot occur; and meanwhile, as the forage converts selenium absorption into the existence form easily absorbed by the beefs, selenium absorbed by the beefs is safe and reliable, the selenium content of the beefs reaches high indexes, and accordingly, the nutrition value of the beefs is effectively improved.

Description

technical field [0001] The invention relates to the field of beef cattle breeding. More specifically, the present invention relates to a breeding method for selenium-enriched beef cattle. Background technique [0002] Selenium-enriched beef is beef with a selenium content index of 0.2-0.5 mg / kg. The selenium content in ordinary beef is generally 0.006mg / kg fresh meat. According to the national selenium resource survey completed by the Animal Husbandry Research Institute of the Chinese Academy of Agricultural Sciences in February 1984, the result is that 72% of the counties and districts in the country belong to selenium-deficient and severe selenium-deficient areas. At present, selenium-enriched beef generally uses selenium at a concentration of 0.1-0.3mg / kg in the feed (selenium in sodium selenite is 456g / kg), but the feed must be mixed evenly, because the chemical substances used to supplement selenium Sodium selenite is highly toxic. Therefore, it is very important to ...

AI Technical Summary

Problems solved by technology

But because sodium selenite is poisonous, the content must be strictly controlled, and there may be unsafe hidden dangers. Therefore, there is an urgent need for a beef cattle breeding method that can ensure that selenium poisoning accidents do not occur, and can ensure the amount of selenium supplementation at the same time.
