Problems solved by technology

However, because sodium selenite is toxic, the content must be strictly controlled, and there may be unsafe hidden dangers. Therefore, there is an urgent need for a mutton sheep breeding method that can ensure that selenium poisoning accidents do not occur and can ensure the amount of selenium supplementation.

Abstract

The invention discloses a selenium-enriched mutton sheep breeding method. The method comprises the steps that selenium-enriched forage is planted, selenium-containing farm manure is applied to a meadow, sweet napier grass and astragalus sinicus are sowed in a mixed mode, selenium-containing foliar fertilizer is sprayed, and the selenium-enriched forage is obtained; silage is prepared; a sheep house of selenium-enriched mutton sheep is provided, fodder is stacked on the upper layer of the sheep house, and the mutton sheep are bred on the lower layer of the sheep house; selenium-enriched mutton sheep fattening and sheep house management are conducted, the selenium-enriched forage is used for feeding the mutton sheep, and the lower layer of the sheep house is cleaned regularly; the selenium-enriched mutton sheep are ready for slaughter. Accordingly, by culturing the selenium-enriched forage on the meadow and then preparing selenium-enriched fodder for feeding the button sheep, direct uptake of sodium selenite is avoided, and it is guaranteed that the selenium poisoning accident does not occur; meanwhile, due to the fact that the forage converts selenium absorption into the existence form of being absorbed by the mutton sheep easily, selenium absorbed by the mutton sheep is safe and reliable, the selenium content of mutton reaches the high target, and the nutritional value of the mutton is effectively improved.

Description

technical field [0001] The invention relates to the field of mutton sheep breeding. More specifically, the present invention relates to a breeding method for selenium-enriched mutton sheep. Background technique [0002] Selenium-enriched mutton is mutton with a selenium content index of 0.2-0.5 mg / kg. The selenium content in common mutton is generally 0.006mg / kg fresh meat, according to the Chinese Academy of Agricultural Sciences Animal Husbandry Research Institute completed the national selenium resource survey 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 mutton generally uses selenium at a concentration of 0.1-0.3 mg / kg in the feed (selenium in sodium selenite is 456 g / kg), but it is required that the feed must be mixed evenly, because the chemical substances used to supplement selenium Sodium selenite is highly toxic. Therefore, it i...
