Embodiment 1

[0018] A method for supplementing selenium in selenium-enriched veal, the method comprising the steps of: preparing sodium selenite V E Solution; Weaned calves at the age of 2 to 3 months, while implementing rapid fattening with grain feed, drank the sodium selenite V for one day every half a month E solution, drink the sodium selenite V E The solution weighs 8% of the cow's body weight until slaughter.

Embodiment 2

[0020] According to the selenium-enriched veal selenium supplement method described in Example 1, the preparation of sodium selenite V E The solution is 0.1% by weight of sodium selenite V E The solution was diluted with water to a concentration of 10ppm sodium selenite V E solution.

Embodiment 3

[0022] According to the selenium-enriched veal selenium supplement method described in embodiment 1 or 2, the sodium selenite V E The ratio of vitamin E and sodium selenite in the solution is 50:1.

[0023] principle:

[0024] The bioavailability of selenium sources for cattle has been studied in traditional technology, and the relative bioavailability of selenium sources is 100% with sodium selenite. After oral selenium preparations are taken by ruminants, about the same amount of selenium is excreted through the digestive tract and urinary system, accounting for about 30%-35% of the intake of selenium, and another 2%-3% of selenium is in the form of dimethyl selenium from the respiratory tract Excretion; endogenous selenium enters the duodenum with bile secretion and is excreted with feces. Normally, only 20%-25% of the intake is retained in ruminants.

[0025] The recommended amount of selenium in beef cattle diets is 0.1-0.3mg / kg diet.

[0026] Selenium is found in al...

Abstract

Disclosed is a selenium supplementing method for selenium-rich milk veal. Selenium content of ordinary fresh beef is generally 0.006mg / kg, and according to results of selenium resource survey conducted by Institute of Animal Science, Chinese Academy of Agricultural Sciences in February, 1984, 72% of national counties are selenium-deficient and severe selenium-deficient regions. In the prior art, selenium deficiency prevention is achieved only by preventing selenium deficiency during beef cattle breeding, but specific selenium supplementing methods and selenium supplementing quantity of selenium-rich beef are not provided. The method includes: preparing sodium selenite VE (vitamin E) solution; and feeding grain feed to weaned calves of two-three months old while enabling the calves to drink the sodium selenite VE solution for one day every half a month until the calves are fattened for sale, wherein the sodium selenite VE solution drinking weight accounts for 8% of the weight of each calf. The method is used for increasing selenium content of the beef.

Description

Technical field: [0001] The invention relates to a method for supplementing selenium with selenium-enriched veal. Background technique: [0002] The concept of selenium-enriched veal, veal refers to beef before sexual maturity, selenium-enriched veal refers to [0003] It is veal with a selenium content index of 0.2-0.5mg / kg in fresh veal. [0004] The selenium content in common beef is generally 0.006mg / kg fresh meat. According to the national selenium resources 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 deficiency and severe [0005] Selenium-deficient areas. [0006] 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 seleni...
