Embodiment I

[0021] The selenium-enriched diet is obtained by adding selenium-containing amino acid animal nutrient solution to the mixed concentrate in the breeding stage of fattening beef cattle, and the mass concentration of selenium reaches the range of 8mg / kg~12mg / kg. Because of the breeding technology of selenium-enriched beef and beef cattle of the present invention, as long as the method of feeding the above-mentioned mixed concentrate ration with selenium-containing amino acid animal nutrient solution is fed from 25d to 35d before slaughter, the selenium content in selenium-enriched beef can be 0.20-0.50 mg / kg index requirements.

Embodiment 2

[0023] The selenium content determination results of the mixed concentrate after adding selenium-containing amino acid animal nutrient solution:

[0024] The selenium content (calculated as it is) in the mixed concentrate without adding selenium-containing amino acid animal nutrient solution is 0.025mg / kg~0.037mg / kg, while the selenium content (calculated as it is) in the mixed concentrate with selenium-containing amino acid animal nutrient solution ) is 10.02mg / kg~10.06mg / kg.

Embodiment 3

[0026] Determination results of selenium content in beef after fattening beef cattle fed with selenium-containing amino acid animal nutrient solution mixed concentrate:

[0027] The selenium content (in fresh samples) of the beef cattle fed with the mixed concentrate feed without adding selenium-containing amino acid animal nutrient solution is 0.105 mg / kg-0.115 mg / kg, while the beef cattle fed with the mixed concentrate feed with selenium-containing amino acid animal nutrient solution The selenium content (in fresh samples) in beef cattle is 0.266mg / kg-0.285mg / kg.

Abstract

The invention discloses the breeding technology of beef cattle with selenium-rich beef. A ''Guixi cattle'' beef cattle breed is used, a selenium-rich diet is obtained by a method of adding a selenium-containing amino acid animal nutrient solution into a mixed concentrate fed at the fattening beef cattle stage, and as long as feeding of fattening beef cattle is performed according to a daily feeding method from 25-35 d before slaughter, the selenium content in beef can reach the standard requirement of 0.15-0.50 mg/kg of selenium-rich beef. After feeding the fattening beef cattle with the mixedconcentrate added with the selenium-containing amino acid animal nutrient solution, it is not only beneficial to improvement of disease resistance of fattening beef cattle growth, but also to transformation of selenium and absorption of nutrients in the fattening beef cattle, organic selenium is transformed into selenoproteins through the physiological function of the beef cattle, and the nutritional value and health care function of beef quality are further improved, so that a safe, nutritious and healthy selenium-rich nutrient beef is produced, the selenium-deficient people can supplement the necessary selenium nutrient element for the human body, and thereby the selenium-rich nutrient beef is very beneficial for human health.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a breeding technology invention of selenium-enriched beef cattle. Background technique [0002] Selenium is one of the essential trace elements for human body and other mammals, and it has important physiological functions. It can improve the immunity of the body; it can significantly prevent and inhibit the occurrence, proliferation, migration and recurrence of tumors caused by spontaneous, transplantation and chemical carcinogens in animals; supplementing selenium can prevent and treat many diseases, such as Keshan disease, heart disease, etc. Vascular diseases, liver diseases and tumors, and anti-aging play an important role, and the application of selenium to prevent tumors and other diseases is a hot spot in the ascendant. The Chinese Academy of Agricultural Sciences organized national forces to conduct surveys and measurements. About 2 / 3 of China's regions are inte...
