Problems solved by technology

However, because selenium has certain toxicity to various organisms, it is inevitable that toxic effects will occur during the long-term strengthening process, so the strengthening dose of the element cannot be too high, so that the selenium content in the product is relatively low, so it is limited in practical application

Embodiment 1

[0021] Use sodium selenite to make an aqueous solution with a selenium content of 10mg / ml, and perfuse this solution 1ml / kg body weight (kg.b.w.) orally according to the weight of the sheep, then the contact dose of the sheep (calculated as selenium) is 10mg / kg .b.w. The administration was divided into two times, and slaughtered on the second day to obtain mutton with a selenium content of 150 μg / 100 g.

Embodiment 2

[0023] Be made into the aqueous solution that selenium content is 3mg / ml with sodium selenite, according to the disposable perfusion of this solution 1ml / kg.b.w. of body weight of rabbit, then the administration dose of rabbit (calculated by selenium) is 3mg / ml. kg. b.w. Slaughter the next day to obtain rabbit meat with a selenium content of about 80 μg / 100g and rabbit liver with a selenium content of 800 μg / 100g.

Embodiment 3

[0025] Know that the daily feed intake of 2kg broiler chickens is about 100g through observation records. Take 320g of selenium-enriched yeast with a selenium content of 2000mg / kg and mix it in 1kg of feed for natural intake by broilers. At this time, the selenium content in the feed is 640mg / kg, and the daily selenium intake (calculated as selenium) of broilers is about 32mg / kg.b.w.. Slaughter on the 2nd day, obtain the chicken liver that the selenium content is 120 μ g / 100 g and the selenium content is 890 μ g / 100 g.

Abstract

The invention discloses a method of raising livestock and poultry with rich selenium: 1-5 days before butchered, the livestock and poultry is fed with medicine continuously once or a plurality of times per day by a daily feeding dosage of 0.4mg / kg.b.w.-40mg / kg.b.w.; the medicine that the livestock or poultry is fed with is a preparation with selenium; the preparation with selenium is selenite, selenate, selenomethionine, selenium-enriched yeast, selenizing polysaccharides, selenium-enriched mushroom powder or selenium-enriched albumen powder. The medicine feeding method is that the preparation with selenium is mixed with foodstuff and / or drinking water and is taken by the livestock and poultry. The livestock and poultry raised by the method have selenium content of 20Mug / 100g to 150Mug / 100g in meat and of 300Mug / 100g to 900Mug / 100g in internal organs.

Description

technical field [0001] The invention relates to the field of raising livestock and poultry, in particular to a method for raising selenium-enriched livestock and poultry. Background technique [0002] Minerals are important elements of human nutrition, among which trace elements necessary for human body play an indispensable role. However, due to factors such as geography and eating habits, the intake of essential trace elements in some populations is still insufficient. For example, selenium is one of the essential trace elements for the human body. It plays an important role in anti-free radicals, delaying aging, removing heavy metal poisoning, suppressing and fighting cancer, improving immunity, maintaining normal reproductive function, and ensuring the normal growth and development of children. effect. The daily selenium intake recommended by the Nutrition Society of my country is 50 μg for adults and 20 μg (1-3 years old) to 40 (4-6 years old) μg for children. The Am...
