Embodiment 1

[0022] A selenium-enriched black swan breeding method. In addition to normal feeding, sodium selenite is used to prepare an aqueous solution with a selenium content of 10 mg / ml. According to the weight of the black swan, the solution is artificially fed to 1 mg / kg.b.w every day. , administered in 2 times, slaughtered on the 10th, to obtain the black swan meat with selenium content of 150ug / kg.

Embodiment 2

[0024] A selenium-enriched black swan breeding method, in addition to normal breeding, use selenium-enriched yeast to prepare an aqueous solution with a selenium content of 20mg / ml, and according to the weight of the black swan, artificially gavage this solution 1mg / kg.b.w every day, The administration was divided into 2 times, and slaughtered on the 10th day to obtain black swan meat with a selenium content of 150ug / kg.

Embodiment 3

[0026] A selenium-enriched black swan breeding method, through observation and records, it is known that the daily feed intake of 2kg black swan is about 100g. Get 320g of selenized polysaccharides with a selenium content of 2000mg / kg and mix them in 1kg of feed for natural intake by black swans. The daily selenium intake (calculated as selenium) of black swan is about 30mg / kg.b.w. After being raised for 10 days, they were slaughtered to obtain black swan meat with a selenium content of 120ug / kg and black swan liver with a selenium content of 890ug / kg.

Abstract

The invention discloses a method for breeding a selenium-rich black swan and relates to the technical field of breeding. The black swan is continuously fed with a selenium-containing preparation for one or multiple times each day in 10-60 days before being slaughtered, wherein the daily feeding amount is 0.4-30 mg / kg.b.w by selenium. The method has the benefits as follows: the black swan is fed with a larger amount of the selenium-containing preparation before being slaughtered, so that the meat and the organs of the selenium-rich black swan with higher selenium content can be obtained; and the products of the selenium-rich black swan can meet the daily requirements of the people on the selenium. The method further comprises breeding of a white swan, a little swan, a turkey duck, a Landes goose, a wild goose and a domestic goose.

Description

technical field [0001] The invention relates to the technical field of breeding rare poultry, further relates to a breeding method of selenium-enriched rare birds, in particular to a breeding method of selenium-enriched black swans. Background technique [0002] Selenium is honored as "longevity element" and "king of anti-cancer" by domestic and foreign medical and nutritional circles. In the 1970s, the World Health Organization announced that selenium is an essential trace element for the human body, and selenium deficiency will seriously affect human health. my country is a big selenium-deficient country. In some areas of 22 provinces and cities in the country, about 700 million people live in the low-selenium zone. The average daily intake of selenium for adults is only 26.63ug, which is far from the basic requirement of selenium. Selenium will directly lead to the decline of human immunity. Clinical medicine has proved that more than 40 diseases that threaten human healt...
