Embodiment 1

[0016] A selenium-enriched Yellow River red carp breeding method, using the Yellow River red carp as a kind of fish, using sodium selenite to make feed with a selenium content of 10mg / g, according to the body weight of the Yellow River red carp, the daily feeding amount is 1mg / g kg body weight (kg.b.w), divided into 2 doses, for the natural intake of the Yellow River red carp. Kill it on the 20th day.

Embodiment 2

[0018] A selenium-enriched Yellow River red carp breeding method, using the Yellow River red carp as a species of fish, using selenium-enriched yeast to prepare a feed with a selenium content of 20mg / g, based on the body weight of the Yellow River red carp, the daily feeding amount is 1mg / kg Body weight (kg.b.w), divided into 2 doses, for the natural intake of the Yellow River red carp. Kill it on the 11th day.

Embodiment 3

[0020] According to observation records, the daily feed intake of 0.5kg Yellow River red carp is about 15g. Take 3.2g of selenized polysaccharides with a selenium content of 2mg / kg and mix them in 10kg of feed for the Yellow River red carp to ingest naturally. At this time, the selenium content in the feed is 640mg / kg, and the daily selenium intake (calculated as selenium) of the Yellow River red carp is about 32mg / kg.b.w. After feeding for 30 days, they are slaughtered to obtain selenium-enriched Yellow River red carp with a selenium content of 100-120ug / 100g.

[0021] The selenium content of the yellow river red carp obtained by the method of the invention is obviously increased, and the content of organic selenium in the obtained product accounts for 90% of the total selenium content, so that the toxic and side effects are reduced.

[0022] After the Yellow River red carp is slaughtered, fresh meat with high selenium content can be obtained. This kind of fresh meat can be ...

Abstract

The invention discloses a farming method of the selenium-enriched Yellow River carp and relates to the field of rearing technology. The Yellow River carp is used as parent fish. Except the period of normal feeding, the Yellow River carp is drugged continuously in 10-100 days before slaughter. The drug applied is selenium-containing preparation and is applied for once or many times each day, 0.4mg / kg.b.w-30mg / kg.b.w each day by selenium. Drug application is performed by mixing the selenium-containing preparation into feed to allow the fish to eat naturally. The farming method has the advantages that a large dose of the selenium preparation is applied to the Yellow River carp before slaughter, and accordingly the fishes of the Yellow River carp high in selenium content can be obtained; products of the Yellow River carp can meet the daily requirements of people for selenium; and the farming method of the Yellow River carp is further applicable to crucian carp, silver carp, catfish, grass carp and other freshwater fishes.

Description

technical field [0001] The invention relates to the technical field of breeding rare poultry, further relates to a breeding method of selenium-enriched fish, in particular to a breeding method of selenium-enriched Yellow River red carp. 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 h...
