Description
Technical field
The present invention relates to crocodile cultural technique field, is specifically a kind of cultural method of selenium-rich crocodile.
Background technology
Crocodile is the first dragon of unique survival so far.Cold-blooded oviparous animal, change for a long time are very few.Crocodile is not
Fish, is reptile, the name of crocodile, or since it plays in the water as fish, so gain the name " crocodile ".Crocodile is so far
It was found that one of animal of earliest and most original to live.The Triassic period of coming across to cretaceous Mesozoic Era（Before about 200,000,000 years）Disposition
Violent vertebra class reptile, it and dinosaur are coeval animals, belong to flesh-eater, it is recognized that the kind of crocodile totally 23
Kind.Crocodile is the ecological value, scientific value and the high wild animal of economic value.
Modern medicine study proves that crocodile whole body is all precious, and crocodile meat, bone, first and internal organ contain abundant excellent albumen
Matter and amino acid needed by human, unrighted acid, vitamin and various trace elements.Crocodile meat is not only delicious, Er Qieneng
Fill blood, strengthen the bone, control asthma, to chronic cough, diabete（Diabetes）Also there is significant curative effect.Crocodile courage has clearing heat and detoxicating
Multiple efficacies, osteocarcinoma, hepatitis, liver cancer, carcinoma of urinary bladder, central retinitis etc. can be controlled.Crocodile liver can enriching yin nourishing the liver, improving eyesight,
Treat cataract of old people, hypopsia etc..The crocodile heart coordinates pseudo-ginseng, Radix Salviae Miltiorrhizae, mental-tranquilization, promoting blood circulation and removing blood stasis, and treats heart strand
Bitterly, myocardial anoxia, coronary heart disease etc..Cancer-resisting substance of the crocodile first containing strength, and hepatosplenomegaly, hepatic sclerosis and forefront adenoncus can be treated
It is big etc..
And selenium has 3 heavy biological functions of nutrition, toxicity and removing toxic substances concurrently, it is referred to as the protective agent of life.Selenium deficiency can trigger people
Body produces muscular dystrophy, hepatonecrosis, muscular degeneration of heart, pancreas fibroatrophy, oedema anaemia, haemolysis and reproductive capability decline
And more than 40 kinds of disease such as Keshan disease, Kaschin-Beck disease.Researcher also found a variety of diseases such as cardiovascular disease, cancer in recent years
It is related with selenium.Newest research has shown that selenium can also improve the immunity function of animal body；(such as methylate the metabolite of selenium production
Thing) there is antitumaous effect, it can inhibit the generation of cancer.Therefore, the cultivation of selenium-rich animals and plants becomes the hot spot of people's research.If can
The health-care effect of crocodile is combined with the health-care effect of selenium, prospect will be had a vast market, but in the prior art still
The undisclosed cultural method on selenium-rich crocodile.
