Description
Technical Field
The present invention relates to the field of aquaculture. More particularly, the invention relates to a breeding method of alligators.
Background
Crocodile is a relatively original reptile, belongs to the class of reptiles, the order of crocodiles and the family of crocodiles, is rare in China at present, and belongs to the country to protect animals. Crocodile is a wild animal with high economic value. The meat is not only fresh, tender and delicious, but also has high nutritive value. Such as crocodile meat, bones, nails and internal organs, contain rich and excellent proteins and amino acids, unsaturated fatty acids, vitamins and various trace elements which are necessary for human bodies. The crocodile gallbladder has the effects of detoxifying, clearing heat, removing nebula, promoting tissue regeneration and promoting metabolism, can be used for treating bone cancer, liver cancer, bladder cancer, central retinitis and food poisoning, and particularly has obvious curative effects on fatty liver and liver cirrhosis; crocodile gall is a very valuable herb in Thailand, which is used for treating female infertility and irregular menstruation and is regarded as a Lingdan wonderful medicine. Crocodile liver has the functions of nourishing brain, promoting new blood generation, removing dampness, nourishing yin and liver and improving eyesight, and can be used for treating senile cataract, hypopsia and the like. The crocodile heart is matched with the pseudo-ginseng and the salvia miltiorrhiza to nourish heart and calm nerves, promote blood circulation and remove blood stasis, and treat angina, myocardial anoxia, coronary heart disease and the like. Crocodile bone can be used for treating and preventing rheumatalgia. The crocodile bone powder contains a large amount of active calcium, phosphorus and the like, and can be used for treating senile osteoporosis, infantile calcium deficiency and the like.
With the improvement of the living standard of people, China pays attention to diet nutrition for a long time and gives a good idea of food supplement, and the crocodile meat is meat with higher nutritional value and is popular with consumers all the time. The demand of the method has great space for increasing, and the method has wide market prospect in China.
In recent years, artificial crocodile breeding is gradually started and becomes a breeding project which is favored by most of farmers, however, most crocodile farmers still know nothing about crocodile breeding technology, in the technical link of artificial crocodile breeding, a breeding method of crocodiles is one of the keys, because good offspring can be cultured by breeding crocodiles, but the traditional breeding method is not targeted, and the problems of low egg laying rate, poor quality of the offspring of crocodiles and the like are difficult to avoid.
