Breeder alligator breeding method for improving zygotes and laying rate of Chinese alligators

Abstract

The invention discloses a breeder alligator breeding method for improving zygotes and the laying rate of Chinese alligators. The method comprises the steps of controlling of the population number, breeding pond preparation, hibernation cave preparation, diversified fodder feeding, breeder alligator enclosed environment preparation, breeding egg collecting and orientation marking. According to the method, the laying number of Chinese alligators is increased, the fertility rate is improved greatly and reaches 85%, and the incubation survival rate reaches 80% of the total egg number, so that the number of the Chinese alligators can be effectively increased in a short time, and protection of the Chinese alligators is facilitated.

Description

technical field [0001] The invention relates to the technical field of crocodile breeding, in particular to a crocodile breeding method for improving the fertilized eggs and egg laying rate of Chinese alligator. Background technique [0002] Chinese alligator is a kind of crocodile unique to China, and it is also the most endangered species among the 23 existing crocodiles in the world. It was listed as critically endangered (CB) by the UCN Red List of Threatened Species in 2000; The Chinese Alligator Reserve and the Chinese Alligator Breeding Research Center have been established. After more than 40 years of efforts, the number has grown from 200 to 10,000. It should be said that the results are remarkable; Chinese alligators are sexually mature at 5 to 6 years old, and each can lay 20 to 40 eggs per year. If calculated according to the egg-laying capacity of Chinese alligators, there should be more than 10,000 eggs in 8 years of protection, and more than one million eggs s...

Problems solved by technology

[0002] The Chinese alligator is a crocodile unique to China, and it is also the most endangered species among the 23 existing crocodiles in the world. It was listed as critically endangered (CB) by the UCN Red List of Threatened Species in 2000; China began to protect it in the 1970s. The Chinese Alligator Reserve and the Chinese Alligator Breeding Research Center have been established. After more than 40 years of hard work, the number of alligators has grown from 200 to 10,000. If calculated according to the egg-laying capacity of Chinese alligators, there should be more than 10,000 alligators in 8 years of protection, and more than one million in 40 years of breeding, but now there are only about 10,000. This fully shows that there are problems in the breeding methods of alligators in artificial breeding. Crocodile does not lay eggs, 2. Low fertilization, 3. Low hatching rate

[0003] According to the analysis of the survival characteristics of wild Chinese alligators, the living environment of artificially raised Chinese alligators is not as good as that in the wild. The bait ingredients are single, malnourished, and hibernation is not good. External interference greatly affects the breeding of alligators. They collect eggs in egg-laying nests, and the orientation marks are not accurate. The direction in which the egg is placed is different from that of artificial hatching, which affects hatching
