Breeding method for pig frog

Abstract

The invention discloses a breeding method for a pig frog. The method comprises the following steps of: selecting more than one pure and sexually mature male pig frog to paunch to take the testis of the pig frog out; holding in a vessel with normal saline solution; picking the involucra of the testis off by using a tool; and breaking the testis by clamping and releasing sperms to prepare sperm suspension. According to the method, since the sperms and ova of parent pig frogs of different varieties are selected, and outbreeding is performed by using an artificial fertilization method, the artificial reproduction method of hybridizing the pig frogs breaks through the conventional reproduction mode through natural spawning of the pig frogs and has great realistic significance and historical significance on promoting artificial breeding of special economic animals and particularly the pig frogs so as to improve the yield and the quality of the commercial pig frogs, enriching the vegetable basket of people, accelerating the pace of banishing poverty and becoming prosperous for rural population and even guaranteeing of sustainable and stable development of national economy.

Description

technical field [0001] The invention relates to a breeding technique for frogs, in particular to a breeding method for American frogs. Background technique [0002] The American frog is an important economic animal and has many important economic values: American frog meat is not only a rare delicacy, but also has high medicinal value; 1. The high-quality lubricating oil for precision instruments on the rocket, the head, limbs and internal organs of the American frog are high-quality feed, and the American frog is also a good insect catcher and a good helper for crops. In the past, people mainly obtained American frogs from nature. With the development of society, the increase in capture and the deterioration of the growing environment of American frogs, the number of wild American frogs has decreased. In order to meet the growing needs of human beings, for a long time, the source of American frogs mainly depends on artificial breeding. At present, artificially cultivated ...

AI Technical Summary

Problems solved by technology

At present, artificially cultivated American frog species are mainly imported from the United States. Due to the long-term breeding and mixed breeding of single or multi-species American frogs, their close relatives and blood types are similarly mated and reproduced, resulting in germplasm degradation and weak disease resistance. , The survival rate is low, generally only 30-40%; the production speed is slow, from ovulation, fertilization, hatching, tadpoles, to commercial American frogs, generally takes about one year
