Embodiment Construction

[0030] The following will be further described below with reference to the specific embodiments:

[0031] See figure 1 In the present invention, a pig-based embryo propagation method includes the following steps:

[0032] Step one, donor, receptor selection, the age of the sow should be 0.8 ~ 6 years old, the weight is greater than 50 kg;

[0033] Step 2, the full physical examination of the donor and receptor and the emotional regularity is carried out;

[0034] Step three, fertilization, start with the sow, start with the same boars, use the same boar with the same boar by 12 ~ 18 hours;

[0035] Step four, embryonic collection, anesthesia to the sow, collect the embryos in the uterus;

[0036] Step 5, embryonic quality detection, record the number of embryos collected by the solid microscope, and analyze the quality of the embryo, remove the unsolved egg and the dead embryos;

[0037] Step 6, the preservation and cultivation of embryos, place the collected embryos in the incuba...

Abstract

The invention relates to the field of embryo breeding of live pigs, and particularly discloses an embryo breeding method and device based on live pigs. According to a technical scheme in the invention, the invention comprise the following steps: step 1, selecting a donor and a receptor, wherein a sow should be 0.8-6 years old and has a body weight of greater than 50 kg; and step 2, carrying out comprehensive physical examination, estrus rule recording and estrus synchronization treatment on the donor and the receptor. According to the invention, artificial intervention can be carried out on mating of boars and sows and screening and breeding of embryos, and high-quality embryos are selected for culture, so the reproductive survival rate of live pigs and the quality of piglets are improved, breeding quality is ensured while the breeding efficiency of the live pigs is improved, genes of the live pigs are selectively optimized, breeding capability and demands are enhanced, the success rate of in-vitro embryo culture and preservation is increased, and a certain protection effect is provided for in-vitro embryo culture and preservation.

Description

Technical field [0001] The present invention relates to the field of embryonic reproduction of pigs, and therefore, in particular, a pig-based embryonic propagation method and a reproductive device are disclosed. Background technique [0002] The pig, the pig, the pig, the pig, the eating animal, the body fat, the limbs are small, the nose is long, the nose is strong, easy to breed, and the pig is born 5 - 12 months can be breed, and the pregnancy is about 4 months. [0003] Most of the existing pig's embryonic breeding is direct public pig sows directly to produce a suitable time. The embryo is directly cultivated in the parent, and the outside world cannot understand the development of embryo, and the eutermate development is more fragile, resulting During the actual breeding process, the quality and quantity of pigs from producing will not meet the standard, affect the breeding benefits, so there is a kind of embryonic breeding method based on pigs and the propagation device t...
