Technical field
This utility model relates to animal and uses apparatus, specifically a kind of special implement that can be used for degree of depth semen deposition of pig intrauterine or non-operation embryo transfer is mainly used in embryos' such as the degree of depth input of seminal fluid such as pig dilution seminal fluid, frozen semen, property control seminal fluid and pig in-vitro fertilization, somatic cell clone, transgenic transplanting.
Background technology
The artificial insemination of pig intrauterine is with a kind of insemination technique of sperm by vagina input cornua uteri.Pig intrauterine technology of artificial insemination has the nearly all advantage of traditional technology of artificial insemination (cervix uteri place), has reduced each semen deposition semen volume and sperm concentration in addition significantly, introduces and raise expenses thereby reduce breeding boar.
All there are the huge sperm wasting of resources in pig natural mating and traditional artificial insemination mode, every part of seminal fluid needs 30～4,000,000,000 sperms, pig intrauterine technology of artificial insemination is no less than 1,000,000,000 sperms to every part of total sperm count of seminal fluid of seminal fluid requirement requirement and gets final product, in addition, the intrauterine artificial insemination can prevent seminal fluid refluence phenomenon effectively, and the genetic potential of giving full play to superfine boar has been opened up new way.Especially the use that is difficult for acquisition seminal fluid such as special seminal fluid such as frozen semen or property control seminal fluid is had great importance.
Embryo transfer is meant from the body early embryo of jenny live body collection or the embryo that obtained by external fertilization and other modes, is transplanted to the identical jenny intrauterine of other end physiological status, makes it to continue to develop into the process of new individuality.
Mammiferous embryo transfer originates in the thirties in 20th century, after the sixties, technology such as the superovulation that matches with embryo transfer, estrus synchronization, embryo freezing, the non-operation collection of embryo and transplanting are studied successfully on some animal, making embryo transfer technology begin to enter produces and commercialization, especially the non-operation embryo transfer technology of cattle, sheep has formed very perfect technical system.The method of pig embryo transfer is mainly modus operandi and transplants, the modus operandi embryo transfer needs strict surgical operation, increased difficulty and expense and receptor has been caused certain injury, and the generation of adhesion is often arranged after the operation, cause same pig not recycle, so its application in commercially producing has been subjected to certain restriction.
The non-operation embryo transfer of pig is to adopt a kind of instrument that the embryo is input to cornua uteri, do not need anesthesia, surgical operation, pig is not had injury, but this technology is owing to many-sided reason does not enter commercialization at present as yet.Because pig is a multiparous animal, embryo transfer is absorbed in the narrower mistaken ideas of range of application on the one hand; Pig genitals complex structure on the other hand, as cervix uteri Zou pleat more dark, cornua uteri is long etc., does not also set up non-efficiently operation transplantation method as cattle.
Carrying out the input of embryo transfer or seminal fluid needs an auxiliary facilities, and grafting device commonly used at present per vaginam guiding tube and uterus input pipe is socketed to form, but because the phallic complex structure of pig, the embryo of prior art or sperm transplantation utensil have following shortcoming:
1, the top end opening of pipe in the utensil is transplanted in the tolerant easy obstruction of intrauterine, causes embryo or seminal fluid to be difficult for input;
2, the joint of uterus input pipe hurts uterus and the vagina of pig easily.
The utility model content
For solving the problem that prior art exists, this utility model provides a kind of pig intrauterine insemination simple in structure, easy to use, simple to operate or non-operation embryo transfer utensil.
This utility model is achieved in that
One boar intrauterine insemination and non-operation embryo transplanter tool, this utensil comprise vagina guiding tube and uterus input pipe, and described vagina guiding tube is socketed in outside the input pipe of uterus, and described vagina guiding tube front end is provided with lubricated buffer head; Described uterus input pipe joint cross section is oval, and the joint front end is the globoidal structure that radius of curvature is changed from small to big, and the joint both sides respectively have aperture, and input pipe rear end, uterus is trumpet-shaped input port.
Optionally, described uterus input pipe is a three-decker, and internal layer is a polyethylene hose, and the intermediate layer is the rustless steel steel ring, and skin is a heat-shrink tube, and described internal layer flexible pipe is connected with joint.
Optionally, described joint adopts rustless steel to make, and the joint both sides respectively have 2 apertures.
Optionally, described lubricated buffer head employing sponge making.
The pig that this utility model provides has the following advantages with intrauterine insemination or non-operation embryo transplanter:
1, simple in structure, easy to use, simple to operate, can finish intrauterine insemination or embryo's transplanting;
2, input pipe joint cross section in uterus is oval, and the joint front end is the globoidal structure that radius of curvature is changed from small to big, and has both guaranteed that the uterus input pipe carried out smoothly, does not injure cervix uteri and endometrium again, uses safer;
3, the joint both sides respectively have aperture and can avoid blocking the transplanting that influences embryo or seminal fluid because of cervix uteri lacuna or mucus.
