Abstract
The invention discloses an artificial insemination method by using frozen boar semen, and belongs to the field of animal breeding. The artificial insemination method comprises the steps of: unfreezing the frozen boar semen before each time of insemination, performing the first time of insemination during 8h-12h after a rutting sow has stand reflection, and performing the second or third time of insemination per 8h-12h, wherein the time of insemination in rut is not more than three times, three to fives tubes of semen are used in each time, and each tube includes 0.25mL of semen. The artificial insemination method by using frozen boar semen combines conventional pig artificial insemination technology and cattle artificial insemination technology, and originally provides a frozen semen artificial insemination method applicable to pigs; according to the artificial insemination method, an insemination part can be controlled and insemination amount can be increased, and more importantly a use ratio of a boar is greatly improved.
Description
Technical field
The present invention relates to animal reproduction thremmatology, relate in particular to a kind of method of utilizing freezing pig jism artificial fertilization.
Background technology
Technology of artificial insemination is a key technology that improves buck reproductive capacity in animal reproduction.Conventional seminal fluid in Artificial Insemination Technology of Swine is the liquid seminal fluid that room temperature is preserved, this technology is applied very general aborning, and there are special industry standard, i.e. a < < Artificial Insemination Technology of Swine rules > > (NY, T636-2002).But with the technology of artificial insemination of frozen semen, also there is no special industry standard about pig; And the seminal fluid using in cattle technology of artificial insemination is Straw Frozen Semen, and the existing very ripe and standard of this technology, existing special national standard (DB37/T306-2002).But the difference of the differences of Physiological of pig and cattle and seminal fluid form, has determined to indiscriminately imitate industry standard or the national standard of cattle and Artificial Insemination Technology of Swine, can only a pig frozen semen artificial insemination method of originality invention.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of method of utilizing pig frozen semen after industrialization to carry out artificial fertilization.
Technical scheme: in order to realize foregoing invention object, the method of utilizing freezing pig jism artificial fertilization of the present invention comprises the frozen semen that thaws before each semen deposition, after quiet vertical reflection appears in the sow that oestruses, 8h ~ 12h carries out the 1st semen deposition, carries out the 2nd time or the 3rd semen deposition afterwards at interval of 8h-12h; In the oestrus, semen deposition number of times is 2-3 time, is no more than 3 times; Each semen deposition dosage is that 3-5 props up, every dosage 0.25mL.
While thawing, storage is frozen to smart semen deposition tubule and put into 38 ℃ of-40 ℃ of warm water and thaw, after all melting, take out.
Semen deposition tubule is assembled on spermatic gun, repeats to prepare 3 ~ 5 spermatic guns that assemble.
During semen deposition, paraprofessional personnel is pressed in sow back or is pressed in sow back with the sack of constant weight; Around clean sow pudendum, root of the tail and buttocks, and dry; Deferent duct by after sterilization, is coated with lubricating fluid on front end helical form glans penis; Deferent duct 45° angle is upwards inserted in sow reproductive tract, when feeling there is resistance, be slowly rotated counterclockwise, move forward and backward simultaneously, until the helical form glans penis of sensation deferent duct front end is stuck; The spermatic gun that installs straw semen is inserted in deferent duct, and will promote forward afterwards push rod through the helical form glans penis of deferent duct front end, carry out semen deposition; Insert successively the spermatic gun after assembling, insert semen deposition in deferent duct.
Beneficial effect: the present invention is in conjunction with conventional Artificial Insemination Technology of Swine and cattle technology of artificial insemination, originality has been invented the frozen semen artificial insemination method that is applicable to pig, can control insemination site on the one hand, can accomplish to expand semen deposition dosage on the one hand, what is more important has greatly improved the utilization rate of boar.
The specific embodiment
1, the semen deposition time
After quiet vertical reflection appears in the sow that oestruses, 8h-12h carries out the 1st semen deposition, carries out the 2nd time or the 3rd semen deposition afterwards at interval of 8h-12h.
2, semen deposition number of times
In the oestrus, semen deposition number of times is 2-3 time, is no more than 3 times.
3, semen dosage
Each semen deposition dosage is that 3-5 props up, every dosage 0.25mL.
4, semen thawing
With long forceps, from storage tank (liquid nitrogen container) takes out tubule, directly put into 38 ℃ of-40 ℃ of warm water and thaw, after all melting, take out, dry water.
5, semen deposition apparatus is prepared
With Special scissors, cut off the one end of not being with tampon, there being tampon one end to be contained on spermatic gun push rod, put plastic bushing, prepare 3-5 and install the spermatic gun of straw semen and the deferent duct of respective numbers.
6, semen deposition program
1. paraprofessional personnel is pressed in sow back or is pressed in sow back with the sack of constant weight.
2. semen deposition personnel decontamination cleans both hands.Around clean sow pudendum, root of the tail and buttocks, then soak towel with warm water, dry external genital.
3. from sealing bag, take out the deferent duct of sterilizing, at its front end-helical form glans penis, coat lubricating fluid.
4. deferent duct 45° angle is upwards inserted in sow reproductive tract, when feeling there is resistance, be slowly rotated counterclockwise, move forward and backward simultaneously, until the helical form glans penis of sensation deferent duct front end is stuck.
5. the spermatic gun that installs straw semen is inserted in deferent duct, and will promote forward afterwards push rod through the helical form glans penis of deferent duct front end, carry out semen deposition.
6. after the 1st straw semen semen deposition completes, spermatic gun is extracted from deferent duct, deferent duct is motionless.
7. the spermatic gun that installs the 2nd straw semen is inserted in deferent duct, and will promote forward afterwards push rod through the helical form glans penis of deferent duct front end, carry out semen deposition.
8. by that analogy, complete the semen deposition that 3-5 props up straw semen.
9. last, extract deferent duct.
10. register sow semen deposition log.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
