Abstract
The present invention relates to livestock-raising fields, more particularly to a kind of artificial insemination method of excellent boar, the following steps are included: semen collection, the inspection of sperm, dilution, storage, twice semen deposition, inside upper coarse and lower fine vas deferens depth insertion Gilt Uterus, conception rate can be improved, and the male and female ratio of farrowed pig is controlled, cost is saved, is increased economic efficiency.
Description
Technical field
The present invention relates to livestock-raising field more particularly to a kind of artificial insemination methods of excellent boar.
Background technique
For the pig breeding industry in rural area based on small-sized cultivation, technology content and production efficiency are low at present, and pig benign epilepsy is built
If not perfect, breeding sow wretched insufficiency, breeding pig proportion are low, infrastructure equipment falls behind, and industrialization level is not high, this
The needs of Pig Industry production development are not adapted to a bit.Technology of artificial insemination is existing as science pig raising, realization pig production
The important means of generationization, it appears particularly important.Excellent kind of Artificial Insemination Technology of Swine is the excellent herd boar sperm of acquisition, is examined by laboratory
After the programs processing such as survey, dilution, packing, preservation, boar semen is input by special equipment and is adapted in Gilt Uterus neck, is allowed to
Be pregnant the method being impregnated.
Summary of the invention
The present invention provides a kind of artificial insemination method of excellent boar, can effectively improve registration rate, conception rate, controls institute
The male and female ratio of farrowing pig, saves cost, increases economic efficiency.
A kind of artificial insemination method of excellent boar, comprising the following steps: semen collection, the inspection of sperm, dilution, storage,
Semen deposition twice, in the semen deposition step, the method for semen deposition are as follows: there is progress first time semen deposition in 12 hours after standing reaction in sow,
It is spaced second of the semen deposition of progress in 8 ~ 12 hours, first wiping sow vulva and root of the tail is wrung out with rag adhesional wetting, is then dried with paper handkerchief,
Sow vaginal orifice is broken into two with one's hands on the other hand when semen deposition, and using upper coarse and lower fine vas deferens, one holds disposable vas deferens, and 45 degree slowly obliquely
25 centimetres or so of insertion, when having resistance, vas deferens pulls slightly backward, feels that spiral head is fixed, illustrates that vas deferens has been inserted into
Cervical orifice；Sperm bottle rocking gently, it is uniformly mixed sperm, cuts sperm bottle neck portion and be connected on vas deferens, uses hand
Sperm bottle gently is pinched, using sow uterine contraction wave automatic absorption sperm, when semen deposition will stroke sow vulva or pressing sow back, reinforce
Stimulation to sow enhances the excitability of sow, improves semen deposition effect；Inseminated time rests in 5 ~ 6 minutes, avoids semen deposition
Fastly, it causes sperm to flow backwards, after sperm is finished, not allow sow to fall at once, gently sow be caught up with to move freely it, prevent from being just input into
Sperm outflow.
Inside upper coarse and lower fine vas deferens depth insertion Gilt Uterus, conception rate is substantially increased, and control and produced
The male and female ratio of piglet makes young sow yield be up to 75%, improves the utilization rate of high-quality boar, reduces aquaculture cost, reduces
The propagation of genital diseases.This method is most simple, most economical, most effective used by current cultivation boar, production market pig
Method, and one of the measure of development scale, standardization pig raising.
The utility model has the advantages that artificial insemination method of the present invention using semen deposition twice, can effectively improve registration rate, fertilization
Rate, and the male and female ratio of farrowed pig is controlled, cost is saved, is increased economic efficiency.
Specific embodiment
Embodiment 1: a kind of artificial insemination method of excellent boar, comprising the following steps: semen collection, the inspection of sperm, dilute
It releases, store, semen deposition twice, in the semen deposition step, the method for semen deposition are as follows: sow carries out first in 12 hours after there is standing reaction
Secondary semen deposition is spaced second of the semen deposition of progress in 8 ~ 12 hours, first wrings out wiping sow vulva and root of the tail with rag adhesional wetting, then uses paper
Towel is dried, and breaks sow vaginal orifice into two with one's hands on the other hand when semen deposition, and using upper coarse and lower fine vas deferens, one holds disposable vas deferens obliquely 45
Degree is slowly inserted into 25 centimetres or so, and when having resistance, vas deferens pulls slightly backward, feels that spiral head is fixed, illustrates vas deferens
Have been inserted into cervical orifice；Sperm bottle rocking gently, it is uniformly mixed sperm, cuts sperm bottle neck portion and is connected to vas deferens
On, sperm bottle is gently pinched with hand, using sow uterine contraction wave automatic absorption sperm, when semen deposition will stroke sow vulva or pressing sow back
Portion reinforces the stimulation to sow, enhances the excitability of sow, improves semen deposition effect；Inseminated time rests in 5 ~ 6 minutes, avoids
Semen deposition is too fast, and sperm is caused to flow backwards, and after sperm is finished, not allow sow to fall at once, gently sow be caught up with to move freely it, prevent
The sperm outflow being just input into.
Claims (1)
1. a kind of artificial insemination method of excellent boar, it is characterised in that: the following steps are included: semen collection, the inspection of sperm, dilute
