Description
Technical field
The present invention relates to the livestock reproduction technology, artificial insemination operational approach and the device of especially a kind of cattle.
Background technology
At present, the application of technology of artificial insemination has been brought into play important function to China's cattle breeds improvement and cultivation, is an indispensable key technology during cattle is cultured.Under good feeding and management condition, the cattle non-return rate can reach more than 50%, and a year over-all conception rate can reach more than 85%～90% even 95%.But the artificial insemination misoperation can cause the cows conception rate low and cause the breeding disease.The cattle technology of artificial insemination in; Polluted for fear of spermatic gun; Need draw clean cow rectum place excrement with hands, and first pudendum to cow carries out cleaning and sterilizing before semen deposition, still; Such method is when cleaning pudendum and semen deposition operation, and cow also can defecate pollute pudendum and spermatic gun head; And two kinds of extreme cases of such method existence, a kind of is to cause excessive cleaning and sterilizing, makes disinfectant solution get into vagina, brings the uterus during semen deposition into, and kills sperm; Another kind of then be that the cleaning of pudendum is not enough, bring feces into vagina during operation, pollute vagina and sperm is caused damage.
Summary of the invention
The objective of the invention is: artificial insemination method and the device of a kind of cattle are provided, and it can improve the test-tube conception rate of cattle, and simplifies test-tube operation, reduces the possibility that pollutes in the artificial insemination process, to overcome the deficiency of prior art.
The present invention is achieved in that the test-tube operational approach of cattle; Before spermatic gun is inserted the vagina of cattle; Earlier anti-pollution overcoat is inserted cow vagina deep, again a hands is goed deep into rectum and carry out the artificial insemination operation, in the rectum hold cervix uteri in hand after; Another holds spermatic gun; The spermatic gun of the rifle head of spermatic gun through anti-pollution overcoat inserts a mouthful mesopore and spermatic gun is inserted the cow cervix uteri carries out semen deposition, thereby saved when artificial insemination the cleaning and sterilizing program of cow pudendum, can prevent that spermatic gun is contaminated when semen deposition is operated.
Before carrying out semen deposition operation, to observations of oestrusing of cow, change into 3 times from 2 times, concrete grammar is: observe on the basis of oestrusing in every morning and afternoon, in late 20～22 increases observation of once oestrusing, observing time is greater than 1h at every turn; Adopt visual observation to combine examination per vagina evaluations of oestrusing, observing stands oestrus back 6h～10h or be judged as according to the variation of pudendum and secretions and carry out semen deposition when oestrusing the later stage.Cow has characteristics such as estrus duration is short, ovulation is fast, the end back ovulation of oestrusing; Accurately grasping estrus time is the key factor that improves the cow conception rate; And oestrusing of cow identifies that peasant household and scale vaccary for cowboying are difficult problems; Be easy to identify the untimely service period of missing, prolong the calving interval, reduce reproductive efficiency because of oestrusing.The present invention is through increasing number of observation and the time to estrus of cow, and is chosen in suitable time and observes, and effectively improved the comprehensive and accuracy that estrus of cow is identified, the leakage that reduces cows is joined and mismatched phenomenon, has improved awarding of cows and has joined rate.
The clear and definite thawing time of straw frozen semen; Defreezing method is: it is that 40 ± 2 ℃ hot water shakes 15～20s that straw frozen semen is put into temperature; Take out the water mark of drying tubule surface with sterile gauze then, after the sealing end of tubule being cut off, the good tubule that will the thaw spermatic gun of packing into is for use again.
Adopt straw frozen semen to carry out artificial transmission & distribution and want much less than effective sperm count that natural mating gets into gential tract of dam; Therefore require to use when freezing smart transmission & distribution; Want strict control to thaw and freeze smart temperature and time; The quality of seminal fluid all was input to intrauterine to the seminal fluid of every part after assurance was thawed, and could guarantee that female animal has higher conception rate.To finding in the investigation that semen deposition person is in the operation phenomenon lack of standardization, unscientific when freezing essence of thawing; The present invention has specified a cover to implement easily; The program that easy to operate straw frozen semen thaws has effectively been avoided having improved the test-tube conception rate of cattle because of improper 2 injuries that seminal fluid is caused of thawing.
Used anti-pollution overcoat is used the bromo geramine cleaning and disinfecting earlier, and reuse flushing with clean water 4～5 times is put into calorstat then, is antibacterial 120min under 80 ℃ the condition in temperature; After anti-pollution overcoat after maybe will cleaning is dried moisture, use power to be 30W ultraviolet radiation disinfection 20min, use plastic film packaging for use at last; After anti-pollution overcoat after maybe will cleaning is dried moisture, wrap, carry out retort sterilization again with antiseptic gauze.
