Problems solved by technology

However, improper operation of artificial insemination will cause low conception rate of cattle and cause reproductive diseases
In the advanced cattle artificial insemination technology, in order to avoid contamination of the insemination gun, it is necessary to clean the rectal feces of the cow by hand, and clean and disinfect the vulva of the cow before insemination. During insemination and insemination, the cow will also excrete feces to contaminate the vulva and the tip of the insemination gun; and there are two extreme situations in this method, one is to cause excessive cleaning and disinfection, so that the disinfectant enters the vagina and is brought into the uterus during insemination , and kill sperm; the other is insufficient cleaning of the vulva, which brings feces into the vagina during operation, contaminates the vagina and causes damage to sperm

Embodiment 1

[0019] Embodiment 1 of the present invention: method of artificial insemination of cattle: (1) Determination of insemination time: the specific method for observing that the cow enters the estrus period is, on the basis of observations in the morning and afternoon in the prior art, every evening From 20 to 22 o'clock, conduct another estrus observation, and each observation time is more than 1 hour; use external observation combined with vaginal examination for estrus identification, and inseminate 6 to 10 hours after observing that the cow is standing in estrus or judging that the cow has entered estrus; (2) Thawing procedure of the frozen semen in the thin tube: Put the frozen semen in the thin tube into hot water at a temperature of 40±2°C and shake for 15 seconds, then take it out and dry the water on the surface of the thin tube with sterile gauze, and then put the thin tube Cut off the sealed end of the tube, put the thawed thin tube into the insemination gun and put it i...

Embodiment 2

[0021]Embodiment 2 of the present invention: method of artificial insemination of cattle: (1) Determination of insemination time: after observing that the cow enters the estrus period, the specific method for observing that the cow enters the estrus period is: in the prior art every morning and On the basis of observing estrus in the afternoon and morning, conduct another estrus observation every night from 20 to 22 o'clock, each observation time is more than 1 hour; use external observation combined with vaginal examination to identify estrus, and judge it as late estrus according to changes in vulva and secretions Insemination; (2) Thawing procedure of the frozen semen in the thin tube: put the frozen semen in the thin tube in a water bath with a temperature of 40±2°C and shake it gently for 15 seconds, then take it out and dry the water on the surface of the thin tube with sterile gauze. After cutting off the sealed end of the thin tube, put the thawed thin tube into the ins...

Abstract

The invention discloses a method and a device for performing artificial insemination on cows. An anti-contamination outer sleeve is inserted into the deep of a cow vagina before a semen deposition gun is inserted into the cow vagina. One hand is deeply inserted into the rectum to perform artificial insemination operation. After the hand in the rectum catches the cervix uterus, the other hand holds the semen deposition gun and enables the head of the semen deposition gun to be inserted into the cow cervix uterus to perform semen deposition through a semen deposition gun inserting hole of the anti-contamination outer sleeve, so that the step of cleaning and disinfecting the cow vulva is omitted, and contamination of the semen deposition gun is avoided. According to the method and the device for performing the artificial insemination on the cows, the artificial insemination technology is improved scientifically in an easily-grasping mode. By means of the anti-contamination outer sleeve, the cleaning and the disinfecting of the cow vulva are not needed, contamination caused in the artificial insemination process is avoided, occurrence of reproductive system diseases is reduced, the inseminated rate of cattle is improved, and the conception rate of the artificial insemination of the cows is improved.

Description

technical field [0001] The invention relates to livestock breeding technology, in particular to an artificial insemination operation method and device for cattle. Background technique [0002] At present, the application of artificial insemination technology has played an important role in the improvement and cultivation of cattle breeds in my country, and it is an indispensable key technology in cattle breeding. Under good feeding and management conditions, the conception rate during the estrus period can reach more than 50%, and the total annual conception rate can reach 85% to 90%, or even more than 95%. However, improper operation of artificial insemination will cause low conception rate of cattle and cause reproductive diseases. In the advanced cattle artificial insemination technology, in order to avoid contamination of the insemination gun, it is necessary to clean the rectal feces of the cow by hand, and clean and disinfect the vulva of the cow before insemination. ...
