Problems solved by technology

This method of insemination has many disadvantages: (1) It is very irritating to the reproductive tract of the female animal. After insemination, the female animal often has a urination reaction (even if there is very little urine). According to our observation, the inseminated female donkey with this reaction reaches 80-90%, the urine test of the inseminated female donkeys found that 23.5% of the urine of the female donkeys after insemination contained sperm, which shows the seriousness of the semen reflux caused by urination
(2) Animals have a stronger stress response, which may affect the timing of ovulation and even the quality of eggs in female animals
(3) Since this method of insemination can easily cause damage to the uterus and vagina and easily bring microorganisms into the reproductive tract, this method of insemination can easily lead to infection of the reproductive tract

Embodiment 1

[0042] See attached Figure 1-3 , a special visual insemination device for equine animals, which includes an outer cylinder 1, a vas deferens 2, an endoscope 3 and an inflation device 4;

[0043] Described urceolus 1 is long 80cm, and diameter is 3.5cm, and urceolus interior has endoscope installation channel 1-1 and the working channel 1-2 for vas deferens insertion, and endoscope installation channel 1-1 caliber is 0.8cm, and working channel 1-2 caliber is 1.5cm;

[0044] The endoscope 3 is fixedly installed in the endoscope installation passage of the outer cylinder, the front end of the endoscope is flush with the front end of the outer cylinder, and the cable at the tail of the endoscope is drawn backward from the endoscope installation passage;

[0045]Described vas deferens 2 comprises outer layer flexible pipe 2-1 and hard inner core 2-2, and outer layer flexible pipe 2-1 length is 90cm, and the front end of outer layer flexible pipe is arc surface (arc surface can re...

Embodiment 2

[0048] Further, the inflatable device adopts a latex inflatable ball with a valve. The endoscope adopts the model WF100 endoscope of Teslong / Taishilang, and the endoscope can be wired or wirelessly connected with the mobile phone, and the captured image of the endoscope can be displayed by the mobile phone.

Embodiment 3

[0050] See attached Figure 4-6 On the basis of Embodiment 1, further, the visualized insemination device also includes an endoscope scraping device, which is composed of a rotating rod 5, a scraping head 5-1 and a tail handle 5-2, Wherein, the rotating rod 5 is rotatably installed in the outer cylinder (the outer cylinder is provided with a rotating rod mounting hole 1-3 for installing the rotating rod 5), the diameter of the rotating rod is 2.5 mm, and the front end of the rotating rod extends out of the outer cylinder. The scraper head 5-1 is fixedly mounted on the front end of the rotating rod, the tail handle 5-2 is arranged at the tail end of the rotating rod, and the tail handle 5-2 exposes the outer cylinder so that people can operate the tail handle 5-2, and the tail handle 5-2 can be rotated to The handle can drive the rotating rod 5 and the scraper head 5-1 to rotate synchronously, so that the scraper head 5-1 can scrape the lens of the endoscope, thereby scraping o...

Abstract

The invention discloses a special visual inseminating syringe for equus animals and an artificial insemination method thereof. The syringe comprises an outer barrel, an inseminating tube, an endoscopeand an inflation device, wherein the outer barrel is internally provided with an endoscope mounting channel and a working channel for inserting the inseminating tube; the inseminating tube comprisesan outer-layer hose and a rigid inner core; a sperm outlet through hole is formed in the front end of the outer-layer hose; the rigid inner core is arranged in the outer-layer hose and is in sliding match with the outer-layer hose; the rigid inner core can be pulled out from the tail part of the outer-layer hose; an air channel of the inflation device is communicated with a working channel in theouter barrel. The inseminating syringe disclosed by the invention is used for carrying out artificial insemination and an arm does not need to enter a genital tract of an estrous female animal, so that the simulation to vaginas and uterine cervixes is remarkably reduced; urination of the inseminated female animal is not caused, and the ovulation of the female animal and the quality of c are also not influenced, so that the probability of combining sperms and the ova and the quality of the ova are increased and the cycle conception rate of the artificial insemination is improved.

Description

technical field [0001] The invention belongs to the technical field of animal artificial insemination, and in particular relates to a special visual insemination device for equine animals and an artificial insemination method thereof. Background technique [0002] Due to the development and wide application of artificial insemination technology for animals such as cattle and pigs, people think that the artificial insemination technology of horses and donkeys is also very mature, but in fact the conception rate of artificial insemination of horses and donkeys is not high. The pregnancy rate in estrus is 70%-80% and 30%-50% in horses, and 30%-50% and 0-36% in donkeys. Especially donkeys, the conception rate of artificial insemination is still very unsatisfactory, even compared with the horse of the same genus Equus, there is still a big difference. There are many reasons for the low conception rate of artificial insemination of equine animals, such as the structural character...
