Description
Technical Field
The utility model belongs to the technical field of animal artificial insemination, concretely relates to dedicated visual insemination ware of equus animal.
Background
Due to the development and wide application of the artificial insemination technology of animals such as cattle, pigs and the like, people think that the artificial insemination technology of horses and donkeys is mature, but in fact, the conception rate of the artificial insemination of the horses and the donkeys is not high, the conception rate of fresh semen and frozen semen in the estrus is 70% -80% and 30% -50% of the horses, and the conception rate of the fresh semen and the frozen semen in the donkeys is 30% -50% and 0-36%. Especially donkey, has a very unfavorable conception rate in artificial insemination, even if it is greatly different from horses belonging to the genus equine. The low conception rate of the equine artificial insemination is caused by a plurality of reasons, such as the structural characteristics of reproductive organs of the equine, the insemination time, the number of effective sperms input and the like, and is also related to insemination instruments and methods of the equine.
For equine, the artificial insemination method includes the steps of wearing a sterile long-arm glove, holding a rubber or plastic seminiferous duct by a hand, entering a vulva, continuing to enter a vagina forwards, touching the front end of the vagina with the hand to find a cervical orifice, then inserting the seminiferous duct into a uterine cavity, slightly retreating the seminiferous duct when the seminiferous duct is inserted forwards and is fixed, connecting a syringe at the rear end of the seminiferous duct, driving the seminiferous fluid into the uterus, sucking a small amount of air by the syringe, pushing the seminiferous duct into the uterus, retreating the seminiferous duct, massaging the cervical orifice with the hand to prevent the seminiferous fluid from flowing backwards. Such methods of insemination have a number of disadvantages: (1) the stimulation to the reproductive tract of the female animals is large, the female animals often have micturition reaction (even if little urine) after insemination, according to the observation, the micturition female donkey with the reaction reaches 80-90%, and urine examination of the insemination female donkey finds that 23.5% of urine of the insemination female donkey contains sperms, so the severity of semen backflow caused by micturition can be seen. The semen backflow caused by the urination will reduce the effective sperm number input into the uterus and reduce the estrus conception rate of animals. (2) The stress response of the animals is stronger, which may affect the ovulation time of the dam and even the quality of the ova. (3) This method of insemination is prone to infection of the reproductive tract, as it can easily cause damage to the uterus and vagina and can introduce microorganisms into the reproductive tract.
