Technical Field
The utility model belongs to the technical field of the artificial insemination of ewe, concretely relates to artificial insemination device is used to sheep.
Background
The Artificial Insemination (AI) technique for sheep is a scientific mating method which uses an instrument to collect semen of male animals, and uses the instrument to input the semen into a proper position of the reproductive tract of female animals after examination and treatment so as to make the female animals pregnant, thereby replacing natural mating of male and female animals. With the development of sheep raising industry and the popularization and utilization of excellent varieties, artificial insemination technology is adopted in more and more large-scale sheep raising farms. The artificial insemination of the sheep can not only improve the utilization rate and the hybridization rate of the stud ram and accelerate the improvement process of the sheep flock, but also effectively prevent the spread of diseases, save the cost for raising the stud ram and reduce the investment. However, the popularity of artificial insemination in sheep is far from reaching the level of cattle and pigs.
The wide application of the cattle artificial insemination technology benefits from a successful frozen semen technology and a rectum-held cervix deep insemination technology, but the sheep frozen semen technology is also successful, but the sheep frozen semen breeding conception rate is very low because the sheep can not implement the rectum-held cervix deep insemination technology. The use of the laparoscope uterine horn insemination technology can greatly improve the conception rate of sheep, but requires professional technicians to carry out minimally invasive surgery, which is not beneficial to social popularization. Meanwhile, the production cost of the frozen semen unit of the sheep is far higher than that of the cattle, the value of the sheep is far lower than that of the cattle, and the enthusiasm of using the frozen semen of the sheep is greatly reduced.
The general popularization of artificial insemination of pigs is due to the introduction of a whole set of foreign mature technologies in recent years, and the application of the disposable vas deferens and the semen storage bottle which are mainly suitable for the physiological condition of pig reproduction is realized.
