DEVICE AND METHOD FOR ARTIFICIAL INSEMINATION OF BOVINES AND OTHER ANIMALS

摘要

The invention relates to an artificial insemination device for the insemination of bovines and other animals comprising three hollow and essentially cylindrical tubular elements, each element is provided with an open proximal and a open distal end, said three elements being: an outer protective sheath, an inner sheath, anda semen tube,whereby the diameter of said elements is such that the inner sheath is axial movably in the outer protective sheath and the semen tube is axial movably in the inner sheath, whereby the length of the outer sheath is less than the length of the inner sheath and whereby the inner sheath and the semen tube are jointly axially displaceable in and through the outer sheath. The invention further relates to an outer sheath, an inner sheath and a semen tube for use in an AI device and to a method for the insemination of bovines and other animals, comprising the steps of inserting through the cervix and into the uterine horn, a closed tubular element to a point near the major curve of the horn, opening said tubular element by protrusion of an inner tubular element and provide manual guidance to it into the curve of the horn and positioning the distal end of the inner tubular element near the ovary, and further providing semen nearby the UTJ through an internal semen channel.
