ABSTRACT:
An artificial insemination (AI) device for the insemination of bovines and other animals including three hollow and essentially cylindrical tubular elements. Each element is provided with an open proximal and an open distal end, the three elements being: an outer protective sheath, an inner sheath, and a semen tube, whereby the diameter of the elements is such that the inner sheath is axially movable in the outer protective sheath and the semen tube is axially movable 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. An outer sheath, an inner sheath and a semen tube for use in an AI device and a method for the insemination of bovines and other animals, includes 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 the tubular element by protrusion of an inner tubular element and manually guiding 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.
