If it happens while the calf is still in the womb, it will usually bleed freely and continuously until the fetus has been extracted, so that the womb can contract on itself and expel its excess of blood. Another danger is that in case of a large rent the calf may escape into the cavity of the abdomen and parturition become impossible. Still another danger is that of the introduction of septic germs and the setting up of a fatal inflammation of the lining membrane of the belly (peritoneum). Still another is the escape of the small intestine through the rent and on through the vagina and vulva, so as to protrude externally and receive perhaps fatal injuries. In case of rupture before calving, that act should be completed as rapidly and carefully as possible, the fetal membranes removed, and the contraction of the womb sought by dashing cold water on the loins, the right flank, or the vulva. If the calf has escaped into the abdomen and can not be brought through the natural channels, it may be permissible to fix the animal and extract it through the side, as in the CÊsarian section. If the laceration has happened during eversion of the womb it is usually less redoubtable, because the womb contracts more readily under the stimulus of the cold air so recently applied. In case the abdomen has been laid open it is well to stitch up the rent, but if not, it should be left to nature, and will often heal satisfactorily, the cow even breeding successfully in after years. Rupture of the floor of the vagina has been already referred to as allowing the protrusion of the bladder. Laceration of the roof of this passage is also met with as the result of deviations of the hind limbs and feet upward when the calf lies on its back. In some such cases the opening passes clear into the rectum, or the foot may even pass out through the anus, so that that opening and the vulva are laid open into one. Simple, superficial lacerations of the vaginal walls are not usually serious, and heal readily unless septic inflammation sets in, in which case the cow is liable to perish. They may be treated with soothing and antiseptic injections, such as carbolic acid, 1 dram; water, 1 quart.
