. The diseases of the genital organs of domestic animals. Horses; Genital Diseases, Male -- veterinary; Genital Diseases, Female -- veterinary. 174 Diseases of the Genital Organs B. Ventral Hernia Large ventral herniae, such as indicated in Fig. 58, also inhibit copulation, rendering the bull worthless as a â PlG. 58âLarge Ventral Hernia preventing Coitus. C. Horizontal Vulva Horizontal vulva in the cow sometimes serves to render copulation difficult or impossible. In aged cows with pen- dulous abdomen and low back (lordosis, or sway-back) the superior commissure of the vulva is depressed and dragged downward and forward by the descent of the rectum and anus, so that the vulvar opening is directed upward. More rarely, the vulvar opening is directed upward in otherwise well-formed heifers, as a peculiarity in conformation. When the bull attempts to copulate with such an animal, the penis tends to glide over the vulva and strike against the anal re- gion. This is best avoided by causing the female to stand with her hind feet in a pit or depression, with the fore feet.
