In recent years the employment of caesarian section in the bovine has been increasingly popular and with good reason. Though spectacular, it is very quickly and easily done and has a very good prognosis if done on subjects which lend themselves to surgery. In dealing with a live fetus and a strong healthy dam, the incidence of successful operations should approach 90 to 95 percent. In the absence of contraindications, whenever one encounters a small pelvic outlet, hydrops amnii, an unusually large fetus or torsion of the uterus that cannot be corrected, caesarian section should be considered at once.
