Daily irrigations of the uterus with nonirritating antiseptic solutions, such as 0.5 per cent solution of cresol or compound solution of cresol, at body temperature have a tendency to prevent the multiplication of microorganisms in the uterus and in this way promote recovery. Douching of the uterus should be continued until the discharge ceases. In addition, the external genitals, root of the tail, escutcheon, etc., should be sponged daily with the antiseptic solution. Aim to place all pregnant animals in disinfected individual pens or stalls a few days before they are expected to calve, and confine them to these quarters for three or four weeks following the delivery of the calf, or as long thereafter as uterine discharges are observed. Avoid carrying infection from the maternity stalls to other portions of stable, on shoes or otherwise. This may be prevented to some degree by the use of disinfectant solutions on shoes after the stalls have been entered or by wearing rubbers while in the maternity stalls, removing them after the isolated animals have been attended to. The isolation of cows at time of calving and the aborting animal is based upon the knowledge that the fetus, afterbirth, and uterine discharges of an affected animal at these times very frequently contain myriads of the abortion bacteria, and that unless these substances are confined and promptly destroyed an abundant opportunity is provided for the contamination of the food substances of the healthy animals and their contraction of the disease. Refrain from breeding fresh cows for a period of six weeks to two months following calving. The aborting animal should be isolated for a period of six weeks to two months and under no consideration be permitted to mingle with the rest of the herd as long as uterine discharges are observed. Douching of the external genitals of the bull, a practice formerly regarded as highly important for preventing the spread of the disease, is now recognized as being of doubtful value. The bull is protected from abortion infection to a great degree by permitting him to serve only such animals as have calved or aborted from six weeks to two months previously. Investigational work has indicated that when the bull is affected with the disease the organs of his generative system commonly involved are not reached by the antiseptic solutions. A more rational method for the prevention of the spread of the disease by the bull consists in keeping him in an inclosure separate from the females and in having all services take place on neutral ground. Great care should be used in purchasing cattle, and cows not known to be free from the disease should be kept in separate quarters until this point is determined.
