PREVENTION, SYMPTOMS AND TREATMENT

the tongue is paralyzed, and the animal can not swallow. The move- 

 ments of the digestive organs cease and tympany results. The feces 

 are hard and often smeared with mucus or blood, and there is re- 

 tention of urine. . The pulse ranges from 60 to 120; the temperature 

 from subnormal to 105 F. The extremities are cold. 



Death commonly occurs within two or three days, rarely at 

 later periods, from food or drink getting into the trachea and caus- 

 ing foreign-body pneumonia. Occasionally the paralysis persists 

 a long time, but ordinarily recovery, when it takes place, is com- 

 plete within a few days. Sometimes the symptoms are of a mild 

 nature with weakness of the hind limbs, but no loss of deglutition 

 or peristalsis, in which case recovery is the rule. 



Preventive measures consist in exercise during pregnancy, with- 

 holding grain entirely, except bran mash and a little flaxseed meal 

 during the latter six weeks of pregnancy, and the use of Glauber's 

 salts to keep the bowels active. The after-birth should be removed 

 soon after calving, if not expelled spontaneously, and 2 per cent, 

 lysol douche used in the uterus. 



Treatment. — The recently discovered curative treatment is per- 

 haps the most brilliant in veterinary medicine. Over 90 per cent, 

 of patients are now cured, whereas formerly almost the reverse 

 was true. This curative treatment was first employed by Schmidt, 

 who injected into each quarter of the udder about y 2 pint of a 1 

 per cent, sterile solution of potassium iodide. Kunsel then used a 

 tank of compressed oxygen connected by six feet of rubber tubing 

 to a sterile milking tube. The hands of the operator, and the udder 

 of the patient, after being stripped of milk, should be thoroughly 

 washed with soap and warm water and 2 per cent, lysol (compound 

 cresol solution), and the milking tube boiled. The oxygen gas is 

 permitted to distend each quarter of the udder by flowing through 

 the tubing and milking tube into the teat. It has been found that 

 sterile air may be used for inflating the udder and will act as satis- 

 factorily as oxygen gas. Very convenient applicances are now sold,
