DISEASES OF THE DOMESTIC ANIMALS 827 



an outdoor life, or one in clean, well-ventilated and uncrowded 

 stables. The sick should be isolated and Isilled, or Bang's segrega- 

 tion method may be used. Cows showing marked physical signs of 

 tuberculosis should be killed — ^particularly of the lungs, uterus and 

 udder. Animals reacting to tuberculin test should be isolated; their 

 calves removed to separate farm, barn, or partitioned portion of 

 same barn. Calves fed from mother on day of birth, thereafter on 

 boiled milk fromi same, or milk from healthy cows. Two sets of 

 employees if possible. If not, then the healthy animals should be 

 first tended, and the overalls and shoes should be changed before 

 tending the tuberculous. Also there must be separate utensils for 

 the healthy and tuberculous. The healthy and sick should be 

 separated in pasture. The healthy animals must be tuberculin 

 tested every six months, as usual. The infected barn should be 

 washed and cleaned and sprayed with 3% formalin, or 1-SOO corro- 

 sive sublimate solution, on the walls, floors, and feed boxes; the 

 floors should be covered with quicklime; and the premises then dis- 

 infected with formalin or sulphur vapor. The tuberculin test must 

 be applied to all newly-bought animals, before they are included in 

 the herd, and the whole herd should be tuberculin-tested twice a 

 year. Raw milk from tuberculous cows is unfit for food and is a 

 means of transmitting the disease to man, especially to infants. 

 Von Behring's Bovovaccine — of dry, living, tubercle bacilli of the 

 human type — appears to confer immunity, for a more or less indefi- 

 nite period, in cattle. It is indicated for injection into young 

 animals, as a preventive agent, when tuberculosis is prevalent in a 

 herd. Its value is stiU a matter for the future to determine. 



Tympanites, Acute (In Cattle and Sheep). 



Gaseous distension of the rumen is common in sudden changes of 

 diet from dry fodder to clover or lush grass. Perform active mas- 

 sage of the left flank. Pass a stomach tube. To stimulate peristalis, 

 throw a stream of cold water against the left flank, and give com- 

 pound spirit of ether, 393, internally. With increasing distension, 

 plunge a knife, or, better, a trocar and canula, into the most 

 prominent part of the left flank, midway between the angle of the 

 hip and last rib. Compress the tissues about the canula, to prevent 

 gas and food from entering the tissues. The canula may be left in 

 place 24 to 48 hours and the animal should receive but little food- 

 hay and bran mash. If the rumen is impacted, see Indigestion.
