2 6o DISEASES OF THE DOMESTIC ANIMALS 



obtained from cows tuberculosis-free, as shown by the tuberculin 

 test. This custom will spon more generally prevail. The same 

 applies to cream, and milk used fpr cheese and butter making. 

 Tubercle bacilli are fourjd in both and will. retain their pathogenic 

 virulence three months even in salted butter. It has been. estimated 

 that tubercle bacilli may be present in 25 per cent., of butter as it is 

 found in 25 per cent, of separator slime (Schroeder & Cotton). 



The barn in which tuberculous animals have lived .must be 

 thoroughly cleaned, washed and disinfected before healthy stock 

 are placed in it. The floors, stalls and feed-boxes should also be 

 washed or sprayed with three per cent, formalin, or five per cent, 

 carbolic acid solution. ,Whitewash, in which is incorporated five 

 per cent, chlorinated lime, should then be applied. Five per cent, 

 solution of chlorinated lime should be used on the floors as well. 



Tympanites — Acute Meteorism or Hoven — Gaseous distension of 

 the Rumen in Cattle or Sheep. 



This form of indigestion often comes on suddenly and, in 

 acute cases, the animal may die within. an hour or two. The danger 

 is proportionate to the rapidity of development of the conditon. 

 The most frequent cause is a sudden change in food from dry to 

 green fodder, especially to clover and lush grass. 



Symptoms. — There is at first restlessness, eructation qf ga.s, 

 cessation of feeding and anxiety. Distension appears in the flanks, 

 more marked in the left over the rumen. On examining this region, 

 no peristaltic sounds are heard or movements felt. The distended 

 rumen presses on the diaphragm and disturbs trje breathing, which 

 becomes hurried and difficult. The nostrils are dilated, the animal 

 stands with fore feet apart and struggles for breath until— in 

 fatal cases— it falls and dies of asphyxia. 



Treatment. — This consists in active massage of .the left flank 

 to excite ,peristalsis and expulsion of gas. Massage is safer and 

 more efficient than exercising the animals. The passage of a
