TUBERCULOSIS 529 



Symptoms. — The symptoms of tuberculosis depend 

 upon the stage of the disease. The earliest symptom 

 is a short, dry cough frequently repeated, especially in 

 the morning, and while feeding. By-and-bye, accord- 

 ing to the activity of the disease, there is wasting, 

 enlargement of the cervical glands, hidebound, and 

 a dirty pale colour of skin. The breath is generally 

 bad, the eyes dull and sunken in their orbits, the 

 appetite is frequently good, and the secretion 

 of milk considerable ; in other cases, fastidious ap- 

 petite and almost no secretion of milk. Abnormal 

 sounds are heard on auscultation, and dullness on 

 percussion. 



If the udder is invaded, nodules are felt, which are 

 hard and painful to pressure, but must be distinguished 

 from the indurations produced by simple inflammation 

 in cases of mammitis. 



In doubtful cases, or in those cases where it is de- 

 sirable to ascertain if there are any of the herd 

 affected with tuberculosis, injections of '* tuberculine '' 

 should be made ; but as this is an operation which 

 should be conducted by a member of the veterinary 

 profession, we shall not enter into details. 



Remedies. — Where tuberculosis exists in a herd 

 of valuable breeding animals, in order to get rid of 

 the disease, it is not imperative to slaughter all of 

 them. Those markedly affected should be slaughtered, 

 and thereafter the remaining animals (young and old 

 alike) should be subjected to the tuberculine test. 

 Having by this test divided the herd into affected and 

 non-affected animals, then house and graze the two 

 sections apart. At stated intervals re-apply the 

 tuberculine test, and add any re-acting animals to the 

 affected section. The calves of the whole herd to be 

 removed from their mothers as soon as born, and hand-
