COMMON DISEASES OF SWINE 335 



unsanitary conditions in the pen may also be a cause. A cough, 

 fever, and hurried or labored respiration are among the 

 symptoms. 



About all the farmer can do is to aim to prevent the disease. 

 If he has a case to deal with, careful nursing is the main thing. 

 Comfortable, well-ventilated quarters, and a light, sloppy diet 

 are important Daily doses of castor oil will help keep the 

 bowels active, and if the weather is cold the animal should be 

 kept covered with a blanket. Treatment is not very satisfactory, 

 as it is difficult to nurse a very sick pig.

" Statistics show that when there were over 56,000,000 

 hogs in this country, their value at that time was over 

 $339,000,000. Federal inspection at the abattoirs of the coun- 

 try, show two per cent of the hogs slaughtered to be affected 

 with tuberculosis. Reports from Europe show a far more wide- 

 spread infection, that runs from 5.5 to 7.5 per cent." 



" Hogs from Arkansas, Oklahoma, and Texas are remark- 

 ably free from tuberculosis, due to the methods of caring for 

 them, or rather the lack of care. They are not restricted to 

 feed-lots, where disease is commonly found, but roam over 

 large areas to shift for themselves. ~No prolonged feeding is 

 practised in narrow limits, but from birth to maturity they 

 are pastured on alfalfa, oats, corn, rape, and peanuts. ... In
