DISEASES OF SWINE TREATMENT 269 



the sow before farrowing. Coughing, especially in the morning when the pig 

 comes from his bed ; jerking of body, and the pig may fall to the ground. 

 Cold water and rubbing will aid in recovery. 



Treatment. In case the pigs are too fat, the sow should be taken from 

 them for a while during each day. Proper and plenty of exercise will do wonders 

 towards keeping the litter in good condition. At the first sign of thumps all 

 of the pigs should be treated the same, as they are all subject to the same 

 condition. Eggs and milk with bran added and thrown into the trough will 

 help much in the treatment of this disease. Pigs that are given lumps of tar 

 several times will react satisfactorily. 



Mix a little tartar-emetic with the drinking water or with the milk for 

 from five to ten days. 



Tuberculosis. 



Tuberculosis in hogs is closely associated with the same malady in cattle. 

 It is caused by germs or bacteria and affects the various organs of swine; 

 feeding unpasteurized skimmed milk; allowing hogs to run behind tubercu- 

 lous cattle and feed upon the undigested grain in the manure; feeding un- 

 cooked carcasses of other animals that contain tuberculosis germs ; consump- 

 tive attendants ; and eating carcasses of tuberculous fowls. 



Symptoms. The symptoms of tuberculosis have no very decided char- 

 acteristics. In intestinal tuberculosis there is often a general disturbance of 

 the digestive functions and diarrhea or constipation may result. In advanced 

 tuberculosis of the lungs there is a dry, persistent, harsh cough and rapid 

 breathing, especially when exercised. The cough cannot be distinguished 

 from that caused by lung worms. In severe cases of the disease there may 

 be continued falling away and weakness. Most cases of tuberculosis are not 

 recognized until the hogs are killed. In cases where the disease can not be 

 told by the symptoms exhibited, the tuberculin test is recommended which 

 makes it possible to detect the disease in its early stages and to stamp it out 

 by killing the affected animals. 



Tuberculin Test. The intradermal method of using the tuberculin test 

 has given excellent results on hogs. Full credit for the perfecting of this test 

 should go to the Animal Industry Bureau, Washington, D. C, and State Ex- 

 periment Stations. In this method two drops of tuberculin is used. This is 

 prepared by evaporating away two-thirds of the volume of the tuberculin 

 obtained from the Bureau mentioned above for the subcutaneous tuberculin 

 testing of cattle. It is injected into the skin, not under it, near the base of 

 one of the hog's ears. If the hog is affected with tuberculosis, the ear will 

 swell near where the injection was made in about forty-eight hours and will 

 remain swollen from 10 to 12 days. If there is no infection no reaction will 

 take place. 



Treatment. By applying the tuberculin test when tuberculosis in sus- 

 pected, the diseased hogs can be determined and killed before the whole herd 

 is affected and the hog raiser can thus clean up his herd with as little loss 

 as possible. After removing the diseased animals the place may be thor-
