fectant, the syringe being filled with serum before the needle is re- 

 placed. If the nozzle of the syringe becomes soiled, it should be 

 washed thoroughly before further use. Cleanliness will reduce the 

 possibility of abscesses and blood poisoning. 



Sufficient help should be provided to hold the hogs in proper posi- 

 tion for treatment. Large hogs that are too heavy to handle in any 

 other way may be snared by the upper jaw and snubbed to a post. In 

 such cases the injection is made beneath the skin back of the ear (fig. 

 8). Hogs of ordinary size may be handled conveniently in a V- 

 shaped trough (fig. 9) or on a small platform slightly elevated from 

 the floor. This places the hog in a position for making the injection 

 between the foreleg and the body, which is regarded by many as the

most desirable location. Small pigs and shoats up to 75 or 80 pounds 

 usually are held up by the hind legs and the injection is made beneath 

 the skin into the loose tissues of the flank (fig. 10). This is the most 

 convenient and rapid way of handling small pigs, as they may be 

 held by one man and are in a suitable position for taking the tem- 

 peratures. Injection into the ham should be avoided, particularly 

 in grown hogs that are to be placed on the market before they have 

 time to recover fully from the injection, as abscesses may develop and 

 remain undiscovered until the ham is cured and placed on the market. 



The temperatures of all hogs should be taken and recorded before 

 they are treated, and those showing high temperatures — that is, 

 above 101° F. — should be marked so that they may be identified after
