ANTI-HOG CHOLERA SERUM. 



For the past two years the !N'orth Carolina Department of Agricul- 

 ture has been preparing and distributing, through the State Veteri- 

 narian, Anti-Hog Cholera Serum. This serum is sent to the farmers 

 of this State when they report an outbreak of Cholera on their farm or 

 on farms in their vicinity. 



As the name will indicate, Anti-Hog Cholera Serum is a preventive 

 and not a curative measure of Hog Cholera. It would be useless to 

 inject hogs with the serum after they have shown symptoms of the 

 disease. When an outbreak of Cholera appears in a herd, if the well 

 hogs are treated, one is able to prevent them from developing Cholera 

 if this is done before they show any symptoms of the disease. 



It is not the purpose of this article to go into a discussion of the 

 symptoms of Hog Cholera, but it is for the purpose that the people in 

 the State may know where they can secure Anti-Hog Cholera Serum 

 when they are in need of it. "We are also giving the doses for the differ- 

 ent weight of hogs so that in ordering the serum one may know what 

 amount they will need. The doses for the different weights of hogs are 

 as follows : 



Weight. Number of Cubic Centimeters. 



20 lbs. to 100 lbs 20 Cc. 



100 lbs. to 150 lbs 20 Cc. to 30 Cc. 



150 lbs. to 200 lbs 30 Cc. to 40 Cc. 



200 lbs. to 300 lbs 40 Cc. to 60 Cc. 



300 lbs. to 400 lbs 60 Cc. to 80 Cc. 



The above is the amount of serum to be injected as a preventive 

 and if there is a very virulent form of Cholera in a herd it would be 

 advisable to increase this dose from 5 Cc to 10 Cc for each injection. 



To make the injection it is necessary for one to have a hypodermic 

 syringe. A 20 Cc syringe is preferable. The injection should be made 

 deep into the muscles on the inside of the thigh after cleansing that 

 portion with five per cent solution of carbolic acid or some other disin- 

 fectant. However, this injection can be made into the muscles of the 

 neck with as satisfactory results. 



Hogs of all ages and under all conditions can be injected with serum 

 without any ill results, as the only ill effect ever seen following injection 

 of serum is the formation of small abces'ses at the point of injection, and 

 this is due to infection and not to the serum. This can be largely avoided 

 by having the syringe sterilized and keeping the hog in a clean, dry 

 place from one to two days following the injection. 



We are trying to keep a sufficient amount of serum on hand at all 

 times to meet the demand of this State. We also keep on hand a supply 

 of 20 Cc hypodermic syringes which we are glad to send with the order, 

 if requested, for $1.75 — just the cost. We are now charging 2c. per Cc 

 for the serum and only send the serum by express C. O. D. unless we 

 receive check with the order.
