504 DISEASES OF SWINE 



injections were given 4 of the check animals had died, and the 

 owner, fearing that they would all be lost, sold the remaining 11 

 to a local shipper. Had they been left on the farm the chances are 

 that nearly if not all of them would have died. 



It will be seen that in this herd the serum practically checked 

 the outbreak at once. Three hogs were quite sick on the day that 

 the herd was treated. Only 3 were lost afterward. If tempera- 

 tures had been taken, there is no question but what a large number 

 of the shoats which did not show visible signs of the disease would 

 have been found to be developing hog-cholera. 



The final report of this experiment gives a very good example 

 of one of the ways in which cholera is spread where no quarantine 

 regulations are applied to farms on which the disease exists. 

 Eleven exposed hogs were here sent to market and transported over 

 public highways and through public stock-yards. It is through this 

 manner of handUng the disease that cholera is able to get such a 

 quick, widespread distribution in a neighborhood or community. 

 Sick herds should be quarantined, and not allowed to pass over 

 public roadways to scatter infection to adjoining farms. 



Herd Number Forty-four. — This was another herd located in 

 the neighborhood of Herds Thirty-two and Forty-three. When 

 the Bureau Inspectors visited this farm they found things in a very 

 bad way. The animals were in such a serious condition, and the 

 disease had obtained such a headway, that it was hardly worth 

 while, apparently, to use any serum on them. The owner, however, 

 had seen the results obtained on other farms in the neighborhood, 

 and he was very anxious to have his hogs treated. Nearly all of 

 the hogs were sick at the time, and the symptoms were unmistak- 

 ably those of genuine hog-cholera. 



There were 17 shoats, averaging up to 100 pounds, in the herd. 

 Many of these shoats were visibly sick at the time. They were all 

 injected, however, receiving from 20 to 60 c.c. of the serum. 

 Fourteen small pigs, which were all more or less sick, were also 

 injected, receiving 10 c.c. each of serum. Two shoats and 5 small 

 pigs were left untreated, to serve as checks. 



Final report on this herd showed fairly good results. Twelve 

 of the treated shoats and one of the checks lived through. All of 

 the pigs, both treated and untreated, died. While this report is
