40 BOARD OF AGRICULTURE. [Sept., 



clone under clean surroundings. We selected a swill man's 

 pigpen for demonstration in which there were seventy-eight 

 hogs averaging eighty pounds each. They were fed the 

 morning we started to v\ork but should not have been. I 

 personally washed the pigs with soap and water, scraped 

 and painted with iodine, then after the inoculation placed 

 them in clean pastures. One little pig in that bunch had a 

 breach which was reduced and he came out all right. There 

 was cholera in that herd and they all came out withcTut an 

 abscess. That goes to show what can be done where cleanli- 

 ness prevails. This man is going into the swill-pig business 

 and expects great success. 



In a herd of from two thousand to three thousand hogs in 

 New Haven, six hundred and elcA'en were treated and the 

 little pigs as far down as fifteen pounds were given the double 

 treatment with wonderful success. I do not believe in double 

 treating the pig below thirty pounds, but would recommend 

 the single treatment for small swill-fed hogs, for the pro- 

 tection this treatment gives up to time of double treatment. 



For an illustration will take two farms : 



The first had six hundred seventy hogs, and the owner 

 went out and bought five new ones. The day after these 

 pigs were delivered one died, and a post mortem revealed the 

 presence of hog cholera. Two more of the lot died. We in- 

 jected the rest of the herd, even the little ones. This was on 

 a grain-fed herd where no swill had been fed previous to the 

 treatment. 



The owner of the second farm was a large hog raiser. He 

 purchased two hundred inoculated pigs from the \A'est, and 

 they did so well he went to Buft'alo and bought one thousand, 

 five hundred more and had them inoculated at considerable 

 expense. Something went wrong, and he brought these pigs 

 into his herd having only passive immunity. These pigs be- 

 gan to break and have all kinds of trouble. He injected the 

 whole bunch all over again and lost thirty per cent. We 

 finally cleaned them all up. He is going at it again next 

 spring. The point I wish to make is that there was not a 

 case of cholera until the rotten stock was brought in. 



Would you always inoculate? I look at it in this way: If 

 you have a farm with no hog cholera among the stock, or on
