Swine Erysipelas. 



[FEB., 



2. Should the disease appear, however, all the pigs should, 

 with the least possible delay, receive a dose of serum, and 

 those in which the temperature is normal should be removed 

 to non-infected styes on the same premises, if this be prac- 

 ticable. Ten days afterwards the vaccination proper may be 

 practised after the method of Leclainche (serum and virus, 

 then virus alone) on those animals still showing a normal 

 temperature. The pigs with high temperatures should be 

 returned to the infected styes, and if their value warrants 

 it they should be treated by injections of serum alone. On 

 no account should they receive the culture. If it be found 

 impossible to separate the sick from the healthy the opera- 

 tions should be carried on in the infected styes. 



3. Although this disease can to a large extent be success- 

 fully combated by inoculation, it must not be thought that 

 measures of isolation and sanitation can be dispensed with. 

 While the outbreak lasts no new pigs should be brought in, 

 and none should leave the premises except for slaughter 

 under the most rigorous precautions against the disease being 

 conveyed to other premises. If a pig owner finds that the 

 disease reappears annually on his premises he should resort 

 annually to preventive inoculation, timing the operation so 

 as to have his animals immunised before the season of 

 greatest activity. He should also remember that the com- 

 plete eradication of the disease from his premises will be 

 greatly facilitated by keeping his pigs in styes which can be 

 properly disinfected. 



Although swine erysipelas can hardly be regarded as a 

 very fatal disease of pigs, in Great Britain at least, the Board 

 have been informed that it often interferes materially with 

 the marketing of pigs, since it frequently attacks them and 

 causes considerable emaciation close to the time when they 

 are expected to be ready for market. In such cases owners 

 have been advised to immunise their pigs by methods of 

 inoculation about three months before they are expecting 

 them to be ready for market. From information received 

 from those who have put this advice into practice, it would 

 appear that the adoption of preventive inoculation has given 

 excellent results.
