Eleventh Annual Report on 



Eradication of PuUorum Disease 



in Massachusetts 



By H. Van Roekel 



This bulletin includes a brief discussion of pullorum disease and progress 

 in its eradication. The motive of the eradication program is the estab- 

 lishment and maintenance of pullorum disease-free flocks in Massachusetts. 

 This may be accomplished if pouiltrymen understand the nature of the 

 disease and if they adopt effective eradication and prevention measures.
