Twentieth Annual Report on 



Eradication of Pullorum Disease 



in Massachusetts 



By the Poultry Disease Control Laboratory 



This bulletin reports results of pullorum disease testing for the 1939-40 

 season. A marked increase in the number of tests was observed for the 

 season. Increases in the number of tested turkey flocks and turkeys were 

 also noted. In six of the twelve counties, the tested chicken flocks re- 

 vealed no reactors. This fact shows that poultrymen in Massachusetts 

 are making definite progress in eradicating the disease and establishing 

 and maintaining pullorum-free flocks.
