CONTROL SERIES BULLETIN NO. 134 JULY, 1947 



Twenty-seventh Annual Report of 



Pullorum Disease Eradication 



in Massachusetts 



By the Poultry Disease Control Laboratory 



A total of 1,271,378 samples, representing 651 chicken and turkey flocks, was 

 tested during the 1946-47 testing season. The average percentage of positive 

 tests was 0.13. A slight increase in the volume of testing over the previous 

 season was noted. It is gratifying to observe that 95 percent of all the birds 

 tested are in 100 percent tested non-reacting flocks. The Massachusetts poultry 

 industry is to be complimented upon having such a large percentage of birds in 

 non-reaciing flocks.
