of testing all birds on the premises. Partially tested flocks are not eligible for 

 ofiScial recognition in Massachusetts. Five counties, Barnstable, Dukes, Franklin, 

 Hampshire, and Plymouth, had all their flocks classified as negative at the end 

 of the testing season 



Eighteen flocks, representing 34,105 birds, were classified as positive. The 

 number of positive flocks and birds in those flocks was less than in the previous 

 season. 



While Massachusetts flock owners have made outstanding progress in estab- 

 lishing and maintaining pullorum-free flocks, there is still need for improving 

 the industry's status in regard to freedom from pullorum disease. Annual 100 

 percent testing, careful selection from known pullorum-free flocks, and continual 

 observance of effective preventive measures should enable all poultrymen to 

 establish and maintain k pullorum-free flock. 



COMPARISON OF THE 1946-47 AND 1947-48 TESTING 



Table 5 shows a decrease in the number of tested flocks, but an increase in the 

 number of tested birds. Furthermore the percentage of reactors was less in 

 1947-48 than in 1946-47.
