NON-REACTING AND POSITIVE FLOCKS CLASSIFIED BY COUNTIES 



In Table 4 the non-reacting and positive flocks are listed by counties. A total 

 of 515 flocks, representing 1,098,417 birds, was 100 percent tested and non-re- 

 acting. Nineteen flocks, representing 13,626 birds were partially tested and 

 negative. Middlesex, Worcester, and Plymouth counties have the largest num- 

 ber of birds in non-reacting flocks. Five counties, Berkshire, Dukes, Franklin, 

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

 the testing season. 



Twenty-eight flocks, representing 44,104 birds, were classified as positive. 

 The number of positive flocks, and birds in those flocks, was slightly larger than 

 in the previous season. With economic and working conditions returning to 

 peace time status, it is hoped that the flock owners will be in a better position to 

 maintain conditions which are conducive towards establishing and maintaining 

 flocks free of pullorum disease. The flock owner and hatcheryman should recog- 

 nize that they share the greater part of the responsibility for establishing and 

 maintaining flocks free of pullorum disease. It is hoped that Massachusetts 

 flock owners will strive to still further reduce the number of infected flocks in 

 the State.
