At the close of the season, only six flocks, representing 19,472 birds, were classi- 

 fied as infected. Of these flocks, four were 100 percent tested, and two partially 

 tested. Positive flocks were identified in Berkshire, Franklin, Hampshire, 

 Middlesex, and Worcester Counties. 



These results suggest that pullorum infection is gradually being reduced and 

 eliminated from Massachusetts flocks. Owners of infected flocks are urged to 

 adopt effective measures towards establishing pullorum-free flocks. 



COMPARISON OF 1949-50 AND 1950-51 TESTING 



Table 5 lists a comparison of the testing data for the past two seasons. In 

 seven counties more birds were tested, whereas in six counties less birds were 

 tested than in 1949-50. The percentage of infection was slightly less than that 

 of the previous season. In seven counties no reactors were detected. The num- 

 ber of nonreacting flocks was less than in the previous season. It is hoped that 

 pullorum infection can be eliminated completely and that all tested flocks will 

 qualify for the pullorum-free grades.
