Non-reacting and Positive Flocks Classified by Counties 



The distribution of non-reacting and positive flocks among the 12 coun- 

 ties is of interest. Table 4 shows that all 12 counties contained non- 

 reacting flocks. Worcester and Middlesex counties led in the number of 

 non-reacting flocks and birds. All flocks tested in 7 counties (Barnstable, 

 Dukes, Essex, Hampden, Hampshire, Plymouth, and Worcester) were 

 classified as non-reacting at the close of the season. 



During the past year, 332 non-reacting flocks (including partially 

 tested), representing 497,356 birds, were identified in the 12 counties. This 

 number of birds in non-reacting flocks represents an increase over the 

 previous season, which means that Massachusetts is making definite 

 progress in establishing a larger nucleus of breeding birds which are free 

 from pullorum disease. 



The 14 positive flocks were confined to 5 counties. These positive 

 flocks have been discussed elsewhere in this bulletin. Suffice it .to say 

 here that it is hoped that all possible agencies in the counties where the 

 positive flocks exist will aid the flock owners in eliminating the infection 

 from their premises. In the light of the possible ways in which pullorum 

 disease can be eradicated, no flock owner who is willing and conscientious 

 should regard the task of establishing a clean flock as impossible.
