NONREACTING FLOCKS CLASSIFIED BY COUNTIES 



This is the second consecutive year in the entire testing history that all tested 

 flocks have been classified as nonreacting. A total of 218 nonreacting flocks, rep- 

 resenting 944,955 birds, was identified in 11 counties as listed in Table 4. A total

of 208 flocks was 100 percent tested; whereas, 10 flocks were partially tested. The 

 latter group constituted 27,434 birds in seven counties. However, it is encouraging 

 thai 97.10 percent of all birds tested are in 100 percent nonreacting flocks, and 

 it is hoped that in the near future all flocks will be 100 percent tested. 



It was stated in previous sections that among all flocks tested only one reactor 

 was detected and it was identified in a small back-yard flock. The laboratory ap- 

 preciates the splendid cooperation received from the flock owners in the attempts to 

 eradicate the disease. It is hoped that flock owners will continue to cooperate to 

 the fullest extent in order^^that the disease may be eradicated from the Massachu- 

 setts poultry industry. 



COMPARISON OF THE 1957-58 AND 1958-59 TESTING 



Table 5 lists testing data for the two seasons. For the second consecutive year 

 fewer flocks, birds, and samples were tested than in the previous year. Only three 

 counties (Barnstable, Franklin, and Hampshire) revealed a slight increase; whereas, 

 the remaining eight counties had appreciable decreases. Middlesex, Plymouth, 

 and Worcester Counties revealed a decline of more than ten thousand birds. While 

 the results for the^two years differ only slightly it is apparent that continued pro- 

 gress is evident.
