COMPARISON OF 1945-46 and 1946-47 TESTING 



Table 5 gives a comparison of the 1945-46 and 1946-47 testing results for the 

 different counties. Slight increases in the number of tested flocks, birds, tests, 

 and non-reacting flocks were noted in some counties, while in other counties de- 

 creases were observed. 



In 1946-47 the following increases were noted over the previous season: 24 

 flocks; 30,410 birds; 13,389 tests; and 21 non-reacting flocks. 



The data in Table 5 reveal that Massachusetts is continuing its progress in 

 eliminating pullorum disease from its flocks. 



TWENTY-SEVEN YEAR TESTING SUMMARY 



In Table 6 is given a twenty-seven year testing summary which shows con- 

 tinued progress in eliminating the disease from flocks. The percentage of positive 

 tests has not exceeded 0.13 in the last four years, which is the lowest four years in 

 the testing history of Massachusetts. Also the percentage of total tested birds 

 in non-reacting flocks has not been below 90 during the last seven years.
