Comparison of 1937-38 and 1938-39 Testing 



Table 6 gives a comparison of the 1937-38 and 1938-39 testing results. Nine 

 counties showed an increase in the number of tested flocks and 11 counties had 

 an increase in tested birds. The average percentages of positive tests increased 

 in 6 counties, decreased in 3, and remained unchanged in 2. One county had no 

 testing the previous season. The number of non-reacting flocks increased in 9 

 counties. 



For the State as a whole, increases were observed in tested flocks (47), tested 

 birds (90,838), tests (117,436), and non-reacting flocks (41). The average per- 

 centage of infection increased from 0.17 to 0.34.
