Comparison of 1939-40 and 1940-41 Testing 



Table 5 gives a comparison of the 1939-40 and 1940-41 testing results 

 for the different counties. Fewer flocks, birds, and samples were tested 

 during the past year than in 1939-40. The decrease in birds and tests is 

 largely accounted for by one large flock which was tested only partially. 

 Aside from this the number of tested birds and tests in the various coun- 

 ties has changed only slightly when compared with 1939-40. The per- 

 centage of infection was less in those counties which revealed infection 

 during the previous season. The number of non-reacting flocks is less for 

 1940-41, but the number of birds in those flocks is approximately the 

 same as in the previous season. The average percentage of infection for 

 the State as a whole was reduced from 0.51 to 0.09 which is the lowest in 

 the testing history.
