THIRTY-YEAR TESTING SUMMARY 



Table 6 shows that a larger number of birds was tested this past year than in 

 any previous season. The general trend of progress for 1949-50 was about the 

 same as in the more recent years. 



Table 6. — Thirty- Year Pullorum Disease Testing Summary 



♦Based on total birds tested- 1927-28, 190,658 birds; 1928-29, 254,512 birds. 



COMMENTS AND SUGGESTIONS 



Annual Testing of All Birds on the Premises: In this report the importance 

 of annual testing of ail birds on the premises has been stressed repeatedly. It 

 was stated that 18.43 percent of the flocks tested in 1948-49 were not tested in 

 1949-50. The number of flocks that drop out each year far exceeds the number 

 of flocks which re-enter the program with an intermittent testing history. The 

 flocks which are in the program for just one year do not contribute to the goal 

 of eradication as much as flocks tested annually.
