Table 6. — Twenty- Four- Year Pullorum Disease Testing Summary 



*Based on total birds tested: 1927-28, 190.658 birds; 1928-29. 254.512 birds. 



Testing All Birds on Premises: This past year 41 flock owners (9.92 percent) 

 had only part of their flocks tested, compared with 7.53 percent the previous 

 season. While no reactors were found in the majority of these partially tested 

 flocks, they were not eligible for oflficlal recognition because it is impossible to 

 determine the true pullorum status of all birds on the premises by testing only 

 part of the flock. Flock owners, therefore, should strive to test their entire 

 flock if any testing is to be done. This would enable them to determine the 

 true status of the flocks, permit official recognition of the flocks if negative, and 

 without question increase the sales possibilities of their stock. 



Early Testing: During the last three years the laboratory has had increasing 

 difficulty in finding temporary help to assist with the field and laboratory work. 

 It is exceedingly difficult to interest competent persons In short-term employ- 

 ment. The bulk of the testing work comes In October, November, December, 

 and January. The following summary will point out the situation more clearly.
