CONTROL SERIES BULLETIN No. 43 JULY, 1928 



Control of Salmonella PuUorum 

 Infection 



(Bacillary White Diarrhea) 

 1927-1928 



By W. R. Hinshaw and E. F. Sanders 



This is the eighth annual report on the control of bacillary white diarrhea 

 under the Poultry Disease Elimination Law. 



During the 1927-28 season, 232,091 tests were made on a total of 190- 

 658 birds in 321 flocks. In 1926-27 the total number of tests made was 

 127,327 in 249 flocks. 



A total of 138 non-reacting flocks, comprising 80,829 birds, are reported. 

 In 85 of these flocks every bird on the farm was tested, representing a 

 total of 58,263 birds. 



An effort is being made to encourage annual total flock testing, since 

 non-consecutive "sample" or partial testing has proven to be a failure as an 

 eradication plan. 



Requests for bulletins should be addressed to the 



Agricultural Experiment Station, 

 Amherst, Mass.
