CONTROL OF BACILLARY WHITE 

 DIARRHOEA 



1926-1927 

 By HENRY VAN ROEKEL 



In this bulletin a brief report is presented on the control of bacillary 

 white diarrhoea of poultry for the 1926-1927 testing season. A total of 

 127,327 birds was tested in this season as compared with 67,919 for the pre- 

 vious season, 1925-1926. This large increase shows that more poultrymen 

 are coming to realize the value of this test in the control and eradication 

 cf bacillary white diarrhoea. Of the 249 flocks tested, 114 were found free 

 from infection. Of the 127,327 birds tested, 4.03 per cent were infected.
