HOW TO DISTINGUISH IT FROM WHITE DIARRHOEA 



Ordinnry diarrhoea can nQt be distinguished from white diarrhoea 

 except by bacierioiogical examination. Such a diagnosis is gladly made 

 by most experiment station or agricultural college bacteriologists. One 

 or more effected birds should be properly crated and shipped with trans- 

 portation charges prepaid. Such a diagnosis will aid in future treat- 

 ments.

 However, people often confuse ordinary diarrhoea and white diarrhoea 

 and thereby lose a whole flock of chicks. Ordinary diarrhoea can of-

 advantage of this fact and give treatments which stops the disease, sup- 

 posed to have been white diarrhoea. White diarrhoea is a germ disease 

 which lives from year to year in the ovaries of chicks that recover and 

 is thrown out in about 25 per cent of the eggs laid by effected hens. A 

 hen so effected seldom gives the disease to other healthy hens of a flock. 

 However, chicks hatched from infected eggs usually develop the disease 

 in from 2 days to six weeks after they are hatched. Such effected chicks 

 should have a hole punched in the web of the foot if they recover and
