be transmitted through the food during the first 

 three or four days of the chick's life. 



"Prevention. Since the disease cannot appar- 

 ently be transmitted through the food supply after 

 the chicks have reached the age of three or four days, 

 every means should be pursued to prevent the spread 

 of the infection during this critical period. We sug- 

 gest the segregation of the chicks in small lots during 

 this interval; perfect disinfection and cleanliness of 

 brooders and brood coops; food and water supplied 

 in such a manner as to prevent contamination by 

 the droppings; the use in the brooder of a liberal 

 amount of fine absorptive litter which will quickly 

 cover and seal up the droppings. (For this purpose 

 we have used alfalfa meal with much satisfaction.) 



" Raise and maintain the vigor and vitality of the 

 breeding stock and chicks by every reasonable 

 means known to poultrymen. . . . 



"If the breeding stock proves infected there are 

 two courses of procedure open; (a) market the entire 

 flock or refrain from using their eggs for hatching or 

 (b) install trap nests in the breeding-pens . . and 

 ascertain which individual hens are producing 

 infected chicks, and remove them."
