title: Vaccination for hemorrhagic enteritis of turkeys.
abstract: Laboratory and field evidence indicates that a safe and effective procedure has been developed for vaccinating turkey poults against hemorrhagic enteritis of turkeys. Vaccination is by drinking-water administration of turkey-spleen-propagated pheasant-origin live avirulent virus to 4 1/2-week-old-poults. The effect of vaccination was studied in a field location having recurrent 10-15% mortality and in a second location having recurrent mortality of 0.1-0.2%. The poults involved totaled 214,554.
