Vaccination for Hemorrhagic Enteritis of Turkeys

Abstract
Laboratory and field evidence indicates that a safe and effective procedure was 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-wk-old-poults. The effect of vaccination was studied in a field location having recurrent 10-15% mortlity and in a 2nd location having recurrent mortality of 0.1-0.2%. The poults involved totaled 214,554.
