title: Chick edema disease syndrome in young turkey poults.
abstract: Two feeding bioassays were conducted to study the mortality pattern, incidence of edema and ascites formation and plasma composition of turkey poults fed diets containing varying levels of toxic fat (fat contaminated with polychlorinated dibenzo-p-dioxins) and/or salt. No significant changes in plasma concentrations of electrolyte and total protein and packed cell volume were observed in slaughtered poults fed diets containing toxic fat compared with poults fed a normal diet. However, a positive dose-response relationship between levels of dietary toxic fat (0,2 and 5%) and incidence of mortality with edema, ascites and hydropericardium was observed in poults fed diets containing 1% salt. The toxic effects of polychlorinated dibenzo-p-dioxins were accentuated by increasing the level of salt (0.5, 1 and 3%) in the diet. Mortality started at nine days of age and increased on days 10 and 11. The present experiments demonstrated that gross pathological changes similar to those reported for "chick edema disease" caused by feeding polychlorinated dibenzo-p-dioxins, could also be produced in young turkey poults. The etiology of the toxic effects of these organic compounds in edema formation is discussed.
