Abstract

1. Blood samples were collected from mallard ducks after 6, 12, and 18 weeks of dietary exposure to mash containing 0.015%, 0.150%, and 1.500% crude oil. 2. Plasma corticosterone concentrations in ducks fed mash containing 0.150% or 1.500% Alaskan Prudhoe Bay crude oil were uniformly depressed when compared to values in untreated control birds. 3. Plasma thyroxine concentration was not altered in ducks chronically exposed to crude oil. 4. The observed alteration in corticosterone concentration could reduce tolerance to temperature and dietary fluctuations in the environment.
