Abstract

Pairs of adult mallards (Anas platyrhynchos) were fed a control diet or a diet containing 1, 2, 4 or 8 ppm selenium in the form of seleno-DL-methionine. Ducklings from these pairs were fed an untreated diet from hatching through 6 d of age, at which time their avoidance of a fright stimulus was tested. Selenium had no effect on the ducklings' response to the fright stimulus.
