Estimation of plasma thyroxine concentration in ducks in relation to different environmental and experimental
Experientia
|September 15, 1978
Abstract:
Plasma thyroxine concentration was measured in ducks by the thyroxine-binding globulin technique. The assay allowed us to detect annual variations in thyroid activity as well as significant changes after starvation or cold exposure. No detectable thyroxine was formed in surgically thyroidectomized ducks.
