Uranium metabolism associated with ontogenetic growth of birds: case studies with broilers and ducks
(Scientific Research, 2014)
Cobb broilers and domestic ducks, both one-day-old, were treated using ration doped with 20 ppm of uranyl nitrate. Uranium concentrations in the tibia (μg-U/g-bone) were measured by neutron activation analysis as function ...
