    Abstract : In two experiments, Zn-65 distribution was studied in several tissues of zinc-deficient and normal bull calves over periods of 56-70 days after single oral or i/v dosing. With some tissues, such as liver, Zn-65 level reached a peak within a very few days after either method of dosing. In others, including r.b.c., muscle, bone, and hair, a peak did not occur until several weeks after oral or i/v dosing. In both orally and i/v dosed animals, skin, testicle, scrotum, kidney, muscle, heart, lung and spleen from zinc-deficient animals contained a higher percentage of the total body burden than did comparable tissues of normal animals. Pancreas from controls contained more Zn-65. In all instances, bones of control animals contained much higher levels of Zn-65 than those from deficient ones. Rib and tuber coxae bones contained higher Zn-65 levels than did tibia.
