[Experimental modification of the resorption process and lead deposition in the body of the domestic duck].

In an experiment with 40 domestic ducks (Peking White breed) being 40 days old, it was shown that the process of lead resorption and deposition was neither significantly modified by different kinds of therapy nor by changes of food composition. A single dose of 30 lead small shot given to the experimental animals resulted after 1 week in a significant increase of lead concentration in liver (4.32 mg/kg-1), kidney (11.

[Experimental control of the process of lead absorption and deposition in domestic ducks].

A trial was conducted with 40 domestic ducks of the White Pekin breed at the age of 40 days: thirty pieces of lead shot were introduced as a single dose in the gizzard. The process of lead resorption and deposition was found not to be significantly influenced by the therapeutic treatments nor changes in the composition of feed. A week after the administration of shot a significant increase was recorded in the content of lead to 4.
