ABSTRACT
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 (11.36 mg/kg-1) and muscle tissue (1.15 mg/kg-1) as compared to the values of control animals (liver 0.07, kidney 0.11 and muscle 0.06 mg Pb/kg-1). After 3 weeks with different types of therapy and feeding of experimental diets, i.e. at the end of the experiment, no significant differences in liver, kidney and muscle lead concentrations between the control and experimental animals could be found.

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 4.32 mg in liver, to 11.36 mg in kidney and to 1.15 mg in muscle (the respective values for the control animals were 0.07, 0.11 and 0.06 mg per kg). At the end of the trial after three weeks of treatment and administration of experimental diets, no significant differences were recorded in lead content in liver, kidney and muscle between the untreated and treated ducks nor ducks fed experimental diets.
