Summary

Experiments were conduct] to investigat Pb concentrations in eggs from laying lsaiya ducks (Anas platyrhynchc6 var. omestica) dcsed daily via gelatin capcule with different amount of Pb. Irs experiment 1, the doses of lead were erprivalent to 0,10, and 20 rag Ph/kg b3dy weight for 3 months. No clinical syndromes involving Pb intoxication was found throughout the experiment period. The two levels of Pb consisttly result] in increases inthe Pb content of blood. Lead residues in yolk and egg shell from lead-dosed ducks were significantly higher than from controls.
