This experiment was conducted to investigate Pb concentrations in soft tissues and eggs from laying Tsaiya ducks (Anas platyrhynchos var. domestica), dosed via gelatin capsule with 10 or 20 mg Pb/kg BW daily for 3 mo. Body weights of ducks were not influenced by Pb treatment. In addition, no clinical syndromes involving Pb intoxication were found throughout the experiment. The two levels of Pb consistently resulted in increases in the Pb content of blood, kidney, liver, and gizzard, whereas only 20 mg Pb/kg BW per d of dose additionally increased the Pb in femoral muscle. More Pb was deposited in the kidney and liver after Pb exposure than in the gizzard or femoral muscle. Lead residues in yolk and eggshell from Pb-dosed ducks were significantly higher than in controls; however, Pb in albumen was generally low and was not influenced by Pb treatment.
本实验旨在研究通过明胶胶囊每日给产蛋的菜鸭（Anas platyrhynchos var. domestica）投喂10或20毫克/千克体重的铅，持续3个月后，鸭软组织和蛋中的铅浓度。鸭的体重不受铅处理的影响。此外，在整个实验过程中未发现涉及铅中毒的临床症状。两个铅水平均导致血液、肾脏、肝脏和砂囊中的铅含量增加，而仅每日每千克体重20毫克铅的剂量额外增加了股肌中的铅含量。铅暴露后，肾脏和肝脏中的铅沉积量高于砂囊或股肌。投喂铅的鸭所产蛋的蛋黄和蛋壳中的铅残留量显著高于对照组；然而，蛋白中的铅含量通常较低，且不受铅处理的影响。
