In a research institute numerous cases of amyloidosis were observed in 12 of 70 white Peking ducks kept in cages with wire bottoms. All 12 ducks also suffered from chronic inflammed alterations in the sole of foot zone (bumble-foot). A second flock of 40 white Peking ducks supplied with equivalent feed but kept outdoors showed neither signs of bumble foot nor amyloidosis. Likewise, after the healing of the bumble feet per adjustment of the wire bottoms (installing a wider footing area) no new cases of amyloidosis were noticed among the ducks kept in cages. Histologically deposits of amyloid were found in the liver, which was highly affected, the kidney, spleen, stomach, small and large intestines as well as pancreas. The fact that amyloidosis only appeared under certain circumstances indicates the presence of a secondary form of this illness.
在一家研究机构中，70只饲养在带金属网底笼子里的北京白鸭中有12只出现了大量淀粉样变病例。所有12只鸭子的足底区域也都患有慢性炎症性病变（蹼足炎）。另一群40只北京白鸭，喂食相同的饲料，但饲养在户外，既没有蹼足炎的迹象，也没有淀粉样变。同样，在调整金属网底（安装更宽的立足区域）使蹼足愈合后，饲养在笼子里的鸭子中没有发现新的淀粉样变病例。组织学检查发现，肝脏（受影响严重）、肾脏、脾脏、胃、小肠和大肠以及胰腺中都有淀粉样沉积物。淀粉样变仅在某些特定情况下出现，这一事实表明存在这种疾病的继发性形式。
