摘　　要：测定了休产期高邮鸭、淮安鸭、开封鸭的输卵管膨大部、峡部、子宫部及肾脏、肝脏的碳酸酐酶(CA)活力。同种鸭不同部位比较,碳酸酐酶活力的大小顺序为:肾脏>肝脏>峡部>膨大部>子宫部;不同种鸭同一部位比较,高邮鸭的肾脏、子宫、膨大部CA活力均最大,峡部与肝脏CA活力介于两种普通鸭之间。麻鸭肝脏和肾脏维持着体内生理代谢和酸碱平衡,休产期CA活力比输卵管强;高邮鸭子宫部Ca和CO32-的沉积能力较强,其肾脏提供的NaHCO3可能成为形成双黄蛋蛋壳的另一个CO32-来源。In the paper, carbonic anhydrase （CA） activity of magnum, isthmus, uterus in the oviduct, liver and kidney of the three species of ducks （Anatis Domesticae Caro Varities： Gaoyou, huaian and kaifeng） were determined during resting period. Comparison among CA activities of all these parts in the same duck indicated that, the CA activity of kidney 〉 liver 〉 isthmus 〉 magnum 〉 uterus. Comparison among CA activities of the same parts in different ducks display that CA activity of kidney, magnum and uterus of Gaoyou duck are the highest; CA activities of isthmus and liver are between those of the other two ducks. CA activities of kidney and liver in sheldrakes were stronger than those of oviduct, contributing to keeping the normal physiological metabolism and acid-base balance. The sediment of Ca and CO32＂ from Gaoyou duck＇s uterus was stronger than the other two. NaHCO3 supplemented by Kidney of Gaoyou duck, would be an additional CO3^2- supply required for the formation of double-yolk eggshell.
