摘　　要：以400日龄产紫皮蛋的农大3号节粮小型蛋鸡(试验组)、产紫皮蛋的普通褐壳蛋鸡(试验组)与普通的农大3号节粮小型褐壳蛋鸡(对照组)、普通褐壳蛋鸡(对照组)及白来航鸡为研究对象,对其蛋品质及孵化率进行比较。结果表明:同品系的普通紫皮蛋的蛋壳厚度比普通褐壳蛋的厚度高,差异达到极显著水平;同品系的普通紫皮蛋的哈氏单位比普通褐壳蛋的哈氏单位高,差异达显著水平;同品系矮小鸡的紫皮蛋的蛋壳色泽、蛋壳强度、蛋壳厚度及蛋黄色泽与普通褐壳蛋的差异达到极显著;紫皮蛋的蛋白高度与普通褐壳蛋的差异达到显著水平。随着保存时间的延长,紫皮蛋的孵化率高于普通蛋的孵化率。The egg quality and hatching rate between the dwarf with purple-shell egg and the normal purple-shell egg （test） and the nor- mal dwarf chicken and the normal brown-shell egg chicken （control） and also the White Leghorn at the age of 400 days was compared. Purple-shell egg line showed significantly thicker egg shell than normal brown-shell egg line （P〈0.01）. Purple-shell egg line showed significantly higher haugh unit than normal brown-shell egg line （P〈0.05）. The egg shell shade, intensity of eggshell, thickness of egg- shell and the shade of yolk also showed significantly different between the purple-shell egg and normal egg shell groups （P〈0.01）. Purple-shell egg line showed significantly larger albumen height than normal brown-shell egg line （P〈0.05）. The purple-shell egg bad higher hatching rate than the normal egg with the increase of the storage time.
