| 摘 要： | 在基础日粮（含碘０．２００８ｍｇ／ｋｇ）中添加１２５０ｍｇ／ｋｇ碘，对Ｈｉｓｅｘ蛋鸡连续饲喂５周，使其卵巢皮质内初级卵泡的闭锁率较对照组升高差异极显著（Ｐ＜０．０１），次级卵泡的闭锁率上升差异显著（Ｐ＜０．０５），单位面积卵泡的最大密度下降差异极显著（Ｐ＜０．０１），卵巢基质内印黄颗粒的最大密度上升差异极显著（Ｐ＜０．０１），卵巢间质细胞最大密度升高差异显著（Ｐ＜０．０１）．试验提示，高碘引起鸡产蛋量下降的主要形态学基础是各级卵泡的闭锁．

| Abstract: | Excess dietary iodine was fed to Hisxe hens for 5 weeks and the atresia rate of primary follicles and secondary follicles increased significantly (P < 0. 01 or P < 0. 05 ). The maximum density of primary follicles decreased significantly(P<0. 01 ). The maximun density of yolk granuses in ovary ground substance increased significantly(P<0. 01 ). The maximum density of interstitial cell in ovary increased significantly (P < 0. 05 ). The date show that the morphological foundation of egg production decrased is atresia of ovarian follicles in different levels. |
