    EFFECTS OF HIGH DIETARY IODINE ON THE REPRODUCTIVE PERFORMANCE OF HENS

    • 摘要: 在25周龄母鸡日粮中添加高剂量碘化钾,持续16周,观察产蛋率,种蛋受精率及孵化率的变化,并用RIA法测定鸡血浆中的雌激素、孕酮浓度.结果表明,高碘组母鸡产蛋率下降,种蛋爱精率无明显变化但孵化率降低.母鸡血浆雌激素的基础分泌量无显著变化,但高碘引起孕酮基础分泌量升高,而且导致雌激素、孕酮的周期分泌率紊乱.

       

      Abstract: week laying hens were fed with high iodine diets for 16 weeks.Observations were made on egg production, fertility and hatchability.The concentrations of estrogen and progesterone in the plasma were measured by radioimmunoassay.Com pared to those in the control group.the egg production of hens fed high dietary io dine were obviously lower at the end of the experiment.No significantdifference was observed in fertility but hatchability decreased with the increasing dietary ioding.The basal lever of estrogen in plasma showed little changes while the basal progesterone level increased significantly,and the secretion of estrogen and progesterone during the ovulatory cycle showed abnormality with high dietary iodine.
