近日，有讀者致電本報“牧醫110”反映，他家的蛋雞最近產白殼蛋，不知是什麼原因引起的。

臨床上較常見的蛋雞產白殼蛋的原因有：(1)遺傳因素。蛋雞可能本身是白殼蛋雞品種，白殼蛋雞品種有京白904、京白823、京白938、濱白42、濱白584、星雜288、海賽克斯白、巴布可克B-300、尼克白雞


、羅曼白、海蘭W-36、迪卡白等。(2)疾病因素引起雞蛋病理性發白。如蛋雞發生傳染性喉氣管炎
、非典型新城疫、減蛋綜合征
、傳染性支氣管炎等。(3)飼料中鈣等礦物質元素以及維生素等缺乏引起。一般在蛋雞開產前2周就應該在飼料中添加貝殼粉、石粉等。(4)應激因素引起。如剛剛轉群
、受到驚嚇、突然變更飼料等均可能會導致蛋雞暫時性產白殼蛋的現象，應激因素消除後雞群將恢複健康。(5)mujilaolinghua。yangzhishijianguochangdemujiyouyuzigongneisesuchenjijiaoshao
