摘要
３８０日龄北京白鸡８０只被随机分成２个处理，每个处理４个重复，每个重复１０只鸡，对照组喂基础日粮，试验组在基础日粮中添加５０ｍｇ／ｋｇ杆菌肽锌．试验被安排在１９９８年６月３０日至７月３０日进行．试验结果表明：杆菌肽锌对产蛋鸡平均产蛋量、平均蛋重及饲料转化率没有显著影响，但却可以明显改善蛋壳质量（蛋壳强度、蛋壳厚度）（Ｐ＜０．０５），并显著减少破软蛋率（Ｐ＜０．０１）．而且在夏季（３２℃以上）蛋鸡产蛋率下降阶段可以减少产蛋率的下降幅度．杆菌肽锌对蛋鸡血液中Ｃａ、Ｐ、Ｚｎ及ＡＬＫＰ（碱性磷酸酶）含量的影响不显著．
A trial on adding zinc bacitracin was conducted.The results showed that znic bacitracin is not significantly effective on average egg production,average egg weight and feed conversionrate,but zinc bacitracin can significantly improve egg shell quality,reduce broken egg rate,and decrease fall degress of laying rate.znic bacitracin is not significantly effective on content of Ca,P,Zn,ALKP in plasma.\=
