肉?飼料中分別添加2%～5%國產天然沸石粉及 50ppm 金黴素，經3～6
週再以大腸桿菌及雛白痢菌分別經口感染??，觀察其預防效果，並與不添加組作
比較。
三種添加飼料之??對大腸桿菌及雛白痢菌感染之發病率較不添加之對照組極
顯著的減少（p＜0.005），而且以添加5%然沸石粉者最優，其次為添加2%者
。此證明國產天然沸石粉可以代替金黴素等抗生素添加劑以防治?大腸桿菌及雛白
痢菌引起之下痢症。
在肉?之體重增加方面，飼料中添加2%國產天然沸石粉（Zeolite）在生長後
期較5%者為佳，故肉?之飼料中添加國產天然沸石粉之量以2%者較適宜。在試
管中，9 ml 之大腸桿菌（5.6 x /ml）或雛白痢菌（4.2 x ）加 1gm 國產
天然沸石粉，於6小時內可將該細菌完全吸附，此說明國產天然沸石粉對大腸桿菌
及雛白痢菌之吸附作用。 - 英文摘要： Broiler were fed with 2%, 5% ofnative zeolite and 50 ppm aureomycin,respectively, On 21th, 31th and 41thdays old, these chickens were experi-mentely infected with E. coli and Sal.pullorum by drinking water. The mor-bidity of chicken with zeolite or aureo-mycin was significantly lower than thatof control chicken, the most effectiveration is chicken with 5% of zeolite.The result demonstrated that nativezeolite could be considered as a feedsupplement in replace of antibiotics forprophylasis of fowl bacterial diarrhea. The average body weight gain oflate growing period (5-8th wks old) ofbroiler with 2% zeolite is better thanthat of broiler with 5%, it seems 2%zeolite is the more suitable ration. Invitro, 9 ml of 5.6 x E. coli or Sal.pullorum mixed with 1 gm of nativezeolite, all bacteria were absorbedwithin 6 hrs. This result demonstratedthat the native zeolite has strong poweron absorption of E. coli and Sal.pullorum.
