Ampicillin was given orally to five Holstein calves using the following four different methods of administration: via stomach tube, mixed and fed in the calf starter ration, dissolved in milk and pail fed and administered orally as 400 mg commercial calf tablets. In addition, ampicillin was dissolved in milk and pail fed 20 to 30 minutes following intramuscular atropine. Ampicillin was only detected in the plasma of calves which had received the drug, pail fed in milk. Atropine administration slowed the appearance of the drug in the plasma but did not decrease the efficiency of absorption.
通过胃管给药、混入犊牛开食料中喂食、溶解于牛奶中用桶喂服以及口服400毫克市售犊牛片剂。此外，在肌肉注射阿托品后20至30分钟，将氨苄西林溶解于牛奶中用桶喂服。仅在通过牛奶用桶喂服药物的犊牛血浆中检测到氨苄西林。阿托品的使用减缓了药物在血浆中的出现，但并未降低吸收效率。
