Cows without signs of clinical mastitis were evaluated by the California Mastitis Test at calving (Day 0). Milk samples from 117 of 184 quarters (64 cows) were positive by this test for mastitis and were submitted for bacterial culture and determination of somatic cell counts. Cows with infected quarters were randomly allocated to treatment with cephapirin sodium by intramammary infusion or to be untreated as controls. Two and 4 weeks following calving, milk was again sampled from the infected quarters and tested. By the 4-week evaluation, the quarters treated with cephapirin sodium had significantly (P < or = .05) fewer positive bacterial cultures and somatic cell counts were significantly (P < or =.05) reduced compared with untreated control quarters.
在产犊时（第0天），通过加利福尼亚乳房炎检测对无临床乳房炎症状的奶牛进行评估。184个乳腺区中的117个（64头奶牛）的牛奶样本经此检测呈乳房炎阳性，并被送去进行细菌培养和体细胞计数测定。感染乳腺区的奶牛被随机分配接受通过乳房内灌注头孢匹林钠治疗或不接受治疗作为对照。产犊后2周和4周，再次从感染的乳腺区采集牛奶样本并进行检测。到4周评估时，与未治疗的对照乳腺区相比，接受头孢匹林钠治疗的乳腺区细菌培养阳性显著减少（P≤0.05），体细胞计数也显著降低（P≤0.05）。
