A first generation cephalosporin dry cow intramammary antibiotic has been launched by Zoetis.

CefshotCefshot, available in multiples of 24 and 120 tubes, can be used for treatment of subclinical mastitis at drying off, with action against Gram-positive and Gram-negative bacteria. This makes three-way selective dry cow therapy possible, according to vet Jude Roberts.

Dr Roberts said: “With evidence-based triage, this covers teat sealant solo, in combination with narrow spectrum cloxacillin, or now with broader spectrum long acting cephalonium.

“This is in keeping with the trend from milk buyers for increasing precision in the use of antibiotic dry cow therapy, and only when it is justified in the first place.”
