British Cattle Veterinary Association

Data were collated for an independent scientific analysis from a number of international, multi-centre studies that had compared the efficacy of three different, cephalosporin containing, intramammary preparations in the treatment of clinical mastitis in dairy cattle (Cefalexin in combination with Kanamycin (Group 1); Cefquinome (Group 2); Cefoperazone (Group 3)). Quarters were assessed using standard bacteriological techniques before treatment and at 16 and 25 days post treatment. Additional data were also available on individual cows and study farms including parity, breed and cow somatic cell count histories, herd bulk milk somatic cell counts (BMSCC) and farm management regimes.
