Streptococcus agalactiae (S. agalactiae) continues to be one of the major causes of subclinical mastitis in dairy cows and a considerable source of economic loss for the industry, including Iranian dairy herds. High mammary tissue and milk concentrations of ceftiofur following intramammary administration have been previously demonstrated. The objective of this study was to determine the effect of ceftiofur sodium as a therapeutic for blitz treatment of S. agalactiae on bulk tank somatic cell count (BTSCC) and milk yield of infected cattle in a large dairy herd in Iran.
