Abstract: The aim of the experiment was to research the safety of cefquinome sulfate intramammary infusion for lactating cows.12 healthy lactating cows (6 were primiparous and 6 were multiparous) were selected to inject 1 peice of cefquinome sulfate intramammary infusion (dose:8 g:75 mg/piece) into four dairy regions of each cow for 3 times,and its interval of the administration was 12 h,and the evaluation indicators included the differences of clinical manifestation grade,daily yielding,somatic cells number and the changes of pathogen in dairy regions in milk before and after administration.The results showed that there were no significant differences in indicators all above before or after the treatment (P>0.05),which suggested that cefquinome sulfate intramammary infusion was safe to lactating cows when administrated according to the dosing regimen above.
