Abstract: The aim of this experiment was to study the safety of cefquinome sulfate intrauterine infusion for lactating cows.24 healthy lactating Chinese Holstein cows were randomly divided into four groups(6 cows in each group).Cows in groups Ⅰ, Ⅱ and Ⅲ were respectively injected different doses of cefquinome sulfate intrauterine infusion in uterus, and cows in the blank control group(group Ⅳ) were injected the dose of sterilized saline water.The cows were injected with the tested drug in uterus for twice and the interval was 72 h.The indicators including body temperature(rectal temperature), pulse rate, respiratory rate, blood physiological and biochemical indexes, mental state, daily milk yield and somatic cell count(SCC) in milk were respectively observed and measured on the day of first administration, the day of final administration and the 7th day after final administration.The results showed that injecting lactating cows cefquinome sulfate intrauterine infusion to lactating cows as recommended dosage was safe.The drug could be used to treat endometritis of lactating cows in clinical practice.
