The incidence of subclinical endometritis in repeat breeding dairy cows and the comparative efficacy of different antibiotics and herbal intrauterine therapy

Abstract

The present research work was conducted to investigate the incidence of subclinical endometritis (SE) in repeat breeder dairy cattle, and to study the comparative efficacy of different antimicrobial and polyherbal intrauterine therapies. Repeat breeding crossbred cows (>90 days in milking) with clear cervico-vaginal mucous discharge in spontaneous estrus were examined for uterine cytology by the cytobrush technique. The cows with ≥ 4% polymorphonuclear cells (PMNs) in uterine cytology were considered to be affected with SE. These cows were randomly and equally divided (n=12/group) into 5 groups and treated with the intrauterine medicine Vodine-IU (T1), Metricare-IU (T2), Utriguard-IU (T3), Uraksha (polyherbal preparation) (T4), or left untreated (control/C). In the subsequent estrus, uterine cytology was repeated and the cows were inseminated. The cows that failed to conceive but showed estrus were re-inseminated. The pregnancy status was checked. The incidence of SE was observed to be 36.80% (60/163). The PMNs percentage significantly declined in all the treatment group cows in response to treatment. The highest conception rate was observed in the T4 group (Uraksha treated) cows. It was concluded that the uterine cytobrush technique can be used efficiently for diagnosis of SE in dairy cattle, and polyherbal intrauterine drugs may be a good alternative in intrauterine antimicrobial therapy.
