The preliminary results on the application of herbal drugs in prevention and treatment of metritis in dairy cows

Abstract

The use of antibiotics as the first treatment choice for metritis in dairy cows leads to many significant consequences, such as the antibiotic resistance and residue of antibiotics in the milk products. In order to find out a new substance that can be substituted for antibiotics in prophylaxis and therapy of cow metritis, this study was conducted to investigate the effect of one drug made of herbal plants so as to serve for the above purpose (this herbal drug was in suspension solution form and was a product from one Viet Nam National Research Project, code: DTDL CN-52/15). The trial result showed that use of this drug with a dose of 1ml/20kg P (equal to 10mg/kg P), for pump and wash in intrauterine had given significant effects in the prevention, treatment of cow metritis. Firstly,this drug had reduced the total numbers of aerobic bacteria in the vaginal mucus discharging after delivery. In addition, the time of pink and white colour mucus discharge, as well as the total mucus discharge time were shorter, and the metritis rate of cows after delivery was lower. Application of herbal drugs also showed significant effects in the treatment of endometritis. One hundred percent of the affected cows was recovered from the disease, with an average treatment time was 5.20 ± 0.96 days, (equally the time of using antibiotics). In addition, reproductive ability of cows in treatment with herbal drugs was higher than those in treatment by antibiotics, such as after treatment by herbal drug, 72.00 % of cows were re-ruting, of which, 55.55 % of cows were pregnant after thefirst mating. Meanwhile, using antibiotic treatment had given only 64.00 % of re-ruting cows and 50.00 % of pregnant cows.
