Treatment of bovine sub-clinical mastitis with homeopathic remedies

Considering the positive results of homeopathic therapy of bovine mastitis, the presented study should evaluate the effects of two standardized homeopathic methods in sub-clinical mastitis using a prospective randomized double-blind placebo control study design. A number of 124 dairy cows from 17 herds with increased somatic cell count were selected and randomly associated to 5 treatment groups. Two groups received a peroral therapy with (a) a homeopathic combination over 5 days and (b) a single treatment with a homeopathic nosode (Tuberculinum). To each treatment group a placebo control group was established with the same treatment frequency. A fifth group served as an untreated control. The bacteriological cure rate after 4 and 8 weeks was 28% and the total cure rate additionally regarding a normalized somatic cell count was 14% and 18%, respectively. There was no significant effect by the remedies at all. The cow somatic cell count over three months after treatment showed no significant difference in the five groups. Standardized homeopathic combinations and Tuberculinum nosodes are not able to control subclinical mastitis during lactation. If other factors like age and microbial agent are responsible for the success of homeopathy or if more individualized protocols provide better results has to be answered in further investigations.
