http://orgprints.org/14475/ Analyse der Fruchtbarkeit und ihrer Kontrolle in biologisch wirtschaftenden Milchviehbetrieben A retrospective study was performed including 54 Swiss dairy farms of an udder health extension project. The objective was to evaluate additional effects on fertility parameters in the first two project years (y1, y2) compared to the year before (y0). Of 1494 lactations 251 diagnoses associated to reproduction and obstetrics were performed (17 per 100 Lactations). Ovary disorders (29%), retentio secundinarum (25%) and metritis (20%) were the most common items. Ovary disorders could be treated by homeopathy as successful as by hormones. Uterine disorders (ret sec., metritis) were followed by significantly better fertility parameters (days to first insemination 60 vs. 84 days, calving conception interval 68 vs. 118 days) after homeopathic treatment compared to antibiosis. Fertility parameters have been significantly enhanced from y0 to y2. Homeopathic treatment proportion increased from 4% to approx. 30%. This indicates that an udder health programme can lead to improved fertility parameters and therapy concept conversion as well.
