Aims: this study sought to assess the reproductive performance of sows inseminated with sperm treated with homeopathic medicines. Materials and methods: the semen of 2 sexually mature boars age 18 months Pietrain and Duroc cross-bred with similar genetic and reproductive performance were chosen, as well as 125 sows. Sixteen samples of semen were collected and standardized through semen evaluation. Three homeopathic preparations and a placebo (control) were tested on the sperm (n=31/32 per group): Avena sativa 6cH, Pulsatilla nigricans 6cH and Avena sativa 6cH + Pulsatilla nigricans 6cH. Sows were inseminated 3 times with the same estrous diagnostic procedures. Results: there was significant difference (p<0.05) between Avena sativa 6cH and the other 3 groups regarding the return to estrus and parturition rate. There was no significant difference among the groups regarding the number of newborn piglets. Conclusion: these data suggest that homeopathic preparation Avena sativa may be used directly on sperm cells to improve the parturition rate in technified swine farms.
