In the cow, retention of the fetal membranes for more than six to eight hours post-partum is one of the commonest diseases in the postpartum period [1] . It can lead not only to the persistence of putrefying tissue but also to reduced milk yield, an increased incidence and severity of endometritis and poorer fertility [2]. Treatment should therefore be aimed at reducing these effects and removing the retained placenta (RP). The therapy of RP has been a controversial subject for many years. Manual removal of fetal membranes and an intra-uterine antibiotic treatment are common in veterinary practice. The aim of this study were use smoke of Peganum harmala L seeds and Donkey excrement on retain placenta in dairy cattle. Two dairy cattle were used in this study. In first cow was used mixed smoke of Peganum harmala L seeds and Donkey excrement and second cow was used smoke of Peganum harmala L seeds. Results showed that retained placenta in two dairy cattle were improved. In this work, the medicinal smokes containing effective ingredients could prevent the growth of infection and may be used as an available source for medicinal purposes.
