Abstract

Oxytocin was administered to reduce incidence of retained placenta and uterine infections that could delay subsequent conception. Three hundred and fifty multiparous Friesian cows, each with spontaneous delivery of a single calf were divided randomly into two groups. Some (n = 175) were injected with 30 IU of oxytocin immediately after delivery and again 2-4 h later, while the remainder formed an untreated control group. The placental retention 24 h after parturition was 24.6% and 10.9% in control and treated animals respectively (P < 0.01). Endometritis occurred in 5 1.6% of the animals following placental retention as compared to 10.4% of those with normal expulsion of the fetal membranes (P < 0.001). A comparison of reproductive indices showed a statistically significant improvement of fertility in treated cows with the average interval from calving to conception being reduced from 124.4 d to 93.7 d (P < 0.0001).
