| Abstract | ||||
| Endometritis affects many mares and results in reduced fertility and economic losses to the horse breeding industry. Mares that are susceptible to postmating endometritis have impaired uterine clearance resulting in accumulation of fluid and inflammatory products within the uterine lumen, The effect of clearing uterine fluid on the pregnancy rate was studied in 36 Thoroughbred mares. Mares were allocated to 4 treatments: 1) Untreated controls, 2) Intrauterine infusion of broad-spectrum antibiotics, 3) Oxytocin injection, and 4) Oxytocin injection followed by intrauterine infusion of antibiotics. Pregnancy rates of all treated groups were significantly higher than the untreated controls and it was accompanied by a significant decrease in intrauterine fluid accumulation monitored by ultrasonography. Pregnancy rate in mares treated with oxytocin and antibiotics was higher than that of groups 2 and 3. It appears that this combination treatment, which had two modes of action (antibacterial activity and fluid drainage) might assist in the clearance of intraluminal uterine fluid and in increasing pregnancy rate in mares susceptible to postmating endometritis. | ||||
