[Treatment and gestation results of mares with secondary retention].

The research article explores the effectiveness of intravenous oxytocine infusion in treating mares with retained fetal membranes, and observes the subsequent pregnancy outcomes. Results indicated a high success rate in both treatments and subsequent pregnancies.

Objectives of the Research

• The research aimed to investigate the effect of an oxytocin infusion on mares suffering from secondary retention of fetal membranes. Secondary retention occurs when parts of the placenta remain in the mare after foaling, which can lead to serious infections.
• The study also intended to evaluate reproductive performance of these mares following the applied treatment in the same breeding season.

Methodology

• A total of 29 mares diagnosed with secondary retention of fetal membranes were included in the study.
• The mares were treated with an intravenous infusion of oxytocin, a hormone that causes muscle contractions in the uterus and ejection of the placenta.
• The placenta release was monitored over a duration of two hours post infusion.
• The breeding success of these mares was then tracked in the same season of undergoing the treatment.

Results

• Following the oxytocin infusion, 83% of the mares (24 out of 29) released the retained placenta within two hours.
• Of these, 90% (26 out of 29) mares successfully became pregnant within the same breeding season.

Conclusions

• The study concluded that intravenous oxytocin infusion is an effective method for treating mares with secondary retention of fetal membranes, demonstrating a high success rate in terms of placenta release.
• Moreover, the study demonstrated that mares treated with oxytocin for retention of fetal membranes can successfully conceive within the same breeding season, indicating minimal interference with their reproductive health.
