Last night my friend had a power failure and her stud got into the mare's area where there happened to be a 10 month old filly. She doesn't know if the filly is cycling yet, and doesn't know if the stud could have covered her. Could she be cycling at 10 mos. and could she conceive? If so, what does she do to curtail the pregnancy? Is it best to treat it as a successful cover and abort 'it'? If so what & when? Bearing in mind the young age of the filly it has to be 100% safe...
Yes, it's possible that she could be in heat and she could concieve. To be on the safe side you could treat it as a successful cover. You could also take the filly back over to the stallion to see how she reacts and use that information to see what action you want to take.
Any filly from about 9 months of age onwards may be sexually mature. Typically in this type of situation one would give prostaglandin, but in this particular situation, as one is dealing with a smaller filly, one may want to consult the veterinarian for correct dosages before using a full dose. The prstaglandin needs to be given at least 6 days after an ovulation in order to be successful in causing an abortion, which could be difficult not knowing what is going on with the filly, but one could give 2 doses 1 days apart and be sure to cause pregnancy loss with one of them.
Great news, thanks Jos. Up to how many days post ovulation can the prostaglandin be given for it to guarantee pregnancy loss? i.e. what is the latest post ovulation one can give the prostaglandin? Thank You!
