    Default Older mare, frozen or fresh?

    My mare had her first foal at the age of 17 and went straight back in foal. She's expecting her second foal next year. Both were conceived with fresh, chilled semen that is very good quality (Silvermoon). After being inseminated the first time she had significant fluid retention issues but the vets were amazing and cleared it all after a week of intensive work. Second time round there were no problems at all and no fluid. Her next baby is due in May.

    She will be 18 years old in 2011 and I was wondering whether anyone has used frozen successfully on an older mare? Or should I stick to fresh chilled semen as I know that works for her?

    Yes, we used frozen on a 20 year old mare (who had a foal afoot) who settled on the first insemination. At age 21 we also used frozen -- same thing. Settled immediately. The fact that your mare, at her age, has remained reproductively active is good.

    Default older mare...frozen or fresh?

    It is always a recommendation as opposed to a rule, that mares in their upper teens and older do better with fresh chilled. I have gotten conceptions out of mares into their 20s with frozen, but their are some rules. Of course the semen must be of excellent quality and sufficient amount of progressively motile cells. Since frozen creates more of a uterin inflamatory response, it would be a good idea if your vets were on top of it prior. It sounds like they are, from your previous experience. Flushes pre and post, plus oxytocin and banamine will undoubtably increase your chances. Best of luck,

    This year I bred my 19-year old broodmare with frozen. Her previous 6 foals were all conceived with fresh chilled. Her last two conceptions with fresh chilled were a bit difficult due to cysts and cycling irregularities, so I was a bit hesitant to use frozen this year, but I it was a breeding I wanted to do with this mare before I retired her from breeding permanently, so I took the chance and she took on her first cycle after the foal heat. Good luck!

    My granny-mare (20) was open for years with her previous owner, I bred her with fresh first, she foaled then caught with a single dose of frozen for '11. She is healthy, has a bloom to her and I was told her dam was bred with no complications until 23. I think its harder, but if its a great cross I would give it at least one shot. and on Facebook too!

    I bred my 19-year-old maiden mare with frozen. Used half-a-dose that had gotten other mares pregnant. No luck. Second round -- used a dose-and-a-half. Success! Three embryos, flushed and implanted in recipients and....three healthy foals who come this Jan. 1, will be two years old. (I believe the vet inseminated very high in the horn.)

    Thankyou everyone for your feedback. It is encouraging to hear so many older mares getting pregnant from frozen semen. I'm going to have to think long and hard about what to do next year!
