Hi Im concidering breeding from my mare next year. She has had a good run jumping up to 1.30, she is coming up for 11yrs and the intention was to always have a foal from her as I bred her. Also I would like to concentrate on my 5yr old.

She is very very quite about coming into season - in fact I never notice, it would be very hard timing insemination, in addion as she can be very twitchy about her back legs a few studs have suggested a hormone injection, rather than a possible "flirting" with one of their stallions.

Can anyone tell me about this injection, what it involves, when is it done, when would she be inseminated and any side effects/risks?

Thanks
 
I'm not the one most qualified on here to answer this as I consider myself a very amateur breeder but ive bred a few foals and experienced the very same thing. I found that keeping a good record of teasing and how your mare reacts at various times in her cycle is really helpful for future reference and costs nothing. You might think she doesn't show in season but you may well notice some slight changes to give you clues.

Your vet can scan her to tell you where she's up to in her cycle and can give her an injection of Progesterone (PG) to bring her in. It can only be done at certain times but lots of people get their mares in season this way as it saves time by shortening the cycle. My mare came into season 5 days after her PG jab and was covered 2 days later and has subsequently been scanned in foal. Side-effects wise, my vet warned me that she would probably sweat profusely and i'm glad he mentioned that because she really was wet through about 20mins after.

Good luck with it all :)

prostaglandin not progesterone.
Progesterone is regumate

Basically, your vet scans for stage of cycle (and it DOES need to be a vet experienced in repro work as your average vet is totally useless at scanning mares!!:rolleyes:) Then, assuming she's mid-cycle, has a Corpus Luteum AND a follicle of at least 25mm, she has a shot of prostaglandin to bring her in. About 4 days later she needs to be scanned again, to determine if she has a decent follicle and IS coming in - and then maybe once more before ordering semen (and the scanning has to be done first thing in the morning as stallion owners like semen orders in no later than 11 am!) The vet may give her a shot of Chorulon to encourage her to ovulate 24-36 hours later - unless the follicle is VERY ripe!

Next morning, semen arrives (we get it sent to the vet as he checks it and then brings it straight out to AI.) He scans the mare again to be sure she hasn't already ovulated - and does the insemination. Because she's an 'old' maiden (anything over about 6 that hasn't foaled is an 'old' maiden :D ), he should recommend that the mare at LEAST has a shot of Oxytocin 6-8 hours later to help clear fluid, or that she is washed out - 6-8 hours later is ideal - or next morning at the latest.

As you can see, this involves a lot of vet visits - and for that reason it may be wise to send her to a GOOD stud to be AI'd. Although a GOOD stud will manage a mare who is 'twitchy' about her back legs safely for natural cover - it just requires plenty of teasing (over a solid wall) to make sure the mare is totally receptive, the use of felt kicking boots on the mare's back feet (to minimise risk of kicking doing damage) and good handling!
 
Im deffo no expert and send my girl to the stud for the duration, I kept a diary of when she was scanned, etc so I can create a story hopefully at the end of it all - not sure of its of any use to you? p.s my vet gave me 10 days worth of regumate to give her before she went to stud... complete waste of time :mad:
