We are currently dealing with a mare who is difficult to say the least.

As a maiden, she got in foal first cover and delivered a lovely colt...all text book. That's the end of her being easy.

She took about 3 months to cycle after foaling. We ignore foal heat, so can't even be certain if she had that. But lutalyse was used (there was evidence of a CL at one stage) with no effect. When she finally did cycle, she missed first cover and cycled normally next time, and got in foal that time.

At around 8 months she aborted and has had few cycles this year. She started really late and has had 3 covers...with oxytocin following the last 2. We changed stallions for the last cover, but only because the one she was going to is old and finding cover very difficult. We'll know if she took this time in a couple of days, but I must say, I'm not confident.

The thing that I'm curious about is thyroid. I've read a bit about it here, but never seen a mare with a problem. All the usual things have been ruled out with this mare and I wonder if anyone could tell me what to look for. We are considering a blood test, but I'd like to know as much as possible about this and any other, less obvious things to look for.

Lisa,

I can't be of great help here, but I can tell you this... My mare was discovered to have VERY low thyroid levels and I had no indication except she was a fairly easy keeper. I too had problems with her. She came also came into season very late this spring, and was bred consistantly and correctly by AI, but never took. I'm no expert on low thyroid, but I really didn't notice anything that would have led me to believe she was low thyroid except she wouldn't settle. I'd get the blood test done. Good Luck.

Thanks Jennifer! This mare only has to sniff food to put weight on.

We had her preg tested today...she's still empty, and will now stay that way until next year as her boyfriend has moved to the USA for the next 6 months or so.
I'll talk to the owner and see if I can convince him to do the test. She's such a good mare in every other way.

Lisa and Jennifer,
I also have a mare I have been trying to get bred and she did not take all season in 2005 from March to October! I am crushed as she is a special horse to me and my family and I would love for her to have a baby for us. She also only needs to sniff food to gain weight and has had four foals in the past and was an excellent mother. Is there a treatment for the thyroid problem or should I just move on and enjoy her as a nice riding mare?
Thanks,
Heather

Treatment...ABSOLUTLY! I am using Thyro-L to treat my mare, and I know others who have had success using it. My vet is confident she will take this year as she is sound in every other department. If she has had other foals in the past, you might want to consider a breeding soundness exam. From what I understand, the more babies they have, the harder it is to concieve/carry-to-term due to uterine damage from foaling. This may or may not be your case, so a simple thyroid test is a good start for this coming season. I will keep my fingers crossed for you.

PS Thyro-L is cheap I think it is around 19.00 USD for a one lb supply. Not sure how long it will last you, depends on the dose they put her on, and we started late December. My mare has shown improvement in the attitude dept, and lost some weight. I am hopeful that the next pull will be in the normal range! We are looking for a 20 to a 22...she was a 9

Well, the owner has asked for the test, but the vet wasn't too happy about it. He basically told me it was rare enough not to bother, but took the blood anyway, as the owner requested it.

Is there a link to any good articles on this? I feel if I could show him something about this, he may look into it a little more for future reference.

Looking back, we have had a few really fat mares that just would not take and we just put it down to the age old thing of fat mares not being as fertile. Maybe that's because their thyroid function was dodgy?

I had problems with my 22 year old mare settling also. I had the T4 test done in late April and it came back a 9 - right in the middle of normal. Bred her on May 22, u/s in foal June 10 - or what we thought was the foal - and also was put on Regumate May 28 - older mare and had lost 2004 foal. By July we decided what we were seeing on the u/s was not a foal and stopped regumate. I had read all the posts concerning thyroid problems on the equine repro site and decided to try the Thyro-L. My vet was very skeptical but did get me in a jar of it. My mare cycled twice and settled on the 2nd time. U/s at 90 days and foal is still there!!! My vet is not skeptical anymore.
I have asked why there has not been a study done of thyroid problems on hard to get in foal mares and the answer is that no one mare is the same as far as why the low thyroid. So..........anyway I will continue to use the Thyro-L and have babies out of this mare. She is foundation bred very well and I just love her 2 year old colt that I have and want a filly now!!

I was just searching for info about this and found this site.
http://www.veterinarypartner.com/Content.plx?P=A&C=189&A=1931&S=0

It is a little scary! Particularly about what happens if you supplement a mare who doesn't need it.

Cindy,

I am wondering about a score of 9 on the thyroid test. My vet thought this was VERY low, but yours said it was in the middle of normal. Have any info on the scoring levels. Maybe Jos could answer this one??

The best way for me to address this is to point you at BET Labs web site in Kentucky. Click on the logo with the US flag on it that is at the left, and then on the next page, click on "Equine" that appears in the flag-bearing logo at the top of the page. Then in the next page, click on "Equine T4 Normals" in the menu on the left. Sorry to be so convoluted, but it's a "frames" site, so it's difficult to send you to the page directly without losing the benefits of other links on the site. The chart you finally reach shows the normal ranges for various categories of animals.

Are the parameters the same in the US as for Australia....coz our mare is 10.3 and the norm acoording to that site is 12-30 for an open mare.

The vet hasn't got back to us on this but I was told the norm for a horse was between 10 and 28.

I'm soooo confused...

The other question I have is ...would supplementing her with kelp (for iodine) help?

Is there a site available that can give you some indication of some of the outward symptoms of either low T4 levels or high T4 levels?
