Breeding update

Gina went to the vet for a pregnancy check on Wednesday, and I’m pleased to report she is in foal to Mannhattan! There were actually two embryos in there, which is somewhat common in Thoroughbred mares. Twin pregnancies in equines are bad all around, so my vet pinched off the slightly smaller embryo. (My neighbor joked that we should have done an embryo transfer to one of her mares.)

Is Gina cooking a mini-Gina in there?

My vet also recommended that Gina receive Regu-Mate to support her pregnancy. Regu-Mate is a synthetic progestagen which is most often used to suppress estrus; however, it’s sometimes recommended to help mares with low progesterone levels maintain pregnancies. (My vet recommended it due to Gina’s embryo absorption last year.) If you’re interested, Equine Reproduction has a thoughtful article on the subject.

Like last year, my vet recommended that Gina continue her usual diet and exercise regime. She advised that I’d probably want to stop riding her around month eight of pregnancy, but until then, it’s in Gina’s best interests to stay in good shape. I’m sure all the lesson students she regularly terrorizes are thrilled.

I’m just as excited about this cross as I was last year. I’ll even grudgingly accept a gray colt if it jumps like its sire!

    1. Yeah, my vet was like “would you rather do the once a month injectable or the daily oral?” and I was like “uh, let’s do the injectable, because the less I have to touch it, the better”

  1. Congrats! Here’s to a healthy pregnancy and foal! Thank

    Is the injectable still regumate? I’m going to have to ask about that for Annie.

    1. It’s the same thing, but the concentration doesn’t end up getting distributed as evenly. With the oral version the mare is getting a certain amount per day, every day. Very steady, easily controlled hormone levels. With the injectable, she gets a spike when the shot is first administered, then less and less is in her system as the duration between injections pass. So usually for pregnant mares that are “high risk”, the safest bet is giving it orally since it’s more consistent day to day. From what I’ve been told by Repro specialist vets, the injectable seems more common for use in showing mares that need hormone therapy. It works well for some, but not as well for others. So might be worth trying for Annie?

  2. Oh! I didn’t realize it is manhattan that she is bred to! He is one of my favorite stallions. Another blog I follow just bought a manhattan baby too!
