Embryo transfer

If this has been brought up already I'm sorry. Its just breeding season is upon us and it got me thinking when I received a email ad on buying an embryo.



What do you think of the embryo transfer that's gaining popularity? Will it give more chances of great foals or will it narrow down the genetic gene pool. Also, will it increase chances of poor horses by taking out nature? We already breed poorer horses with the advent of drugs and other treatments that get mares that can't breed naturally pregnant. Now you could breed mares that can't get pregnant at all.

What do you pass onto the foal then?
Will horses end up like the bulldogs that can only be bred AI and birthed by cesarean?


I'm on the fence myself... just curious as to what other horse breeders think?

With the cost it will really only geain popularity with higher end horses. The cost still averages about $5K.

I see it in reality widening the gene pool. Think if it this way. You are getting more foals out of great mares by different stallions so you are getting much more in the way of crosses that adds to the gene pool.

Also, will it increase chances of poor horses by taking out nature?

Not sure where you get this. With the cost of ETs only the best of the best are going to be using it. So you are not going to use ET for a $500 foal.

We already breed poorer horses with the advent of drugs and other treatments that get mares that can't breed naturally pregnant. Now you could breed mares that can't get pregnant at all.

Again not sure where you are getting this. With the advance of drugs and other artificial breeding you are actually getting more of the better end horses. Just think if Poco Lena was a live to today? Just think of having more then just Doc O'Lena and Dry Doc. Again how hard are you going to try and how much money are BYB going to spend on a $500 foal? Vs. What a top breeder will pay for a World Class foal.

What do you pass onto the foal then?
Will horses end up like the bulldogs that can only be bred AI and birthed by cesarean?
Again not sure where you are getting this. What it takes to get a ET on the ground you are only going to use the best. The recyp mare still has to foal out. Nothing changes but the fact that the doner mare is not carrying the foal.

I'm on the fence myself... just curious as to what other horse breeders think?

At the end of the day it give people a chance to own a foal out of a great mare. I have Embryos for sale from time to time. The cost of what I chage for the Embryo and the stud fees and shipping fees if you use a good stallion is less then what you would pay if I bred the mare myself. So at the end of the day makes a foal out of a great mare more affordable.

How so? A stallion can literally breed 100's of mares a year. With a mare, even with the use of ET, you can at a maximize and get if you do EVERYTHING correctly, maybe 8 to 10 foals a year.

ET is typically used on those mares that have proven themselves to be exceptional athletes themselves. Consequently, it is typically used on mares that are older with a successful performance record behind them. Older mares are not the best candidates for breeding for obvious reasons. Yes, you will always have people that will attempt to perpetuate a mare that is unable to carry a foal herself due to reproductive issues, but generally speaking, chances are the mares that are used for ET's are out there performing and the owners don't wish to stop their performance career, have ALREADY performed and are just too old to be breeding, or are too valuable to risk having them carry a foal of their own. With regards to reproductive issues, well, that comes down to people breeding responsibly. That will always be an issue regardless of the method of impregnantion and/or carrying the foal to term. Personally, we won't breed mares that have reproductive issues that can be passed on genetically AND we have the ability to do our own ET.s

The exact same genetic material that you would pass on to the foal that was carried by the donor animal.

You're not comparing apples to apples.

Personally, I have absolutely no issue with using ET as an attempt to get more foals out of a good producing mare. Obviously if the mare has genetic issues that prevent her from carrying a foal, she shouldn't be bred. And, if I can a few extra foals out of a superior mare, definitely well worth doing. Her impact on the gene pool is going to be minimal in the grand scheme of things. A stallion has the potential to impact things much more than a mare, for better or for worse.
