The best advise I got when I decided to breed my AQHA registered mare was to breed to better stallion than what my mare has as far as conformation for the most part. My mare's first born was by a TB stallion, her second and third born were by a AQHA Cutting bred Stallion.
Your mare's foal would be a keeper in your eyes, because you love, understandably, your mare and that would pass on the her foal. However, in the event something unexpected happened to you or your ablility to keep all your horses which one or ones could/would you keep? I am not trying to change your mind about breeding your mare. Just some "food" for thought.
I had a filly in 08 who my full intention from the day we bred my mare was to sell her so I chose the stud with the best confo & bloodlines.
The following year I bred to my favorite stud on the farm for an 09 baby as I intended to possibly keep the foal. She was exactly what I wanted looks & temperment wise, however that year feed was pretty sparse & very expenise so I gave the foal to my friend. I didn't sell her because I still wanted to be able to see her & watch her progress & my friend has yet to sell a horse lol so I know she'll be there forever.
I don't intend to breed until, as I said, this summer or next when I know the fencing will be complete and therefor i'll have more room for another horse. Right now we only have the one pasture fenced off & are feeding all year round
In my area, i've found that many people are like me in the sense that they couldn't care less about bloodlines, so long as the horse is sensible & handsome/pretty. This is why I am looking for a stud that will offer these attributes.
