I think for the most part, it is a wonderful idea! I do have a couple of comments though, one in regards to what you wrote, and one in regards to what Keri wrote. Yours first...
I was thinking about a rule change by both registries that would allow horses to retain the papers they have, but not be allowed into the breeding pool. It would require a box on the papers where the breeder could check “ Not For Breeding” and would not be revocable by anyone except the original breeder.
Overall, I feel it will not solve all the problems, yet it will definitely help to keep the quality of our breed up, as well as allow people to own and show a horse that may for one reason or another not be suitable for breeding.
For Halter classes, they should not be allowed to participate in the regular halter classes, as those are to showcase the best of the best, and to use those superior models to breed our future. Since these horses we are referring to will be non-breeding, that would not apply to them, but I feel they SHOULD have some sort of a non-breeding Halter Class, as well as being able to participate openly in any and all performance classes.
I have colored in red, the part that may need rewording/rethinking. This mentions the breeder checking the box. I personally feel that little box option should be made available on every new registration application as well as every transfer! As an example as to why...
I bought a mare...6 year old maiden, pretty little mare. She was R only, I hardshipped her into A also. I bred her and she lost the foal late term....had to be cut out of her...pretty gruesome to say the least! Next time I bred her, she went into labor, the foal was breach. The vet and I were able to get that foal pulled breach position. That was all I wanted...I could no longer go through that with her.
I had no idea if this was just fluke or what, so I decided to sell her. When I did, I disclosed all info to anyone inquiring on her, and did not sell her as breeding sound...sold her with no guarantees. The lady that bought her took her chances, and she lost that foal too. That lady then also decided to sell her also being honest and informing the person as to why she was selling her as a pet only, WITHOUT papers and not to be used for breeding.
Now, IF this type of rule were implemented, in my example above, I would have liked to have been able to put that little check mark in that box when I sold her, and I know the other person would have like to have also been able to once she sold her. So, I guess what I am saying is, that I feel not only the breeder should have the right, but anyone owning the horse along the way should also have that right, and NO ONE other than the actual person that placed the restriction should be able to lift it, not even the breeder, if it was someone other than them that placed the restriction. Furthermore, even then, both the owner and person owning the horse at the time would BOTH have to apply and sign for it together. That way when a person places this restriction, there is always a reason they have done so, and no one can overturn that decision.
This brings me to my next comment, directed towards Keri's comment. My example above should hopefully help explain to you the reason(s) why someone may place this restriction. It doesn't always mean the horse is not quality, it just means that for whatever the reason, the breeder or the owner thereafter that places the restriction is doing so for a reason that THEY are firmly set about. So it may be a World Champion, and could still be set with these papers at some point. Some breeders may want to do it as their way of trying to reduce overpopulation...no, it won't guarantee the horse won;t be bred, BUT, it will guarantee that no offspring from that horse will be allowed registration! Many people will sell a quality horse for a pet price to a good home, or a show home, or a 4H home etc. Just because there are breeding restrictions placed, does not automatically make them an unworthy specimen of the breed. Yes, some will be poor examples for one reason or another, but not all will. And as to you r comment about everyone seeing the quality differently, like if I say it is not breeding quality, but you think it is, if it is my horse that I am selling, and I feel that is something I want as a condition of the sale, that is what I will do. You, as the potential buyer has 2 options...agree to the condition, buy the horse and have fun with it and love it regardless, or walk away, and buy a breeding horse from another farm. (or another from my farm if you want, but all I am saying is it is your choice to buy that horse with the restriction, or not.)
By the way, I find a forum such as this such a useful tool in coming up with new rules. When brought before so many people in this way, they have plenty of time to think, and come up with ideas on what or might not fly, and why.
Thanks for asking this here, we sure need to see more of this in the future to get an idea of the general memberships reactions to such rule additions/changes. What one person may overlook, another may catch, and this too may help to get things through the proper channels sooner.
