OK this question is not about the debate on breeding but about weather half breed registries are worth registering a horse with. As an example: Say a person has a really nice mare Possible TB, but can't proove parentage. Mare has been competing in (insert event of your choice) and winning/placing well. Mare is nice tempered, well conformed and has a performance record. BUT she doesn't have a pedigree. Owner wants to breed said mare and wants foal to be registered so Owner looks for registries that will accept foals of partially unknown parentage. ( ie Half Arab, Pinto, Half Peruvian Paso, Appaloosa for Appaloosa sport horse Etc) Foal gets registration papers because Stallion is registered and has all pedigree information. What is your opinion on said foals value and the Value of the Half-whatever Papers?
