I don’t think this colt should be bred. Without a performance and/or produce record, bloodlines are nothing but lines on a piece of paper. Look at human families, I’m one of four siblings, skills, athleticism, and some might say intelligence varies greatly amongst us. In my experience it tends to be similar for horse families. Look at most broodmare produce records, the vast majority of the time the records of her offspring vary tremendously. It’s a rare broodmare that consistently produces outstanding foal after outstanding foal. When someone says to me, I’ve got a mare, never shown or produced but she’s a full sister to x, a picture of my full sister pops into my head, four inches shorter than me, asthmatic, but far more intelligent.
I’m sure you TB folks do the same, but I spend a lot of time looking at produce records for AQHA reining studs. Take total number of offspring, minus number not of performing age, divide the number of performing offspring by that number. And you get % of offspring who are performers. Not necessarily great performers, but have some record however small. Average number to come up with for say the top 50 studs in the country? 50% Very small portion of the top 50 might have between 55-65%. So that means 50% of the offspring of the very top reining studs end up with a performance record. And the top reining studs have extensive performance records of their own. 50% offspring with performance records is considered the best breeding odds on paper. That’s pretty risky numbers.
A 501©3 rescue group I feel should set the highest example of responsible breeding. Taking a colt with no performance record (and no one has even mentioned his conformation) and breeding him, in my mind is not setting the highest example.
