I’m confused. Jackie are you saying that TBs don’t have high knee action?[/QUOTE]
The TB has never been selected and BRED for high knee action. Early on foundation stock of the TB did not interfere as much with high knee action (TB outcrosses were used to create the Hackney, Morgan, Standardbred, Yorkshire Trotters and Cleveland Bay breeds) but they did not add to the high knee action as such. As far as I know none of the above breeds kept on adding TB blood like the WB breeders have for the last century.
The only horses I’ve seen (in person or on videos) who, trotting loose, have the same type of trot of the WB is the American Saddlebred, a breed who has avoided direct TB crosses in spite of being developed in the center of American TB breeding, Kentucky. This is why I recommended them many, many pages ago as a possible refining outcross that possibly would not kill the WB jump, though they could add many conformational faults that the WB breeders have successfully removed from their mare lines.
In preparation to getting the books on the Holsteiner I am re-reading “Points of the Horse” by M. Horace Hayes since he often compares the differences between the conformation of the TB, hunter, light draft/carriage horses, heavy vanners and draft horses. One comment he made was that if a TB colt in Great Britain was not good enough to win on the flat he was GELDED and turned into a steeplechase horse or hunter. There were some exceptions, the Man O’War son Battleship (who won the Grand National steeplechase in England) remained a stallion and bred on. I do not know how successfully Battleship bred on, just that he did.
I am getting the impression from my research that the WB trot and the WB jump come from the European native mare lines ONLY. The TBs and other hot bloods added riding qualities, speed, stamina, refinement, athletic ability, and the TB adds heighth, but the modern TB genome does not necessarily add anything to the WB trot or WB jump. Since the TB in part descended from the native British horses (Galloways especially, bred for speed in Great Britain long, long ago) there MAY still be genes of the native European horse “jump” and trot in the TB genetic code, but since it does not seem to add to TB speed on the flat it has not been bred for and most of the colts showing any sign of this ability tend to be gelded. Could TB lines be developed that did not “kill the jump”? MAYBE. Is anyone going to pour a lot of money and time into developing these TB lines that can’t win the big pursed flat races? Probably not. It would probably take the assets of a billionaire to succeed, and I don’t see many of the present day billionaires stepping up to do so. (Bill Gates daughter has gotten into riding, maybe WB breeders should talk to her about doing this breeding project.)
