Tesio In His Own Words (e-book)
http://www.horseinfo.com/cart/tesio.html
Hi Nanakat,
Here's an idea I have had rumbling around in my head the last 24 hours. Try this one on for size. We know that transgenerational epigenetics can inherit to at least the F2 generation ( grandkids). We see this in humans and turkeys. Are you familiar with Tesio the great racehorse breeder? Years ago I bought his reprinted book , "Tesio in His Own Words". A fascinating tome on how he bred his superlative racehorses. Here's where it gets interesting. Tesio was a polymath. He tried for years to come up with an equation which would result in the perfect balance between speed and form. He failed and finally went to see a clergyman. The clergyman told him that it couldn't be done and the road to such perfect balance lay in complementary breedings. In balancing attributes until balance was achieved. ( as a side note, the most perfect racehorse ever bred was Eclipse. So perfect in form and symmetry that he never "fought against himself" when racing and that's why he was such a winning horse) but I digress.
Anyway, Tesio took the advice to heart. He created a superlative stud farm and bred the finest racehorses ever. No one could figure out how he did it. Nor could they replicate his results. When his book was found and reprinted Tesio revealed he used the "nervous energy" of young studs.as older studs had worked for years and their nervous energy was depleted. Ok, that sounds kinda New Age unless we take in some other ideas.
Ok, stay with me here.... In Ohio about the same time, there was another renowned polymath who was a Prof. at Ohio State University. .He bred horses and collie dogs. Prof. Bohannon decided to trace the heritage of the top winning collie dog ( rough [and possibly] smooth coated) studs of his day and before. He made a great chart listing the studs and the ages at which they begat their winning get. ( I have the chart, being a very serious student of the collie breed) The numbers tied in with Tesio's research in that the most successful get from these collie studs were begat when the dogs were younger.
Now let's put these thoughts aside for a moment and go back to the transgenerational epigenetics and linebreeding. If we were closely linebreeding our birds and we end up seeing a transgenerational epigenetics trait. Could we actually be linebreeding that trait if we got no further than F2 generation at any time? ( as an aside Tesio did an exhaustive study of winning male stakes racehorses and their get. He found that the sire would win; the son would win; the grandson would win... but the winning never, ever passed on to the F3 generation. Not once. I sometimes wonder ( dog breeding having arisen somewhat from the horsey crowd..if this is where we got the old adage "2 generations and out" , meaning inbreed 2 generations and then go out for new blood).
What I do not know is the vitality of the epigenetic "tags" we talked about earlier. Do they fade in vitality or ability to accept epigenetic commands? If they do ..and... the best time for one of the tags to accept a epigenetic "command" would be when the animal was younger... hang in here with me.... I wonder if Tesio in his complementary breedings stumbled on transgenerational epigenetic traits. Could they be the "nervous energy" he spoke of? And if so ,and if the tags do lose vitality later in life, could that be why the collies and horse studs begat their greatest get when they were young.? Could Tesio have actually be linebreeding transgenerational epigenetic traits? Was that why others couldn't replicate his results? Because they brought in (or just plain used) foreign blood and the traits went past the F2 generation or were strain crossed and didn't manifest any more .
It's an intriguing line of thought, However...I need to talk to some experts about this and learn more about the epigenetic tags. Until I can understand how they work, there's not much further to go with this. Racehorse breeding is such a fine art, it has always intrigued me why folk couldn't replicate Tesio's success.
Another explanation might be...we know (as animals age) microsatellites in their genome change. Maybe this was the "nervous" energy Tesio spoke about. The younger the stud, the less time it's genome has to "change".
Best,
Karen
