Lasix VIII
Genetics (continued): Will lasix aided stallions turn the whole gene pool into a bunch of bleeders? Do certain stallions pass on the EIPH gene as per last post. Is there an EIPH gene? Anybody know? Therefore we eliminate lasix due to "genetics".
Counterpoint:
1. There likely are no EIPH stallions that pass on their condition per Bob Baffert. If there are, name them. While we are unable to say with certainty and without statistics that fail to exist, the circumstantial evidence below indicates this premise is another in the fairly large bag of trainer bs.
2. Is there an EIPH gene? I doubt it. Logical analysis indicates EIPH likely is a physical problem initiated by specific pressures on lung capillaries probably in certain weather conditions and exertions. You'd have to think this "gene" developed in this narrow population over a fraction of the normal evolutionary period. But, the question whether EIPH is passed on in certain gene context gets even more absurd. Read on.
3. 95% of the TB racers these days evolved from three stallions--Northern Dancer, Mr. Prospector, Bold Ruler. If you want to trace back further--Native Dancer. And each of these came from Nasrullah. If somebody is passing along a "gene" then are they all, every last one of them.
4. The main (0ld) EIPH study on the % of horses that bleed indicated (if memory serves) that 90% of non-lasix TBs experience some degree of EIPH when racing. If this old study is to be believed, where does that leave the EIPH gene?
5. And, the final nail in the coffin for the "theory": Lasix has been around but 30 years. Are you claiming there has been some genetic adaptation over 2 or three horse generations. And, if you are logical enough to avoid claiming that, where did all these bleeders come from. Answer: the EIPH that there is today was around before lasix ever entered the scene.
That EIPH is inherited at this point without further study would be totally speculative and there's very little that I can think of that would support it. Hilariously, my one serious bleeder derives from my broodmare that was by English Champion Wind and Wuthering. They never produce bleeders over there in Europe, do they?
