>>> You have taken us far afield here.
What I have tried to do is inject some existing realities recognizing the limitations of TCO2 testing, especially if one is going to use those levels to attempt to identify cheaters. The strength of TG figures over other products lays within the attention to detail. The same consideration should be given to this issue.

Well, there\'s lots of pills people use, and you can buy them at the local drugstore: Tums, potassium citrate, etc. They also sprinkle baking soda on the feed. They make up baking soda-electrolyte-sugar capsules and pill the horse. Many horses, of honest trainers, as part of their daily ration get a teaspoon of baking soda sprinkled on their feed.
Alkalinyzing agents are thought to work best within a 4 to 6 hour time period before metabolizing into uselessness - hence why detection barns work.
Here\'s some of the comments from that Stewards education slideshow
http://cobweb2.louisville.edu/eip/Steward_Schools/Medical2007.pdf , regarding southern California TCO2 testing:
- between September 2005 and December 2006, 35,000 samples were tested in southern California, and only three came in over 39 mM/L.
Okay, so what about those 31-35 levels we are all worried about:
- \"26,607 horses looked at, comparing finishing position in race to TCO2 level\" - all horses were between 31.51 and 30.73 mM/L (+/- the standard deviation inherent within testing accuracy) for finishing positions 1st through 14th.
It should be noted that the laboratory standard deviation (that of the equipment used) is greater than that spread. Look at how the winning horses had a higher TCO2 level than horses finishing later - except for those that finished last out of large fields (nearly equal to the winners)
- \"Can a trainer\'s TCO2 averages be used to regulate bicarbonate-loading trainers? Not feasible with an adequate degree of certainty, the most egregious trainers could be identified correctly only 19 out of 20 times\".
- Prior to implementation of measuring all TCO2 levels, and warning trainers if their levels exceeded 36 mM/L, 1.4% of all samples exceeded 36 mM/L. Current rate is 0.2%.
That\'s not alot of milkshaking going on. How many \"move up\" trainers do you have listed as suspicious for milkshaking being the method of choice on the southern California circuit? I think one must look elsewhere on that circuit.
Now, California is an exception, where all horses are tested pre-race. Some jurisdictions only test the winners and one random horse post-race.
