There's probably no objective data on "laming rate". But you can
probably find numbers to get a "percent raced". Assuming that
roughly 30,000 TBs are registered a year, a 5% "percent raced" would
be .05*30000 = 1,500 2-yr-olds raced. Is this high? Low? Of
course, the 30,000 registered includes animals that were never bred
to race (pleasure horses, for example).
Probably a more accurate measure of "breakdown" would be 3-yr-olds
vs. 2-yr-olds from the previous year. Some 3-yr-olds would not have
been raced as 2-yr-olds, though, so this number would not be
entirely accurate either. You might, for example, have data that
shows more 3-yr olds racing than 2-yr olds the year before
(n3/n2>1.0). And horses can be retired for reasons that are not
entirely health related (case of the 'slows', horse sold for
delinquent training fees, etc.). OTOH, horses can have subclinical
health problems that contribute to "the slows" but aren't identified
as a specific lameness or injury.
Interesting question, but the data may be hard to get at.
