"While Jockey Club officials will begin to assess totals submitted by stallion owners this month, the estimated foal crop this year is 27,000 -- a 10 percent drop over the prior year and the lowest number since 1973, says Club spokesman John Cooney. The registered foal crop has steadily decreased since 2007, now approximately one-fifth its size then."

"A shot of Lasix costs $26 retail. Some vets will administer it for $20. But the accompanying drug regimen before and after the injection often runs the race-day cost to $200 or more. The race-prep veterinary work for one of the most honest, cost-conscious trainers in the business regularly included a $16 bute injection, a $25 injection of acetylcysteine designed to break up lung mucuous, a $30 Salix shot on race day and $49 worth of replacement fluids and electrolytes the day following.... That means that some owners pay more than $400 per month for Lasix and bute alone. Add $800 worth of the prescription ulcer medicine -- omeprazole -- some version of which almost every American racehorse requires -- and the meaning of the word 'mark' quickly becomes clear."
