timothy hay for racehorses

Question
hello ma'am. may i know why most of the thoroughbred trainers provide timothy hay as a basic forage to their horses?

Answer
Hello Caine,

Timothy hay is a decent forage for any horse.  It is easily dried and preserved without a lot of mold or dust.  If timothy is cut in early maturity, it can provide adequate nutrient density.  Timothy is also quite easy to grow, being resilient in the face of challenging growing conditions.  These may be the reasons why trainers in your area choose to feed it to racehorses.  

Thanks, Corlena
