Increasing Oxygen Concentration in the Blood of the Racehorse
/Oxygen is the fuel of life and its efficient use is the key to athletic
fitness. The respiratory system of the racehorse must work hard to
harvest the 20 percent of oxygen present in the air we all breathe.
Observing a horse after his work on a cold morning provides a visual
reminder of this, as the breath surges from his nostrils.
