Oiling the Wheels - using oil as a supplement in the diet of racehorses

Historically, oil has not featured highly in the diets of horses in training, or indeed those of other horses. The natural oil content of pasture and other forages is quite low at between 2-3% on a dry matter basis, yet despite this, horses digest oil extremely well. Oil added to the racehorses’ diet is tolerated well, with no major palatability problems having been reported.
