Condiments are agents which stimulate the appetite, but do not supply material that can be utilised in the nourishment of the system. Fortunately for horses, the use of condiments has almost entirely gone out of fashion. Lawes and Gilbert state, with reference to the feeding of sheep, that "in both of the comparative experiments, more food was consumed to produce a given amount of increase with Thorley's Food, than without." The use of tonics and alteratives should be restricted to cases of illness, which should be treated, if possible, only by a veterinary surgeon.
