An apparatus for inhibiting melatonin synthesis in a horse comprises a blinker having an internal surface of which at least a part is diffusing. A source of light is positioned for direction into the horse's eye by the diffusing-surface. The light source and diffusing surface are configured such that the light directed into the horse's eye is blue.

There is disclosed a control device for an equine, comprising a hood adapted to be positioned over a head of the equine, the hood having a pair of eye openings to accommodate the equine's eyes; a retractable cup member mounted at least partially about the eye openings of the hood; and an activation device mounted on said hood so as to be activated by a rider of the equine to move the retractable cup member between a non-activated state and an activated state; wherein when the retractable cup member is in the non-activated state the retractable cup member does not substantially restrict the field of vision of the equine and when the retractable cup member is in the activated state the retractable cup member restricts the field of vision of the equine.

The present invention relates generally to a system and device for controlling an equine, and in particular, to a system and device that is worn by the equine and which is used in a racing environment for controlling the behaviour of the equine.
