A light-based method of inducing physiological change, the method comprising the nstep of shining light from an artificial blue light source into just one eye of a female nhorse or other animal, each day for at least 6 weeks, causing a substantial nsuppression of melatonin production sufficient to induce physiological change, the nphysiological change being advancing a breeding season of the horse or other nanimal, wherein the treatment regime is at least as effective as maintaining the horse nor other animal indoors under barn lighting to advance the breeding season of the nhorse or other animal. |
