Foal On Time with Optimum Birth Weights
An unfortunate side effect for mares with foaling dates that occur unnaturally early in the year is longer gestations and smaller foals. Environmental light influences the development of the foal in utero and regulates when a mare will foal. Nature intended that foals be born during the longer days of late spring and summer – and nature tends to have her way. Stimulating the longer day lengths associated with the natural breeding season by fitting pregnant mares with Equilume Light Masks has been shown in clinical trials to eliminate these side effects in most mares, instead helping the mare deliver her foal on-time and with an optimum birth weight.
Late-foaling mares represent economic loss to the breeder by reducing the number of foals a mare can produce in consecutive years. Mares that foal during the darker days prior to the natural breeding season (e.g. Thoroughbreds) have longer gestation lengths by an average of 10 days. However, 20% of Thoroughbred mares experience annual gestation lengths that exceed 355 days.
Light is the primary influencer of gestation length. Light therapy prior to foaling has been scientifically shown to increase average foal birth weights and prevent prolonged gestation. See our research here.
