28 Sep Blue Light Benefits for Pregnant Mares – New Research
The horse’s natural reproductive period coincides with the light-filled days of summer. The desire to breed mares early in the year means that many foals are born at a darker time of year than Nature intended. This has consequences for breeding efficiency. Often, early foaling mares experience longer gestations, have smaller foals and can have trouble cycling post-foaling.
As well as hormones that control reproduction, lengthening daylight stimulates important growth hormones that allow foals to mature in utero and mares to produce more milk and good colostrum. Specifically, it is the blue light wavelengths from the sun that drive these seasonal hormonal changes.
Published scientific studies confirm that extending day length for dry mares using blue light from Equilume Light Masks advances reproductive cycles as effectively as stable lighting, with the bonus that mares can be kept at pasture. For pregnant mares, extended daily light from light masks was shown to prevent prolonged gestations (reduction of 10-15 days) and optimise foal birth weights (average 4 kg increase) and foal maturity while improving post-foaling fertility.
