Did you know light plays a key role in mare fertility?
As daylight hours drop, mares naturally move into a transitional or anoestrous period meaning they may not cycle normally until the longer days of spring.
Using artificial lighting systems during the winter months helps mimic longer days, stimulating reproductive hormones and encouraging mares to begin cycling earlier. Here at Twemlows, our mares go under the lights through winter to ensure they start cycling by February.
This simple management tool can make a significant difference for studs planning early coverings or embryo work.
