In Delaware and surrounding states the breeding season for horses begins in mid-February and normally ends in mid-July. However, the physiological breeding season starts in mid-April and peaks in late May or early June, according to University of Delaware ex tension equine specialist, Mel Reitnour. During this period, mares usually experience regular heat periods, ovulating 24 to 48 hours prior to the end of heat. Seasonal factors which influence a mare’s estrous cycle include length of daylight, nutrition, and temperature. According to Reit nour, the ratio of daylight hours to darkness throughout the year acts on the optic nerve of the eye and, along with nerve impulses, affects the hypothalmus or pituitary FILLIPPO, INC.

The result is production ot FSH (follicle stimulating hor mone), which stimulates the production of estrogen, causing heat. Artificial light can be used to increase the hours of daylight, thus inducing the estrous cycle to begin early. Artificial lighting will bring mares in season about six weeks earlier than normal, Reitnour says. Research shows that 16 hours of light per day will initiate estrus and ovulation. Artificial lighting for a mare that normally conceives on April 15 may get her in foal some time in February. This practice could produce two ad ditional foals during the mare’s lifetime. The specialist recommends using a 200-watt light biilb in a box stall to extend hours of light to 16 daily. Light treatment started about December 1 should have FRANK A.

Use of artificial lighting has proved to be a successful way to improve the reproductive ef ficiency of barren and maiden mares. _ Generator Sets Manufactured for Agriculture •Air Cooig&Unite: 2z2OW Maxi-Power Generator has over 325 automatic units in South Eastern Pa.
