Should a pregnant mare at any time during her gestation be allowed to graze on grass contaminated with endophytes? Some say it is ok as long as the mare is removed 60 days prior to delivery. I think this is rediculous. Thanks - Horses [Skip to Content]

ANSWER

A large amount of data has been collected in regard to fescue toxicity is mares at all stages of pregnancy. There have been no detrimental effects of endophyte infected fescue on mares in early and mid gestation observe. However, mares in the last trimester of gestation can have complications as a result of grazing endophyte infected fescue pastures. These complications may include abortion, prolonged gestation, agalactia, foaling difficulty and retained placents. Research has also shown that if pregnant mares are removed from the endophyte infected fescue pasture 60-90 days prior to their expected foaling date these complications are eliminated.
