1769.0. "Pregnant mares and fescue" by ANGLIN::DUNTON () Fri Jul 09 1993 20:30

    I just bought my first horse yesterday!  She's a 12 year old mare and
    is two months pregnant.  I know nothing about horses except for what
    I've heard and read.  I am boarding her at a facility that has fescue
    pastures.  I've heard that fescue can cause a mare to abort.  Is this
    true?  Will this be dangerous to the foal so early in pregnancy?

    Yes, grazing on fescue grass is linked to abortion, birth defects and
    other abnormalities like a thickened placenta wall that the foal cannot
    break out of without help.
    
    But, it's not really the grass that is the culprit. It is an endophyte
    (a kind of fungus, I think) infestation that lives on fescue that causes 
    the problem. The endophyte can only infect the grass when it is still seed 
    but, once infected, the grass is always dangerous to all animals(not 
    just horses) that graze it.
    
    There are growers who certify that their fescue seed is endophyte-free.
    Therefore, if the pastures at this facility were seeded with such
    fescue, there should be little danger.
    
    For pastures not grown from certified endophyte-free fescue seed, I 
    believe the current recommendation is that pregnant mares should NOT
    graze such fescue, if at all possible. If that is totally impossible, I 
    believe the recommendation is that they be removed from fescue pastures 
    at least 60 days before foaling.
    
    If it were my mare, I would not let her graze on the fescue at all.
    
    BTW, since this is your first horse and first foaling, I'd suggest you
    read "Blessed Are the Broodmares" by Dr Phyliss Lose so you know what
    to expect between now and the time the foal is weaned next summer/fall.

    I have a friend in Virginia that has to deal with fescue and he 
    foals out several mares a year. 
    
    He has great success pulling them off the fescue 2 to 3 months in 
    advance of foaling and feeding them alfalfa or other good quality 
    hay.  And throughout the pregnancy he feeds a SELENIUM and VIT E 
    supplement.  His mares that go through this kind of management foal
    easily.  Those that don't have a hard time (thickened placenta, 
    no milk, etc.)
