The importance of trace minerals in late pregnancy by Optim Equine Camilla Whishaw

The importance of trace minerals in late pregnancy

During late pregnancy, a mare’s nutritional requirements increase to meet the demands of her rapidly growing foetus.

When feeding heavily pregnant mares, many focus primarily on providing increased calories to the mare. Unfortunately, the importance of trace minerals often gets overlooked. 

Zinc, selenium and copper in particular are low in mares milk. For a foal’s requirements of these minerals to be met, the pregnant mare must have received sufficient amounts of these during pregnancy (and as research continues to support, even prior to pregnancy). This allows the unborn foal’s liver to be fortified with these nutrients prior to birth. 

The foal draws upon the supplies of these minerals from the liver for the first couple of months of life. This is essential to support healthy skeletal growth. Insufficient stores of these trace minerals may predispose foals to growth disorders and conditions such as osteochondrosis and osteochondritis dissecans (OCD).
