Caring for the Pregnant Horse

First published May 2013 · Revised 2026

Eleven months of carrying, a delivery that asks everything she has, and months of nursing after that. A pregnant mare's body performs remarkably when it has what it needs.

What pregnancy asks of her

Three jobs, back to back to back.

Pregnancy brings real health concerns for both mare and foal, and while most are everyday matters, none of them should be taken lightly. The stresses of carrying, delivering, and nursing a foal are considerable, and they land one after another, each drawing on whatever reserves the last one left behind.

01 · Carrying
Keeping her robust

Full of energy through eleven months of growing a foal, so she arrives at delivery with reserves to spend.

02 · Foaling
The delivery itself

The exertion and endurance demands of birth are considerable. The best possible health going in matters most right here.

03 · After
Bouncing back, then nursing

Her body has to rebuild while feeding a growing foal, whose bone and ligament growth depends on what she takes in.

Our philosophy is simple

Feed the mare well, and she feeds them both.

When a mare is sound and nutritionally robust, her body can perform remarkably well. And her nutrition matters just as much before the foal arrives as it does afterward, through her bounce-back and then through nursing, when the foal's whole diet is whatever she has to give.

That's where the Nzymes Sprouted Granules come in: live superfood protein added to her daily feed, easy to give and economical even for large horses. Start with a doubled amount for her weight, mixed into her feed or fed by hand. We believe the Granules promote easier birthing, a faster bounce-back for the mare, and healthy, balanced growth for the foal, and the same support can continue with the foal once it's on regular food.

Questions horse owners ask
When should I start the Granules with a pregnant mare?

As soon as you know she's carrying, at a doubled amount for her weight, added to her daily feed or fed by hand. Nutrition matters just as much before delivery as it does afterward, through her bounce-back and nursing.

Does the foal benefit too?

The mare's nutrition is the foal's nutrition, through the womb and then through nursing. Continued use supports the foal's growth and development, including bone and ligament growth, and the Granules can continue with the foal once it's on regular food.

How much do I give a horse?

The dose runs by weight, from 3 level teaspoons daily for horses of 600 to 750 pounds up to 6 for 1,251 to 1,500 pounds, doubled during pregnancy. Add it to feed or offer it by hand; horses genuinely like the taste.

Is this a substitute for veterinary care during pregnancy?

No. A pregnant mare should have proper veterinary oversight throughout. The Granules are daily nutritional support for the demands pregnancy puts on her body, working alongside good forage, good care, and your vet.
