Nutrition for Pregnant Mares

When excitement gathers of the expectant foal there are many things to consider and among them, prenatal nutrition for the mothers to be, especially during their last trimester where significant foal growth occures.

Our mares are a very important part of how Pureform Farms and Pureform Equine Health Supplements has been developed. It is with 24 years of love, respect and the long hours studying to develope the best nutritional concentrates to enhance each mares’ chances of a successful birth, fast recovery and a foal with strong legs and good minds. We are very thankful that with all of the dedication to have a fruitful, high mortality rate of 60 & 0. What else could you ask for as a breeder.


The nutritional program will always start out with the type of hay you choose and knowing the nutritional specs through a microbial analysis of that dry forage or live pasture grasses. Important factors are going to be the micro nutrients like calcium : phosphorous ratio, selenium, vitamin E and of course protein content. Most equine nutritionist quote; Harold Hintz, PhD, MS, professor of animal nutrition at Cornell University, in his chapter titled "Nutrition of the Broodmare" in the textbook Equine Reproduction. In which he states pregnant mares require 9-10% protein in their combined diet of hay and grain. When lactating, their protein requirement increases to 12%, then decreases to 10% in late lactation. Again, how do you know the protein content but a core analysis of the very basic hay type. Whether you are buying large quantities from a broker, farmer or smaller truck load from your local feed store, ask if the grower has the analysis available or have it core test on your own, which should not cost more than $40 at a reputable lab.


The truth is, under ideal circumstances (good fresh pasture grasses) your mare would blossom, especially knowing the selenium, vitamin E, calcium and phosphorus nutrients are sufficient. With this you would only need to supplement with iodized salt and maybe grain if needed for extra weight or protein. Fresh pasture will hold a protein content of 6-8% and calcium and phosphorous ratio of 1.2:1 or close but once cut and dried, the grass loses its vitamin and mineral profile significantly. Most researchers feel the ideal balance is about 1.2 parts calcium to 1 part phosphorus, up to about 2:1. Excess dietary phosphorus, in any form, binds calcium and prevents its absorption, but the same is not true in reverse; excess calcium has almost no effect on the absorption of phosphorus.


With the ideal pasture not the norm or available for most breeders, our bio chemists have calculated the ideals in numbers in relationship to forage complimentary nutrition. Our PUREFORM All-In-One Equine Health supplement concentrates are formulated with a full spectrum of highly absorbable vitamins, essential amino acids, antioxidants, digestive yeasts and minerals with different amounts of calcium and phosphorous depending on your hay type. If you are not sure, a simple call or email to our office and the conversation of clarity can begin.


Beware: There are a few nutrients to beware of when given in excess. For instance, Iodine is a micro mineral that is in mineral blocks or iodized loose salt and also high in kelp/seaweed meal. The total should be calculated.


We are here to help you build a solid and successful breeding program.
