In mares, the majority of fetal growth occurs in the last three months of pregnancy. Because they do not have to support rapid fetal growth, mares in early pregnancy can be fed much like a horse at maintenance.
Stallion diets, like those of other horses, should be based on good-quality forage with concentrates added to supply sufficient energy for whatever work the horses are being asked to perform.
Embryo transfer (ET) is an important part of many breeding programs. Breeding managers consider the genetics of the donor mare and the stallion, but both nutrition and a “newer” field of genetics—called epigenetics—also greatly influence the growth and development of the foal.
I have a young Mustang mare with a foal at her side. She is underweight, but I don’t know what I should be feeding her. Please help.
There is some speculation that the physical presence of the maturing fetus decreases the volume of the intestinal tract, potentially decreasing overall dry matter intake.
A stallion’s fertility seems to have decreased at around the same time his diet changed. How can I get his feed tested?
The trace minerals copper and zinc are required for normal growth, development, and immune function in young horses. Nutrition of the mare during pregnancy and the young foal in the month after birth are also critical to proper development of weanling and yearling horses.
A recent study of broodmare fertility showed horses stay healthiest and most content when their feeding plan closely follows the natural pattern.
Though vitamin deficiencies often bear the blame for fertility issues in broodmares, energy balance is a far more likely nutrition-related reason for subpar reproductive performance. Appropriate body condition is one important factor in broodmare performance.
How do I feed a retired dressage mare that is now five months pregnant and that generally stays fat on little feed?
