DUNSTAN -  Feeding Pregnant Mares

Nutrition Tips for Expectant Equine Mothers!

Nutrition of the pregnant mare has a huge impact on the subsequent foal. Ensuring that the mare maintains adequate body condition is important (without becoming overweight) as this ensures she has sufficient body condition to take on the energy demands of lactation once she has foaled. If the mare is to be re-bred, maintaining adequate body condition will improve the likelihood of early conception.

The last trimester of the mare’s pregnancy is a critical time to provide her with the appropriate intakes of key trace minerals including Copper, Zinc, Selenium and Manganese. If this is done, it will assist in the development of a sound skeleton in the subsequent foal and the future athlete.

The way in which these key nutrients will be provided will depend on the individual mare (her metabolic rate) and pasture availability. Mares which are lighter and require hard feed to maintain condition will receive adequate nutrient intake in their last trimester if fed a good quality premixed feed such as Dunstan Breed and Grow at a minimum of 2.5kg daily (based on a 500kg bodyweight). Dunstan Breed and Grow is a low GI, high-fibre, low-starch complete feed which includes organic minerals, and contains natural vitamin E. It is specifically formulated for pregnant and lactating mares and young stock.

However, inadequate supplementation will arise if a full feed is not being fed at the recommended intake.

In the situation where mares are holding sufficient body condition and do not require the recommended intake of a full feed, a more concentrated source of supplementary feed is appropriate – a feed that provides more nutrients per kg. Dunstan Multi-Ultra or Dunstan Pasture Plus can be used in this situation. Both products are low intake supplements, Dunstan Pasture Plus (250grams per day) or Dunstan Multi-Ultra (500grams per day). These concentrates will provide a similar contribution of vitamins and minerals to the ration at these low intakes as a full feed will when fed at 2.5kg daily. Fed to mares in their last trimester they will provide an adequate intake of key nutrients required by the unborn foal.

Once mares have foaled, their energy requirements increase to meet the demands of lactation. Dunstan Breed and Grow is still the most suitable supplementary feed after foaling, however intakes will need to be increased for ‘lighter’ mares.

Mares that really struggle with condition during lactation may benefit from the addition of a high fat supplement such as Dunstan Muscle ‘n Shine or Dunstan Trifecta Oil.

Dunstan Breed and Grow is also the ideal first-feed for the foal to share with the mare. As Dunstan Breed and Grow is a low GI formulation, calories are provided by fibre sources rather than starch-laden grains. Therefore it is a safer and more digestible feed for the young horse. In addition, the low GI nature of Dunstan Breed and Grow helps to minimise the negative impact that insulin can have on the development of joints and cartilage - all important for a growing a sound skeleton.
