Herbs for Breeding, Gestation, and Foaling

Preparing a mare for breeding should begin long before she is introduced to the stallion. Mares should be kept in good physical shape, receiving optimum nutrition, ample exercise and turnout, and regular hoof and dental maintenance. After the mare has been herbally cleansed and toned (see premier issue, Fertile or Fallow?), she will be ready for breeding. Patti Duffy-Salmon, certified herbologist, again shares her considerable knowledge, and cautions owners about the use of herbs during gestation.

Ready for the breeding shed

One of the two herbal blends previously mentioned to help tone and strengthen the system, enhance fertility, and prevent infection (see premier issue, Fertile or Fallow?) can be fed up until the time of breeding. After the mare has been covered by the stallion, however, herbs should be stopped immediately until an ultrasound has been performed. If the mare is not in foal, the blend may be resumed again, but always stop any herbal preparations once the mare has been covered.

Gestation

During gestation, one must be very careful about giving the mare herbs. Proper nutrition is essential, and high quality feed should be provided. Attempts to supplement herbally, however, may be counterproductive, and could be harmful. Any herb that may be considered a muscle relaxant or a stimulant should be avoided, and any herb that may promote cycling should be avoided.
Patti cautions, "The following is a lengthy list of herbs that should never be fed to horses during gestation:

This is quite a long list, and it includes some commonly used herbs. As you can see, I do not use many herbs during the gestation period. Kelp is one that is pretty safe during pregnancy, as long as it is not overfed. Recommended kelp levels for a pregnant mare should only be around 1 tablespoon two times daily. It is a great source of naturally occurring minerals (alfalfa is the highest land source of naturally occurring minerals), and is very beneficial to horses. This sea herb’s primary benefit is to help prevent iodine deficiency. Kelp is useful for under active thyroid glands and goiter, rheumatism, and rheumatoid arthritis, for which it can be used internally and applied externally on inflamed joints. Kelp also can improve the quality of the hooves.

Comfrey is listed by some sources as useful during pregnancy, but I don't feed comfrey, leaf or root, during pregnancy. It feeds the pituitary gland with natural hormones. I may use it up until breeding, but not after. Comfrey has been used for centuries as a wound-healer and bone knitter. It helps to balance the calcium-phosphorus ratio. Comfrey is rich in vitamins A and C. Comfrey will help with gastric upset, duodenal ulcers and ulcerative colitis. It has astringent properties and will help with controlling of bleeding, such as bleeding ulcers. Comfrey maybe used externally as a poultice to aid in broken bones and guard against scar tissue production, such as proud flesh, with horses.

Raspberry leaf can be safely fed during the last 2 months of gestation only, along with chamomile flowers, in the dried form, added to the feed. It will help tone the uterus in preparation for delivery. Only small amounts of raspberry leaf should be fed to the mares.
  For delivery, I again would only use raspberry leaf. A mare should not need any herbal stimulant - she will deliver when she is good and ready. If the mare has a retained placenta, then a small amount of Blue cohosh may be helpful. Blue cohosh may be fed during the week the mare is due to foal, but no sooner. It will help to stretch the neck of the uterus and aid in delivery. Blue cohosh should be fed along with black cohosh, again, only in small amounts and only during the last week of gestation, no sooner. If problems are encountered during gestation, other forms of natural therapy may be explored.

After the foal is born,  raspberry leaf may be continued to help the uterus get back into shape. Fennel and blessed thistle may also be fed. Blessed thistle and fennel seed are excellent for milk production. Garlic, however, may taint the taste of the mare's milk, so please avoid it during the early part of lactation.

Herbs can be beneficial to the broodmare when used sensibly. Always consult with a qualified, equine herbologist before  adding herbs to your equine maintenance program.
