Horse breeding considerations — suitability, heritable-condition screening of the stallion, mare/foal care costs, UK overpopulation (UK DEFRA code)

This topic covers breeding decisions under the UK welfare code: whether the horse is a suitable candidate, whether the stallion is free from heritable conditions, the special requirements of mares during pregnancy and foaling, and the UK's horse overpopulation problem.

Claims

  • If you decide to breed from your horse, there are a number of considerations to be taken into account. You should always consider whether your horse is a suitable candidate for breeding, whether the stallion you intend to use has been inspected and is free from heritable conditions and whether you could buy or rehome a youngster rather than breeding a foal.
  • In addition, mares have special requirements during pregnancy, foaling and the post-foaling period and you should make sure you are aware of these before breeding from your mare. The care of a young foal can be expensive and requires a large investment of time, and there is no guarantee that the foal will mature into the animal that you want.
  • At the time of publication of this code, overpopulation of horses is a problem in the UK, and the foal’s individual future should be realistically taken into account.
  • These may include uncastrated males (colts, stallions) and “rigs” (a stallion with undescended testicles or a horse which has been incompletely castrated).
  • Stallions and colts can live with mixed herds but this may lead to unwanted breeding and is not recommended.
