We are breeding our Shire mare and Clydesdale mare to Gypsy or Drum stallions this spring using frozen or chilled semen. (The mares are both from good lines and possess superb conformation and temperament; the stallions will, of course, be the very best available.) While we have cared for a mare through pregnancy and parturition, we have not dealt with AI before, so we plan to send our mares to an equine reproduction center for monitoring and insemination. Our question is how long do they need to stay? Obviously we don't want our girls away for any longer than necessary.
But we do want to be sure that everything goes smoothly.
Any advice you have to give would be appreciated!
