In pen breeding, the buck/ram is put in a pen of does/ewes to facilitate their mating. It is, however, quite labor intensive, requiring the manager to accurately identify the doe/ewe in heat and facilitate the mating.Ģ. This method has the advantage of allowing the exact breeding date to be recorded. This method involves selecting the buck/ram for the doe/ewe and mating them. There are four main breeding systems commonly employed in the goat and sheep industry:ġ.
It is critical to decide on a breeding system that fits your production plan. If a natural breeding program is utilized, you may have little or no milk being produced during January and February. Estrus lasts from 12 to 48 hours, and ovulation occurs 24 to 36 hours after the onset of estrus.īecause goats and sheep are seasonal breeders, it can be advantageous to utilize reproductive technologies to ensure a year- round milk supply. Detection should take place at least twice daily, separated by 12 hours. The key to success with this system is housing the males and females apart prior to putting them together.Įstrus observation should be avoided at feeding or milking, as signs may not be as obvious. Even during the nonbreeding season, some females will display estrus and ovulate due to the male effect. When a buck or ram is introduced to a group of females, he stimulates the onset of estrus. The presence of a male in a neighboring pen will stimulate more obvious signs of estrus.
