Estrus, or heat, is the period in which the doe will stand and allow the buck to breed her. This phase of the reproductive cycle may last between 12 to 36 hours. The period from one heat cycle to the next is referred to as the estrous cycle. In goats, the estrous cycle occurs every 18 to 24 days, or 21 days on average.
  Breeding goats depends on the breed of goat and where you live. Dairy goats (Saanen, Oberhasli, Alpine, etc) are able to be bred in the fall. They can take from late Aug â¦ ust to probably December. Other goats, like meat goats can be bred year round, depending on how cool the climate is.
