When can I expect my doe to come into heat so she can be bred?

[doncorleone]

As far as breeding goes, there are two "types" of goats:

"Equatorial type" goats that come from climates that are hot all year long. These goats will breed all year long. Examples of these breeds are most meat breeds like Boers, Spanish & Fainting, and also Pygmies and (sometimes) Nubians.
"Alpine type" goats. These are most of the Dairy breeds. These goats are seasonal breeders, like deer, and have a definite breeding season. This usually is from about Aug. to Dec/Jan. The does will come into heat about every 21 days and the bucks will stay in rut during the entire breeding season. Once the buck go out of rut, they loose most of their interest in sex until the next rut.
