Sometimes the doe will make sounds similar to those of the buck. During standing heat, some does cry out as if in pain. When successful copulation occurs, the buck will throw his head back as he ejaculates his semen. Mating activity will actually bring other does into heat. Particularly in hot climates, nighttime breeding is common because the nights are cooler.
Breeding takes a great deal of energy by both buck and doe.
Breeding bucks need to be in sound physical condition, because during mating season they go 'off feed' and may lose as much as 50 pounds. It is important to offer the bucks quality rations during breeding season in order to keep them in good shape. Females do not usually go 'off feed' during breeding to the extent that bucks do, but it is important that their nutritional needs are addressed prior to breeding. The condition of the doe at breeding time has a huge impact on the resulting offspring. Remember that a doe can short-cycle or have false heats, particularly if breeding is attempted while she is still nursing kids.
