What is the typical duration of estrus (heat) in gilts?

The typical duration of estrus (heat) in gilts is around 12 to 36 hours. During this time, the gilt exhibits signs of receptiveness to mating, which can include behaviors such as standing still when pressure is applied to the back and increased vocalization. Understanding this window is crucial for successful breeding practices, as it helps farmers effectively determine the optimal times for artificial insemination or natural mating.

While there are various factors that can influence the exact duration of estrus in different animals, the commonly accepted range for gilts is indeed 12 to 36 hours, which reflects the physiological and behavioral changes occurring during the reproductive cycle. In contrast, other durations listed in the options extend beyond the typical timeframe for gilts, which may lead to confusion in breeding logistics if misunderstood.
