What is the average length of the estrous cycle for a ewe?

14 days
17 days
21 days
24 days

The correct answer is: 17 days

The average length of the estrous cycle for a ewe is approximately 17 days. This cycle consists of several phases, including proestrus, estrus, metestrus, and diestrus. During the estrus phase, the ewe is receptive to mating, which typically lasts for about 24-36 hours, and this phase is essential for breeding management in sheep production. Understanding the average estrous cycle length is crucial for sheep breeders as it helps in planning breeding schedules and ensuring optimal chances for successful mating. Ewes that experience a consistent 17-day estrous cycle allow producers to anticipate when to introduce rams for breeding and improve flock reproduction rates. This knowledge also aids in the selection of breeding times that align with feeding and management practices, enhancing overall flock productivity.
