What is the typical estrous cycle length for goats?

• A. 28-32 days
• B. 40-60 days
• C. 18-22 days
• D. 9-12 days

Answer: (C)

Goats have an estrous cycle that repeats roughly every three weeks. The length of the cycle is the interval from one ovulation-driven cycle to the next, and in goats this is typically 18 to 22 days. Averages cluster around 21 days, with some individual variation. The estrus itself lasts about a day or two, during which the doe is receptive to a buck, and ovulation tends to occur toward the end of estrus. Because of this pattern, 18–22 days best fits the normal timing for does. Longer ranges like 28–32 days are not typical for goats and are more associated with other species or irregular cycles, while a very short 9–12 day window does not align with the goat ovarian cycle.
