Below is some of the FAQs on the gestation of sheep, pregnancy, gestation calendar, sheep lambing and heat cycle.

What is the gestation period for sheep or how long are sheep pregnant?

Sheep have a gestation period that is similar to goats. The gestation period of sheep is 142 to 152 days or 147 days on average. Use the sheep gestation calculator above to determine the estimated lambing date of your pregnant sheep.

What is the oestrus or heat cycle of sheep?

Sheep oestrus or heat cycle length is 14 to 19 days or 17 days on an average. When a ewe comes on heat, the heat often lasts for 24 to 36 hours. So this means if a ewe is unable to be serviced by a ram within 1 to 1½ days or fertilization didn’t occur, the ewe will be on it in another 14 – 24 days.
