Frequently Asked Questions
How long is a sheep pregnancy?
A ewe pregnancy averages 147 days, with a natural range of about 142 to 152 days.
Why is a full 10-day window given around the average date?
Individual ewes vary enough in gestation length that a single fixed date would be misleading. A window centered on the 147-day average gives a more realistic sense of when lambing is likely to happen.
How does sheep gestation compare to goat gestation?
Sheep gestation, at 147 days, is fairly close to standard-breed goat gestation, around 150 days, since both are similarly sized ruminants with broadly comparable reproductive biology.
