What is the typical gestation length of a domestic sheep?

The typical gestation length of a domestic sheep is about 147 days.

Sheep pregnancy usually lasts close to five months, although the exact duration varies with breed, litter size, nutrition, and the individual ewe. Farmers use the breeding date and the expected lambing window to prepare shelter, feed, and assistance if necessary.

A gestation of about 147 days is a useful average rather than an unchanging biological rule. Ewes carrying twins or triplets can differ slightly from ewes carrying a single lamb, and seasonal breeding patterns influence when pregnancies begin. Most sheep breeds are seasonal breeders, with mating often concentrated during shorter-day periods.

Sheep gestation is notably longer than pig gestation, which is commonly remembered as about 114 days, and far shorter than cattle gestation, which is roughly 283 days. After birth, the offspring are called lambs. Correctly identifying the species is important because livestock gestation figures are often mixed up in basic animal trivia.
