How long are goats pregnant?

Goats carry for about 150 days, five months, with most does kidding between days 145 and 155. Pygmy and Nigerian Dwarf goats are often a few days shorter.

Kidding date = breeding date + 150 days

DayWhat to do
18 to 21Watch for a return to heat, which means she did not settle
30 to 45Ultrasound or blood test to confirm
About 100Dry off dairy does
About 120CDT booster so kids get antibodies in colostrum
145 to 155Kidding window
Signs of kidding. Tail ligaments soften and seem to disappear, the udder fills tight, and the doe paws, talks and looks for a quiet spot. Call your vet if she pushes hard for more than 30 minutes without a kid.

See the goat gestation chart for every breeding date, and compare with sheep, which carry for 147 days.

How can I tell if a goat is pregnant?

The reliable checks are an ultrasound or a blood pregnancy test from about 30 days after breeding. At home, watch for no return to heat 18 to 21 days after breeding, a belly that grows on the right side from about month 3, and an udder that fills in the last month.
