Below are some of the frequently asked questions on the goat gestation period, goat pregnancy, goat gestation calendar, goat kidding and heat cycle.

What is the gestation period for a goat or how long is a goat pregnant?

Goats have a gestation period of 145 to 155 days or 150 days on average. Our goat gestation calculator at the top of this page will enable you to know the estimated kidding due date of your pregnant doe.

What is the heat or estrus cycle of goat?

The heat or estrus cycle in goats is 18 to 24 days (average of 21 days). Each heat period usually lasts between 12 to 36 hours. This means a female goat will only allow a buck to mount on (or service) her between 12 to 36 hours. If eventually there is no mating, or fertilization didn’t occur, the doe will come on another heat after 18 – 24 days.

What is a Goat Gestation Table, Calendar or Chart?

The gestation chart/calendar or breeding chart is used to determine the estimated kidding due date. The chart or calendar is very similar to the normal calendar which starts from January 1 to December 31, but estimated gestation dates are also available for each breeding date. Check the picture below for our sample goat gestation table or chart.
