cow and calf gestation

We have provided answers to some frequently asked questions on cattle/cow gestation, pregnancy and gestation table, breeding calendar and heat cycle.

How long is a cow pregnant or what is the gestation period for a cow?

The gestation of a cow is 279 – 287 days and an average of 283 days. Our cow gestation calculator above will help you to calculate the estimated calving due date of your pregnant cow.

What is the heat cycle of cows?

Cows usually come on heat (oestrus) every 18 – 24 days and the heat lasts for 18 hours. After about 12 hours that the cow comes off heat, ovulation starts. So if the cow didn’t get a bull to service her or fertilization didn’t occur, she would come on heat after another 18 – 24 days.

What is a Cattle / Cow Gestation Table / Calendar / Chart?

The gestation table calendar or chat is a table that can be used to easily know the estimated calf due date by just checking the date of service or mating. The calendar or chart is designed just like a calendar starting from 1st January to 31st December and beside each day is the estimated due date. Check the pictures below for our sample cattle/cow gestation table or chart.
