Welcome to our sheep gestation calculator, where you can calculate the delivery date for your pregnant sheep so that you may prepare for the arrival of the little lamb.

Whether you are breeding sheep for agricultural purposes or you are keeping these adorable furballs as pets, you need to know the gestation period of the ewe (find how long do sheep stay pregnant), and keep a sheep gestation calendar at hand to take better care your sheep during their gestation period.

And, if you are interested to learn about the gestation and pregnancy of other livestock animals, you can check out our calculators:

## Sheep gestation calculator

The sheep gestation calculator is a handy tool that allows you to calculate the expected delivery date of a pregnant sheep.

To calculate the lambing date, all you need is the approximate mating date of your sheep, and the calculator will give you the due date along with the expected week. The expected week indicates the earliest and latest possible lambing date.

If you find yourself in a situation where you cannot use the calculator, you can use the formula to calculate the lambing date manually.

$\text {Lambing date} = \text {Mating date} + 147$

So, all you need is the mating date of your sheep, and then you need to find the date, which is 147 days in the future. To make things a bit simpler, this number approximates five months after the mating date. This will give you a rough date to expect the lambing of your sheep.

For instance, if your sheep's mating took place on Christmas eve, you can expect the lambs to be born anywhere between 16th to 26th of May.

## Gestation period of sheep, how long do sheep gestate?

Are you keeping sheep for business, as livestock for their wool, meat, and milk 🥛, or maybe you like them as pets? Maybe as the pet owner or the shepherd, you need to understand all you can about their health and well-being, so knowing what the gestation period of sheep is or how long sheep gestate are a few of the most important things you need to know for the proper care of the ewes in the herd.

The gestation period of sheep is between 142 to 152 days, but 147 days is used as the average to calculate the lambing 🐏 date. The lambing date is the due date of the baby lambs.

## Sheep gestation calendar, how long is a sheep pregnant?

Since the gestation period of the ewe 🐑 is approximately 5 months, they are able to give birth twice a year. Ewes usually give birth to 1-3 lambs but can have as many as 5-6 lambs in some cases.

Once you have realized that your sheep is pregnant, it is important to maintain a lambing and sheep gestation chart. This way, you can keep track of the gestation period of all of the sheep in your herd.

A single ram can be used to mate a flock of ewes. While most sheep have their breeding season in autumn, it can be done in other seasons. When planning to breed your sheep, it is a good idea to maintain a sheep breeding chart, on which you can keep the relevant information of this process. This includes useful contact information, important dates, and any necessary details of the mating. After creating this chart, you may find an additional sheep gestation calendar 📅 comes in handy to organize the herd. On the calendar, you can mark mating dates, predicted lambing dates, and next fertility dates as well as any other important appointments during the gestation period. You may even need to record the date you should start your pregnant sheep on a higher protein diet, which is necessary towards the end of their pregnancy.
