Managing a sheep farm requires precision, especially when it comes to breeding and lambing schedules. One of the most critical pieces of information any sheep farmer needs is the expected lambing date. Understanding when your ewes will give birth helps ensure proper preparation for lambing season, improving both lamb survival rates and flock health. To simplify this process, we offer an easy-to-use Lamb Gestation Calculator right on your website.
This powerful yet straightforward tool allows farmers to calculate the expected lambing date based on the breeding date and the chosen gestation length. The default gestation period is set to 147 days—the average length for sheep pregnancy—but it can be adjusted between 140 and 155 days to account for breed variations or environmental factors.
