Expert Tip
Sheep gestation averages 147 days (approx. 5 months). Keep ewes in good condition; thin ewes or those with multiples may deliver slightly earlier.

Calculated by adding 147 days to the breeding date. The standard lambing window is 142 to 152 days.
Clinical Considerations
Gestation durations can vary based on animal breed, age, litter size, and genetic factors. If you observe signs of distress or if delivery departs significantly from the calculated date, consult a veterinarian immediately.
