From: | To: |
The average gestation period for sheep is approximately 147 days (about 5 months). This calculator helps predict the lambing date based on the known breeding date.
The calculator uses the standard sheep gestation formula:
Where:
Explanation: The calculation adds 147 days to the breeding date to estimate when lambs will be born.
Details: Knowing the expected lambing date helps farmers prepare for birthing, schedule veterinary care, and plan nutritional management for pregnant ewes.
Tips: Enter the exact breeding date to get the most accurate prediction. The calculator accounts for different month lengths and leap years.
Q1: Is 147 days exact for all sheep?
A: While 147 days is the average, gestation can range from 144 to 151 days depending on breed, nutrition, and other factors.
Q2: Can I use this for multiple births?
A: Yes, though ewes carrying multiples may lamb 1-2 days earlier than those with single lambs.
Q3: When should I prepare for lambing?
A: Begin preparations about 142 days after breeding, as some ewes may lamb early.
Q4: Does season affect gestation length?
A: Slightly - ewes bred in spring may have slightly shorter gestation than those bred in fall.
Q5: What if my ewe goes past the due date?
A: Consult a veterinarian if lambing hasn't occurred by day 150, as prolonged gestation can indicate problems.
