Guinea Pig Gestation Formula
- Total Gestation Period: 59-72 days
- Male Separation: Mating Date + 14 days
- Nesting Preparation: Due Date – 7 days
- Weaning Period: Birth Date + 21 days
Parameters
- Mating Date: The starting date of pregnancy
- Minimum Gestation: 59 days
- Maximum Gestation: 72 days
- Separation Period: 14 days after mating
- Nesting Setup: 7 days before due date
- Weaning Duration: 21 days after birth
For mating date January 1:
- Male Separation: January 15 (1 + 14 days)
- Nesting Date: February 24 (March 1 – 7 days)
- Due Date Range: March 1-14 (59-72 days)
- Weaning Date: April 4 (March 14 + 21 days)
How to Calculate Guinea Pig Gestation?
- Start with the mating date
- Add 14 days to determine male separation
- Add 59-72 days to estimate due date range
- Subtract 7 days from earliest due date for nesting preparation
- Add 21 days to birth date for weaning timeline
If mating occurred on January 1st:
Check male separation needed by January 15th, Prepare nesting area by February 24th, Expect birth between March 1-14th, Plan weaning around April 4th
