How to Use the Goat Gestation Calculator
- Enter the date your doe was bred or exposed to a buck.
- The calculator computes the expected kidding date based on 150-day caprine gestation.
- Review the current gestation day and days remaining until kidding.
- Check the developmental stage to understand fetal growth milestones.
- Plan feeding and housing adjustments based on the gestation timeline.
The Formula
Variable Definitions
- Gestation: The period from conception to birth, averaging 150 days in goats
- Kidding: The process of giving birth in goats
- Doe: A female goat
- Buck: A male goat (also called a billie)
- Kid: A baby goat
Calculating Kidding Date from February Breeding
Find the kidding date for a doe bred on February 10, 2026.
- Step 1: Identify the breeding date: February 10, 2026.
- Step 2: Add 150 days gestation period to the breeding date.
- Step 3: Days remaining in February: 28 - 10 = 18 days. 150 - 18 = 132 days remaining.
- Step 4: Mar(31) + Apr(30) + May(31) = 92 days. 132 - 92 = 40 days. Jun(30). 40 - 30 = 10 days.
- Step 5: The estimated kidding date is July 10, 2026.

Frequently Asked Questions
How long is a goat pregnant in days?
A goat is pregnant for approximately 150 days (about 5 months). The normal range is 145 to 155 days. Breed can influence gestation — dairy breeds like Saanen average 150 days, while some Nigerian Dwarf goats may kid at 145 days.
How can I tell if my goat is pregnant?
Signs include: refusal to re-breed at the next heat cycle, belly enlargement after month 3, udder development 2-4 weeks before kidding, weight gain, and increased appetite. Ultrasound can confirm pregnancy at day 28-30.
How many kids will my goat have?
Dairy breeds typically have 2-3 kids per pregnancy. Meat breeds may have 1-2. First-time does (yearlings) often have single births. Nigerian Dwarf goats frequently have 3-4 kids. Some breeds can have up to 5 kids.
When should I increase feed for a pregnant doe?
Maintain normal feeding through the first two trimesters. Increase feed by 20-30% in the last 6 weeks (Trimester 3). In the final 2 weeks, increase to 30-50% above maintenance. Switch to higher protein and calcium feeds as kidding approaches.
What are signs of approaching labor in goats?
Signs include: udder filling and becoming tight 2-4 weeks before kidding, ligaments around the tail head loosening 1-2 weeks before, isolation from the herd, restlessness, and pawing at the ground. Active labor begins with visible contractions.
How long does kidding take?
Normal kidding takes 30-60 minutes from the time active contractions begin. If no progress is made after 45-60 minutes, or if only one foot or head is visible, this may indicate a malpresentation and requires immediate veterinary attention.
What should I do if a kid is stuck?
If you cannot deliver a kid within 30-45 minutes of active pushing, call your veterinarian immediately. In an emergency, clean your hands and arms thoroughly, apply lubricant, and gently reposition the kid. Do not pull forcefully — this can injure both mother and kid.
Can goats have kids year-round?
Goats are seasonal breeders that typically cycle in fall (September-December) for winter/spring kidding. However, many commercial operations use lighting programs or buck exposure to control breeding timing. Consult your vet about optimal breeding schedules for your climate.
