Goat Pregnancy Calculator
Plan for your goat's pregnancy with precision
Calculate when your goat is due to give birth with this caprine pregnancy calculator. Enter the date of breeding below and you will be given expected pregnancy dates so you can prepare for kidding.
Expected Due Dates:
The estimated due date is 150 days from breeding, which is the length of gestation in goats. The expected dates indicate the earliest and latest expected dates of delivery. Dates may vary in some instances.

Goat Pregnancy Calculator
Estimate your goat’s due date accurately by entering the mating date.
Goats typically have a gestation period of 145–155 days. This tool is designed to help farmers, breeders, and homesteaders track key pregnancy milestones, plan for kidding (the term for goat birthing), and ensure optimal prenatal care.
Important: For best results and health outcomes, always confirm pregnancy status and timing with a qualified veterinarian.
How to Use the Goat Pregnancy Calculator
Using the goat pregnancy calculator is fast and straightforward. You only need one key detail: the date your doe (female goat) was bred.
Steps to follow:
-
Select the mating date:
Choose the specific date your goat was bred.-
If multiple matings occurred, use the earliest date.
-
Keep detailed breeding records to avoid confusion.
-
-
Click “Calculate Due Date”:
The tool will estimate the expected kidding window, usually between 145–155 days later. -
Review the pregnancy timeline:
You’ll get a clear breakdown of fetal development, trimester changes, and the estimated kidding date.
Tip: Use this calculator alongside veterinary checkups and ultrasounds (if available) to monitor fetal health and development.
What Is the Average Goat Gestation Period?
The typical goat gestation period ranges from 145 to 155 days, depending on breed, age, and whether it’s a single or multiple-kid pregnancy.
| Breed Size | Average Gestation |
|---|---|
| Dwarf breeds | 145–150 days |
| Medium/Standard breeds | 147–152 days |
| Large breeds | 150–155 days |
Note: Shorter gestations may occur in twins or triplets. Overdue pregnancies should be checked by a vet.
What Is the Goat Pregnancy Timeline?
Goat pregnancies follow predictable stages. Each period is associated with specific changes in both the doe and the developing kids.
| Stage | Days | Description |
|---|---|---|
| Fertilization | Day 0 | Ovum fertilized in fallopian tubes |
| Embryo Implantation | Days 15–19 | Embryos embed into uterine lining |
| Organ Development | Days 30–60 | Organs and skeletal systems begin forming |
| Visible Changes | Days 60–90 | Udder development, weight gain, belly expansion |
| Rapid Fetal Growth | Days 90–135 | Fetuses grow quickly; appetite may increase |
| Kidding Preparation | Days 135–155 | Nesting, restlessness, udder full, vulva swelling |
Veterinary Tip: By Day 45–60, vets can often confirm pregnancy via palpation or ultrasound.
Do Different Goat Breeds Have Different Pregnancy Lengths?
Yes — just like with cats and dogs, goat gestation length can vary by breed.
| Breed | Gestation Range |
|---|---|
| Nigerian Dwarf | 145–150 days |
| Boer Goat | 148–152 days |
| Alpine | 150–155 days |
| Nubian | 150–155 days |
| Saanen | 147–153 days |
Insight:
Smaller goats (like Nigerian Dwarfs) may kid earlier, while large breeds (like Nubians or Alpines) often reach the 155-day mark. If gestation goes beyond 155 days, veterinary intervention may be needed.
What Are the Signs of Pregnancy in Goats?
Goats exhibit clear physical and behavioral changes around weeks 4–5 of pregnancy. However, signs can vary by individual.
Physical Signs:
-
Slight weight gain and rounded belly
-
Udder development (often from day 90 onward)
-
“Springing” (vulva swelling) near due date
-
Decrease in milk (in previously lactating does)
Behavioral Signs:
-
Reduced interest in bucks
-
More docile or reserved temperament
-
Nesting behavior or increased lying down late in gestation
-
Restlessness just before kidding
Note: Goats are prey animals and may mask discomfort. Always monitor for subtle changes.
How to Prepare for Goat Kidding at Home
Proper preparation ensures a smoother kidding process and protects both doe and kids from complications.
1. Set up a kidding area:
-
Choose a clean, dry, draft-free pen with good bedding (e.g., straw).
-
Isolate the doe from the herd about a week before the due date.
-
Keep the space quiet and stress-free.
2. Prepare supplies:
-
Clean towels
-
Iodine or antiseptic for umbilical cords
-
Lubricant (in case of stuck kids)
-
Gloves and sanitizer
-
Flashlight or headlamp
-
Vet’s number on standby
3. Monitor closely:
-
Check every few hours in the final week.
-
Look for pacing, talking (bleating), mucus discharge, and tail raising.
-
Most does deliver within 2–4 hours once active labor begins.
4. Post-birth care:
-
Ensure each kid starts nursing within 1–2 hours.
-
Dip navels in iodine.
-
Provide warm shelter and clean bedding.
-
Check that the placenta is expelled fully within 12 hours.
When Should You Visit the Vet During Goat Pregnancy?
Veterinary visits offer peace of mind and early intervention when needed.
| Timeframe | Purpose |
|---|---|
| Days 30–45 | Pregnancy confirmation (ultrasound) |
| Day 60+ | Monitor fetal health, check for twins |
| Final week | Ensure readiness for safe delivery |
| Post-kidding | Check for retained placenta or weak kids |
Urgent Vet Signs:
-
Bleeding before labor
-
Straining with no kid delivery after 1 hour
-
Weak, unresponsive kids
-
Doe refuses to eat or appears disoriented

Frequently Asked Questions
Can goats have false pregnancies?
Yes. Pseudopregnancy is common in goats and involves fluid buildup without actual fetal development. A vet can confirm real pregnancy via ultrasound or blood test.
How many kids do goats usually have?
Most goats deliver 1 to 3 kids, with twins being most common. Some breeds, like Nigerian Dwarfs, often have triplets.
Should I feed differently during pregnancy?
Yes. Provide a balanced diet rich in energy, protein, and minerals — especially calcium and selenium. Late pregnancy requires more nutrients for fetal growth.
My goat is past 155 days. What should I do?
Contact a vet. Goats rarely go much past 155 days unless the due date is miscalculated. Delay may indicate complications.
Can I breed my goat again right after kidding?
It’s best to allow at least 3–4 months for full recovery before rebreeding. Early breeding can stress the doe and reduce kid health.
