🐐 Goat Gestation Calculator
Estimate the arrival of kids and plan nutrition, vaccinations, and pen preparation around key milestones.
Record the first day of exposure to the buck or AI service.
Gestation Overview
Goat gestation averages 150 days. Twins are common and may arrive a day or two earlier than singles.
How to Use This Calculator
Track breeding
Input when the doe was serviced. If continuous exposure occurred, use the first observed standing heat.
Generate due window
Click to calculate the average due date plus early and late kidding possibilities.
Prepare facilities
Schedule supplemental nutrition, CDT boosters, and kidding pen sanitation ahead of the projected dates.
Formula
Kidding Date ≈ Breeding Date + 150 days
Most does kid within ±3 days of the 150-day average. Litter size, breed, and nutrition can cause slight variations.
Full Description
Coordinating mineral supplementation, vaccinations, and shelter prep around accurate due dates improves kid survival and reduces stress on the herd. This calculator provides a quick reference for herd managers planning seasonal kidding.
Track each doe’s breeding cycle to maintain concise records and evaluate reproductive performance year over year. Consult a veterinarian for pregnancy confirmation and guidance on nutrition for high-producing dairy does.
Frequently Asked Questions
Do meat and dairy breeds have different gestation lengths?
Gestation is similar across goat breeds, though some dairy lines may kid a day earlier. Monitor body condition for clues.
How can I confirm pregnancy?
Ultrasound around 30 days post-breeding or blood tests for pregnancy-associated glycoproteins are reliable.
What vaccinations are recommended pre-kidding?
Many herds administer CDT boosters 4–6 weeks before kidding. Consult your veterinarian for flock-specific protocols.
What if my doe passes the late window?
Some does kid slightly later, especially with single kids. Contact your vet if gestation exceeds 155–156 days or if signs of distress appear.
