URL: https://gestationcalculators.com/goat-calculator
Goat farming, whether for dairy, meat, or fiber, starts with well-managed breeding. The Goat Gestation Calculator helps predict your doe’s kidding date accurately — allowing you to prepare for healthy deliveries and higher survival rates.
This comprehensive guide covers gestation lengths by breed, pregnancy signs, nutrition, kidding prep, and newborn care for your herd.
📅 How Long is a Goat Pregnant?
Goats are typically pregnant for 145 to 155 days, with 150 days being the average. Breed, age, litter size, and seasonal factors can slightly influence this.
| Goat Breed | Average Gestation |
|---|---|
| Nubian | 150 days |
| Alpine | 150 days |
| Boer | 148–152 days |
| Nigerian Dwarf | 145–150 days |
| Kiko | 147–155 days |
📘 Cornell University Small Ruminant Program supports that age and multiple fetuses may shorten gestation by 1–3 days.

📊 Goat Breeding vs. Kidding Chart
Use this monthly guide to plan breeding for optimal kidding windows:
| Breeding Month | Expected Kidding |
|---|---|
| August | January |
| September | February |
| October | March |
| November | April |
| December | May |
| January | June |
| February | July |
📌 Many breeders aim for early spring births (February–April) to avoid harsh winter conditions.
🐐 Pregnancy Stages in Goats (Month-by-Month Breakdown)
| Month | Fetal Development & Doe Changes |
|---|---|
| 1 | Fertilization; embryo implants by day 18–20 |
| 2 | Organ formation begins; early signs appear |
| 3 | Fetus starts to grow rapidly; uterus expands |
| 4 | Hair growth, skeletal development, and weight gain |
| 5 | Final fetal development; udder fills with colostrum |
Ultrasound pregnancy confirmation is possible by day 30, though more accurate by day 45.
📘 Washington State University Extension has an excellent guide on reproductive management for goats.
🧪 Signs of Pregnancy in Goats
You may notice the following after 3–4 weeks of successful breeding:
- No return to estrus (heat) within 18–21 days
- Increased appetite or mild lethargy
- Fuller abdomen after 8 weeks
- Udder development (especially in last 3 weeks)
- Changes in temperament (more affectionate or quiet)
💡 A blood pregnancy test (BioPRYN) is accurate by day 28 and useful for early detection.
🚼 Kidding Signs: Preparing for Goat Birth
Goats usually give birth quickly once labor starts. Expect signs around day 145–150:
- Vulva softens and swells
- Ligaments near the tail loosen
- Doe becomes restless or separates from herd
- Mucous discharge and pawing/nesting
- Udder fills with milk (last 1–2 weeks)
- Temperature drop below 100°F in final 12–24 hours
🧠 According to UC Davis Goat Extension, proper kidding preparation reduces complications by over 50%.
🛠️ Doe Management Tips
🥗 Nutrition
- Early pregnancy: High-quality hay and minerals
- Mid-pregnancy: Increase protein and maintain energy
- Final month: Add grain slowly; ensure free-choice minerals
- Post-kidding: Introduce alfalfa, grain, and water immediately after birth
🧼 Housing
- Prepare kidding stalls with clean bedding
- Sanitize areas and provide warmth (especially in winter)
- Use a heat lamp safely if temperatures drop below freezing
💉 Health
- Deworm does 2 weeks before kidding (vet-guided)
- Vaccinate for CD&T and BoSe 2–4 weeks before birth
- Trim hooves prior to kidding for comfort and hygiene
🐐 Newborn Kid Care
After birth, immediate care includes:
- Clear airway and dry off with a towel
- Dip umbilical cord in iodine
- Ensure colostrum intake within 1–2 hours
- Check for proper latching and nursing
- Monitor temperature, movement, and breathing
Twins and triplets are common — be prepared with colostrum replacer in case of large litters or weak kids.
❓ Goat Pregnancy FAQs
