Goat Pregnancy Calculator Formula
Estimated Kidding Date = Breeding Date + Gestation Period
Formula Source: Merck Veterinary Manual, American Goat Society.
Variables:
- Breeding Date: The day the doe was successfully bred.
- Gestation Period: The number of days a doe is pregnant (typically 145 to 155 days).
- Kidding Date: The expected day the goat will give birth.
What is a Goat Pregnancy Calculator?
A Goat Pregnancy Calculator (or Gestation Calculator) is a digital tool designed to help goat breeders determine the expected due date of their does. Knowing the approximate “kidding” date is crucial for managing nutrition, preparing the birthing area, and monitoring for potential complications.
Standard goat gestation is roughly 150 days. However, factors like the breed, age of the doe, and the number of kids (twins or triplets) can slightly shift this timeline. Small breeds like Nigerian Dwarfs often have shorter gestation periods than larger dairy breeds like Saanens.
How to Calculate Goat Pregnancy (Example)
- Identify the Breeding Date: For example, January 1st.
- Define Gestation Days: Use the standard 150 days.
- Add Days to Date: Adding 150 days to Jan 1st results in May 31st.
- Account for Range: A healthy birth can occur between May 26th and June 5th (145-155 days).

Frequently Asked Questions (FAQ)
How long is a goat pregnant? The average pregnancy for a goat is 150 days, but it can range from 145 to 155 days.
What are the signs of kidding? Signs include a full udder, nesting behavior, discharge, and “sinking” around the tail head.
Do different breeds have different gestation lengths? Generally, yes. Miniature breeds tend to kid a few days earlier than standard breeds.
Can I use this for sheep? Sheep have a very similar gestation (approx. 147 days), but it’s best to use a species-specific calculator for accuracy.
