Donkeys carry their foals for a very long time – longer than many horses. The gestation period averages around 12 months, but varies significantly from animal to animal.
Why the gestation period varies so widely
The duration depends on several factors, including the individual mare, the breed, and the time of year. This is why the due date for a donkey can only be roughly predicted. Many owners pay particularly close attention to their mares in the final weeks.
Signs of approaching birth
- the udder becomes noticeably larger
- waxy droplets may form on the teats
- the mare becomes restless or separates herself from the herd
Donkeys often give birth at night and in quiet conditions. If you are unsure or experience complications, your veterinarian is the right person to contact.
After birth
The foal usually stands up within the first few hours and begins to suckle. You can read more about this period in the article Donkey Foals: The First Few Weeks.
What this has to do with donkey milk
A donkey mare only produces milk after she has given birth to a foal. With a gestation period of around one year, a mare can give birth to at most about one foal per year. The milk belongs to the foal first; only a portion is taken. This is one of the reasons why donkey milk is so rare.
