It is desirable that donkeys are registered, regardless of whether they are young or old.
Note that you do not need to know breeding details, and the animal can be any age at registration.
By registering stock you gain several benefits.
Registration can prevent unintentional inbreeding now or in the future, give your donkey an identity, and add to the value of your stock.
