When a baby animal no longer drinks its mother's milk and starts to eat other food.
Speaning is a natural part of growing up for baby animals.
Examples:
The baby cow was speaned and started eating grass.
The mother cat speaned her kittens when they were old enough.
The speaned puppies were eating from a bowl.
The speaned piglets were snacking on some apples.
The speaned ducklings were pecking at the ground for food.
The speaned lambs were munching on some hay.
