A more thorough explanation:

AGISTER

An agister is a person who takes and pastures grazing animals for a fee. They are engaged in the business of agistment, which means providing land for animals to graze on.

An agister is like a caretaker for animals. They take care of the animals and make sure they have enough food and water. In return, the owner of the animals pays the agister a fee for their services.

For example, a farmer may hire an agister to take care of their cows during the winter months when there is not enough grass in the fields. The agister would provide a place for the cows to graze and make sure they have enough food and water.

Another example would be a horse owner who needs to go on vacation. They may hire an agister to take care of their horse while they are away. The agister would provide a place for the horse to graze and make sure it is fed and watered.
