Milk

Milk is a nutritious liquid food. It not only restores thirst, but also some hunger.

It is obtained from either sheep or cows. To do so, select [#]Extended commands -> [F]ill, and choose the animal in question. It will fill the selected container with milk, and so the most milk you can get at one sitting is 8lbs (from a wooden tub).

Animals can only be milked once a day.
