Dairy Farm

Cheese

Dairy farms produce cheese. Production of cheese begins once you place a dairy farm on oasis grass. Once the worker arrives at the farm, he will sit and wait till three cows have been bred; once that has occured he will procede with milking them. He will then pour the milk into a bucket and wait for it to harden into cheese, which he will then take to the granary (three cheese wheels per trip).

Leather

Dairy farms' secondary use aside from food is leather production. Once you have placed a leather workshop, the tanner will procede to a dairy farm, take a cow back to her workshop, and kill it, then making it into leather armour (provided, of course, that you have a dairy farm and a cow). This cripples cheese production.

Dairy Cow

Cows perform a three-fold purpose in Stronghold. Their main function is in dairy farms, where they produce cheese. They are then led away for slaughter, usually by a tanner for leather armour.

Their final function is to be launched by a Trebuchet at the enemy fortress. If it lands near peasants, especially the campfire, a green cloud will appear. All workers (not soldiers) will sicken and die. Note that apothecaries can provide some resistance to this effect.

Cows can be shot at (and killed) with bows and crossbows and killed by footmen.
