Pig Farms were used by the Horde during the Second War. Just before the Third War, when Thrall went to Kalimdor, he left behind the pig farms and instead used burrows. After the war, Thrall's forces continue to use both pig farms and burrows.
In Warcraft II
[Pig] Farms provide the necessary raw foodstuffs to sustain both the slave labor force and the war parties in the field. Without a sufficient food supply, new units cannot be acquired. The staple diet of the Orcs - along with their kindred Troll and Ogre brothers - is fresh meat. To satisfy this hunger for flesh, wild Boars are trapped and bred for food. Readily abundant in most regions, they have become a bonfire favorite (along with a tankard of Bloodmead) among the hardened troops engaged in a long war march.
In Warcraft III
Also, during the Third War, the Blackrock clan used pig farms to fed their troops. Some were destroyed by Arthas' forces when they attacked the Blackrock clan village during The Scourge of Lordaeron and the rest of them were destroyed by the Scourge during Path of the Damned as they intended to communicate with Archimonde using a functional gate located in the Blackrock clan village.
