Roughly one-third of Iran’s total surface area is suited for farmland, but because of poor soil and lack of adequate water distribution in many areas, most of it is not under cultivation.
Of the Iran country’s livestock, sheep are by far the most numerous, followed by goats, cattle, donkeys, horses, water buffalo, and mules.
The raising of poultry for eggs and meat is prevalent. One area where production infrastructure has progressed rapidly is the poultry sector. The face of the industry has now been transformed dramatically so that the entire supply chain process can take place domestically. Iran has also a large dairy industry and imported close to two million tones of feed grain annually in 2006. The raising of pigs is forbidden in Iran due to Islamic law.
