The chickpea is part of the Vicieae tribe, the genus Cicer, a genus that includes several spontaneous annual and perennial species. The species Cicer arietinum is cultivated, which is divided into four subspecies: orientale, asiaticum, mediterraneum and euroasiaticum. The subspecies euroasiaticum is particularly important and includes several ecotypes, distinguished by the height of the bush, the color of the flowers and the shape of the bush. Chickpea beans are used in food in different forms, respectively fried, as a substitute for coffee, etc. Like animal feed, the grains (crushed) have more limited uses for horses and pigs. The straws (by-products) have a poor fodder value, because they become lignified and the leaves fall easily. Due to the content of oxalic and malic acid, the green plant is not used in animal feed.
