As grass grows in abundance, these areas serve as pasture lands for cattle. From cattle, milk, butter, ghee, and meat are obtained, the main food for most people. The profession of cattle roaring is mostly adopted in hot and temperate climate regions. Farms are made in different regions where cattle are bred in large quantities. These farms are near the cities or the industrial centres, so the market is available to sell milk, meats, butter etc. In areas with water-storage facilities but with extreme climates. Cattle rearing is not done permanently, and people bring their cattle to those areas during butter seasons. They migrate immediately when there is a climate change.
