93        The design of a feed mill depends on the intended production capacity. For a small scale feed mill (20-50 kg feed production per day), a total area of around 3000 sq. ft will be sufficient, while medium and large feed mills require more area. The major components of a feed mill are (i) Building and (ii) Equipment/ Machinery   (i) Building   The building should preferably be of concrete provided with for pest and rodent proof facility, with proper accessibility to road and electricity. For small and medium scale feed mills, the ingredient receiving and storage area can also be integrated with in the main building. For large scale mills, the ingredient storage facility should be kept separately.   (ii) Equipment/ Machinery  The major essential equipment/ machinery required for a feed mill and their purpose are listed in the following table.
