In nutritional experiments the animals are kept in metabolic cage and are fed according to the planned interval times. A machine was designed and fabricated to feed the sheep every one or two hours. The machine operates with 220 Volts electricity and the feed storing capacity is designed for three days feeding. The weight of sheep and type of feed determines the amount of feed required. By changing the volume of cylindrical measuring bucket, it is possible to supply the required feed. The machine is smaller in size, accurate in supplying feed and more economical than the commercial types such as tranporting belt and automatic feeding container.
