Feeding pellets to livestock is advantageous to both the livestock and its farmer as it supplies the required nutrients to the livestock and is also economical. However, livestock feed pelleting equipment are known to be expensive and unaffordable particularly to the local farmer. A prototype of the pelleting machine was designed and developed for affordability. The machine was also tested to evaluate its performance. The machine consisted of a screw conveyor, die, barrel and hopper. It can be driven by an electric motor or a prime mover. The machine was tested with broiler’s mash and at different levels of moisture content using 500, 750 and 1000 cm^3 each of water and starch binder as preconditioners. The best pellets were formed using 750 cm^3 of either starch or water. The average specific energy consumption when 750 cm^3 of starch binder was used was 0.69 kWh/kg while it was 0.93 kWh/kg when water was used as preconditioner. The density of the pellets varied between 0.7 and 1 g/cm^3. This machine can be manufactured at a local machine shop for small-scale livestock farmers in developing countries.
