poultry. A good knowledge of the nutritional value of such plants in poultry nutrition would be valuable since they grow relatively easy with relatively simple agronomic practices that does not require much labour and cost hence this study. Centrosema pubensce leaves, with nutrient content of: dry matter 23.3%, crude fibre 30.8%, crude extract 3.9%, crude protein 21% and total digestible nutrient 4.9% are commonly found in the tropics. Being a leguminous plant, it can be used as livestock feed addictive. The abundance of these succulent leguminous plants around homestead and villages that contain reasonable levels of certain valuable nutrients appears not to have been fully explored. It is believed that the use of such locally abundant green leaves as feed supplements without doubt can improve the performance of poultry birds through enhanced growth. A good knowledge of the nutritional value of such leaves that grows relatively easy will help farmers to accomplish this goal. The objective of this experiment is therefore to evaluate the effects of Centrosema pubensce leaves and its extract as a supplementary feed on the performance of broilers.
