Abstract：

    This study was designed to develop local grown cassava as replacement feedstuff for corn in poultry feed to reduce the impact of global climate change to the livestock industry and to increase the self-sufficiency of the feedstuff. Cassava from Kaohsiung (K), Yuchin (Y) and Taoyuan (T) were collected and analyzed for their chemical compositions. Cassava from Yuchin was selected for cultivation and for metabolic analysis for poultry. Day one chicks were fed ad libitum until 3 weeks of age then were trained to consume given feed in one hour after feed is given. The metabolic analysis were done at 3, 6 and 13 weeks of age. Results showed that the chemical compositions for K, Y, and T were not different significantly, then the Y cassava was chosen for the growth trial. The chemical compositions of crude protein, crude fat, crude fiber, ash and nitrogen free extract were 2.89%, 1.08%, 1.24%, 4.7% and 90.1%, respectively. True metabolizable energy for broiler chickens was 3628 kcal/kg. In summary, three locations in Taiwan have been found to cultivate cassava, and the analyzed chemical compositions provide some information for the use of cassava as a replacement for corn feedstuff.
