Agricultural Innovation Studies for Coping with Climate Change and Food Security
本研究乃針對近年來全球氣候變遷造成之穀物減產與畜禽飼料成本增加的威脅，開發台灣自產之樹薯，並改善樹薯在家禽的利用效率，以達到增加飼料自給率的目的，穩定國內畜產業的發展。本研究蒐集桃園、台南及高雄三地生產之樹薯進行營養成分分析及比較，並以台南玉井種植之樹薯，進行肉雞之代謝試驗。於雞隻飼養至3週齡開始每日訓練其飼料於1小時內採食完畢，於4、6及13週齡各進行一次代謝試驗。分析結果三地區之營養成分差異不大，因台南玉井所種植之樹薯數量較大，可供未來飼料化之應用，選擇玉井地區之樹薯繼續種植。其營養成分以乾基表示，分別為：粗蛋白質：2.89%、粗脂肪：1.08%、粗纖維：1.24%、灰分： 4.7%、無氮抽出物： 90.1%。代謝試驗結果顯示樹薯於白色肉雞之真代謝能為3628kcal/kg。綜言之，本研究初步確定台灣目前仍有種植樹薯，而其營養成分及家禽代謝能皆適合發展樹薯飼料化成為替代進口玉米之飼料原料。
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.
