【摘要】 本研究测定了木薯粉的营养成分含量、消化能和代谢能,结果如下:以干物质计平均含粗蛋白质2.8±0.7％、粗脂肪0.8±0.2％、粗纤维3.0±0.2％、粗灰分2.2±0.6％、无氮浸出物91.2±1.5％、钙0.32±0.16％、磷0.1±0..02％,消化能(猪)为15.07±0.54MJ/kg、代谢能(鸡)为14..23±0.38MJ/kg;每公斤干物质含铁168±49mg、铜9±4mg、锰43±16mg、锌64±13mg。饲养试验结果表明,生长鸡喂饲含15％木薯粉的饲粮,鸡的生长和饲料效率良好,当木薯粉的用量增加到45％时鸡的增重和饲料效率降低。更多还原

【Abstract】 The nutrients, digestible energy (DE) and metabolizable energy (ME) of cassava meal were determined in the study. The results were as follows;The cassava meal contained on the average (DM basis)2. 8±0. 7% crude protein,0. 8±0. 2% ether extract,3. 0±0. 16% ash,91. 2± 1. 5% N-free extract,0. 32±0. 16% calcium,0. 1±0. 02% phosphorus;iron 168±49 mg/kg, copper 9±4 mg/kg,manganese 43±16 mg/kg,zinc 64±13 mg/kg;the DE value was 15. 07± 0. 54 MJ/kg for pigs,and the ME value was 14. 23±0. 38 MJ/kg for chickens. Feeding experiments indicated that the growth rate and feed conversion efficiency were acceptable when growing chickens were fed diets containing 15% cassava meal,but the weight gain and feed conversion efficiency of chickens decreased as the level of cassava meal increased to 45% in the diet.更多还原
