摘要
对芭蕉芋渣进行了氨化和发酵处理,评价了不同处理芭蕉芋渣作为猪饲料的饲用价值。结果表明:氨化处理提高了芭蕉芋渣总氮含量,粗纤维由22.32%下降为13.71%;发酵处理芭蕉芋渣粗蛋白含量由2.91%增加至15.36%,粗纤维含量由22.32%下降为11.53%。育肥猪对芭蕉芋渣的消化率很低,干物质的消化率为11.27%,粗蛋白消化率为30.23%,粗纤维消化率仅为6.09%;氨化处理芭蕉芋渣干物质消化率提高11.45%,粗纤维消化率提高12.48%;发酵处理芭蕉芋渣干物质消化率提高5.99倍,蛋白质消化率提高2.61倍,粗纤维消化率提高6.72倍。
The feeding value of Canna edulis Ker. residue treated with ammoniation and fermentation in pigs was evaluated in this study. The results showed that the total nitrogen content of Canna edulis Ker. residue was increased by ammoniation treatment, and the crude fiber decreased from 22.32% to 13.71%; the crude protein content was increased from 2.91% to 15.36% with the treatment of fermentation, and the crude fiber content decreased from 22.32% to 11.53%. The digestibility of fattening pigs against Canna edulis Ker. residue was relatively low, the dry matter apparent digestion rate was 11.27%, the crude protein digestion rate was 30.23%, and the crude fiber digestion rate was 6.09%. After treatment of ammoniation, the dry matter digestibility increased by 11.45%, and crude fiber digestibility increased by 12.48%; the dry matter digestibility increased 5.99 times, the protein digestibility increased 2.61 times, and the crude fiber digestion rate increased 6.72 times by fermentation treatment.
