Sago starch is a useful resource for foodstuffs and indstrial raw materials. With the increasing production of sago starch, very large amounts of fibrous residue have been discharged from sag mills. For the further development of sago starch production, it is necessary to find the use for the residue. In the research project, I have conducted the fundamental research for production of feed from fibrous residue in consideration of its character.1. Ammoniation : The fibrous residue was treated with 3% ammonia, 70% moisture at 25℃ and 30℃ for 6 weeks in a glass bottle fitted with a Bunsen gas release valve. It gave similar results between the treatment of 25℃ and 30℃. Putreification of residue was prevented and the total nitrogen content became 3.2% by the reaction of ammonia with fiber. The residual starch decreased as much as 15%. But digestibility was improved.2. Silage preparation : The fibrous residue was treated with 70% moisture at 25℃ and 30℃ for 6 weeks in a glass bottle fitted with a Bunsen gas release valve. It gave similar results between the treatment of 25℃ and 30℃. The pH dropped less than 4.0 by the resulting lactic acid. Although the residual starch decreased as much as 30%, the quality of the silage seemed to be very good.3.Urea-treated fermentation : The fibrous residue was treated with 6% urea, 70% moisture, and 0.5% rice bran or soybean plant at 30℃ for 8 weeks. The urea was degraded to give ammonia by urease producing microorganism. The urea content became about 2% after two weeks. In the first stage, pH raised to 8.0 and then fall to 6.8. Putreifiration of residue was prevented by this fermentation. But digestibility was not improved.3. Solid-state fermentation : Chalara paradoxa and Trichoderma viride were cultivated on the residue moistured with Czapek nutrient under unsterilized condition at 30℃. The growth of these fungi was poor and the increase of total nitrogen was not achieved.

Sago Starch是一种有用的食物，并从SAG磨坊中排出了Sago淀粉残留物的生产，以进一步开发Sago淀粉的生产研究项目，我构成了CHS Aracter中的Fiduus残留物生产的饲料。1。 BUNSEN气体释放阀可预防残留物，并且氨与纤维的反应变为3.2％。装有Bunsen气体释放阀的瓶子在25°C的处理之间给出了相似的结果。pH值降低了4.0次，降低了30％。尿液处理的发酵液用6％的尿素处理，大米麸皮或大豆植物30°C进行脱脂以通过产生尿素的微生物来提供氨水。然后，phend降至6.8总氮的总数没有疼痛。
