标题：Improving the Quality of the Leaves and Seeds of Rubber Trees ( Hevea brasilliensis ) for Poultry Feed Through Various Types of Microbial Biotechnology
摘要：Objective: This study aims to determine the ability of some microbes to reduce the nutrients and crude fiber from the leaves and seeds of the rubber tree ( Hevea brasilliensis ) at various temperatures after a long fermentation. Methodology: This study was a laboratory experiment to measure the effects of multiple microbial fermentation times and temperatures on the nutrient content of the leaves and seeds of the rubber tree. The design used was a completely randomized 3×3×3 factorial design. The first factor is the type of microbe ( Trichoderma spiralis , Rhizopus oligosporus and Neurospora sitophila ). The second factor is the temperature (24, 34 and 44°C). The third factor is the fermentation time (2, 5 and 8 days). The best of the substrate proximate in the inoculum is then analyzed and calculated to determine the metabolizable energy and protein. Results: The nutrients of the leaves and seeds were compared after processing via rubber processing technology using fermentation with Trichoderma with other treatments and without fermentation. Conclusion: The quality of its nutritional value can be improved, namely, through an increase in the crude protein content of 60.67%, amounting to 32.58% nitrogen retention and 36.67% energy metabolism and a decline in the crude fiber content of 39.02%.
