his study aims to evaluate the quality of thr complete feed silage fiber fraction of ruminants. This research lasted for 3 months from July-September 2020 at the Kupang State Agricultural Polytechnic Campus. This study used a completely randomized design (CRD) with 4 treatments and 5 replications. The treatments consisted of LP9: 9 weeks of storage, LP6: 6 weeks of storage, 3 of 3 weeks of storage and 0 of 0 weeks of storage. Variables observed: ADF, NDF, Cellulose, Hemicellulose and Lignin. Analysis of variance showed that the storage time for complete feed silage had a significant effect on (P <0.05) the content of ADF, NDF, Cellulose, Hemicellulose and Lignin. Conclusion: The storage time for complete feed silage increased in NDF and ADF levels, while cellulose, hemicellulose and lignin decreased with increasing storage time.
