Abstract : This study aims to determine and compare the fiber quality of various genotypes of sorghum grown in Bogor, West Java, Indonesia. Samurai 1, Samurai 2, Pahat and Patir 3.7 are varieties of sorghum which are projected as special varieties of sorghum for bioethanol and food, but can also be used as animal feed in Indonesia. While Patir 37 is a special sorghum for feed. This study aims to determine the fiber profile of four varieties of sorghum used as ruminant feed. This study was arranged in a completely randomized design. The factors studied were four types of sorghum. The variables measured were fiber composition: NDF, ADF, Cellulose and lignin (%). The results showed that BMR Patir 37 sorghum had the lowest NDF(50.62), ADF(30.09), Cellulose (27.35) and Lignin (2.56) (P<0.01) content compared to the Samurai variety. 1. (63.40; 41.02; 36.72; 3.95). Samurai 2 (52.79; 35.51; 31.27; 3.98) and Chisel (67.24; 45.37; 39.59; 4.99). Based on these findings, the sorghum cultivar Patir 37 had the lowest fiber profile.
