The Effect of Soybean Meal and Organic Micro Minerals (Zn and Cr) Supplementation on the Digestibility of Dry Matter, Organic Matter, Crude Protein, and Crude Fiber in Rambon Male Goats 1Study Program of Doctoral Postgraduate, Faculty of Agriculture, University of Lampung, Jl. Soemantri Brodjonegoro No. 1, Bandar Lampung, 35145, Indonesia Abstract This study aims to determine the effect of soybean meal (SBM) and organic minerals (Zn and Cr) supplementation in rations on the digestibility of crude protein, crude fiber, dry matter, and organic matter in male Rambon goats from November 2022 to January 2023 at Teaching Farm and Laboratory of Animal Nutrition and Feed, Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. The experimental design used was a randomized block design with 4 treatments and 3 replications, involving 12 male Rambon goats. The treatments were as follows: P1: 100% basal ration (silage of cassava leaves, cassava, palm oil cake, and urea)- P2: 90% basal ration + 10% SBM- P3: 100% basal ration + 40 ppm Zn and 0.3 ppm Cr- P4: 90% basal ration + 10% SBM + 40 ppm Zn and 0.3 ppm Cr. Data were analyzed using ANOVA followed by the LSD test at the 5% level. The conclusions of this study showed that 1) there was a significant effect (P<0.05) on the digestibility of crude protein (P3, 78.40%) and crude fiber (P4, 69.79%)- and 2) there was no significant effect (P>0.05) on the digestibility of dry matter and organic matter.
