Twelve male Crossbred goats were assigned to three dietary treatments in a completely randomized design, treatments were comprised of replacement of soybean meal with CPMSG at 0 (control), 10 and 15% in concentrate. Animals were receiving concentrate at 2.0% of BW while pangola hay was offered ad libitum basis. BW gain, ADG and CP digestibility were significantly higher (P<0.05), in 15% CPMSG diet. Ruminal NH3-N concentration was the highest (P<0.05) in CPMSG 15% treatment, total VFA concentrations were higher in CPMSG treatments (10 and 15%) than control treatment, whereas ruminal microorganism populations were similar among treatments. It could be concluded that using CPMSG can replace 15% protein source in goat concentrate diets with increased feed intake, CP digestibility, total VFA concentrations and growth performance.
