This research aims at figuring out the digestibility value of the weaning tup Garut with rations Calliandra calothyrsus, Indigofera sp., and mixture as a concentrate substitution (in vivo). Six treatment of experimental rations were tested consisting of P0 (70% P. purpureum cv. Mott+ 30% Concentrate), P1 (70% P. purpureum cv. Mott+ 15% Concentrate+ 15% C. calothyrsus), P2 (70% P. purpureum cv. Mott+ 15% Concentrate+ 15% Indigofera sp.), P3 (70% P. purpureum cv. Mott+ 30% C. calothyrsus), P4 (70% P. purpureum cv. Mott+ 30% Indigofera sp.), dan P5 (70% P. purpureum cv. Mott+ 15% C. calothyrsus+ 15% Indigofera sp.). The method used was Completely Randomized Design (CRD) with four replications, while the observed variables were dry matter digestibility, organic matter digestibility, and crude protein digestibility. The results show that there is an effect of treatment (P< 0.05) on the ration digestibility value. It can be concluded that the concentrate substitution using 15% Calliandra calothyrsus and 15% Indigofera sp. results in the best ration digestibility, namely 77.10% dry matter digestibility, 77.65% organic matter digestibility, and 71.48% crude protein digestibility.
