Abstract

This study aimed to investigate the protective effect of condensed tannins (CT) derived from *Albizia falcataria* leaf extract on soybean meal (SBM) regarding Rumen Degradable Protein (RDP), Rumen Undegradable Protein (RUP), and Crude Protein Degradation (CPD) values. The study employed a Completely Randomized Design (CRD) with four treatments, six replicates, and two experimental units. The treatments were: P0 = no protection, P1 = 2% condensed tannins, P2 = 4% condensed tannins, and P3 = 6% condensed tannins. Protein degradation was evaluated using the ANKOM Daisy Incubator method, with RDP, RUP, and CPD values ​​as the observed parameters. The results showed that protecting SBM with CT from *Albizia falcataria* leaf extract significantly affected (P<0.05) the RDP, RUP, and CPD values. RDP and CPD values ​​decreased as tannin levels increased, whereas RUP values ​​increased. The lowest RDP value (63.48%) and the lowest CPD value (60.76%) were observed in treatment P3, while the highest RUP value (36.52%) was also recorded in the same treatment. The study concludes that the application of condensed tannins from *Albizia falcataria* leaf extract effectively protects SBM protein against ruminal microbial degradation, with the optimal level observed at 6%.
