“…Proteolysis inhibition occurs because phenolic compounds cover protein surface, therefore it obstructs enzyme and substrate interaction (Anantasook et al, 2013). Condensed tannin form 1 g Leucaena leaves can bind 26.25 g protein bovine serum albumin (Rimbawanto et al, 2015).…”

The objectives of the research were to supply nitrogen for protein synthesis of ruminal microbe from slow release urea and to supply post-rumen protein from soybean meal protected with condensed tannin (CT) from crude Leucaena leaves extract. In Experiment 1, slow release urea (SRU) was made by extrusion of cassava waste-urea, tapioca meal-urea and cassava meal-urea. Evaluation of SRU properties was based on residual nitrogen concentration and ruminal fermentation products (total volatile fatty acid and ammonia-nitrogen) in vitro. In Experiment 2, soybean meal protected with CT from crude Leucaena leaves extract as much as 1,68 g tannin/100 g DM soybean meal. SRU that was selected from Experiment 1 was used as the supplement in sheep ration whose protein source was protected with CT. SRU supplement in basal rations was 0, 6.36, 12.75, 19.11% DM. In vitro result in Experiment 1, showed that SRU of cassava waste, tapioca meal and cassava meal were different (P<0,01) on residual nitrogen content, total VFA, ammonia-N, and fermentation time. The optimum SRU obtained from cassava waste by inhibiting nitrogen hydrolysis up to 14 h. In Experiment 2, SRU supplementation of cassava waste on basal ration whose protein source was protected with CT increased dry matter (DM) degradability (P<0,01), total VFA (P<0,01), ammonia-N (P<0,01), and did not affect crude protein (CP) ruminal degradation. Post-ruminal degradability of DM and CP increased (P<0.01) in line with the increasing supplement, and reached the optimum level at 12,75 – 19,11% DM. In conclusion, cassava waste was a potent SRU through extrusion process and could be harnessed as SRU supplement in ration with protein source protected with condensed tannin to improve ruminal microbe protein synthesis.

“…From Table 2, it can be seen that the CP content of L. leucocephala was ranged from 18.32 to 21.38%. The CP content is lower than other research on L. leucocephala which ranged from 22.16% to 31.8% (Aregheore, 2002;Edward et al, 2012;Soltan et al, 2012;Rimbawanto et al, 2015). The different CP content is allegedly due to the different biomass on leaves and branches fraction.…”

Farmers in Kupang had 3 different Leucaena leucocephala plantations with each was planted under different local planting methods as their forage resource. In this research, we evaluate the production, nutritional content and in vitro digestibility of the L. leucocephala in all of the plantations during the early and late dry season as well as during rainy season. The first plantation was planted under Amarasi model (Amarasi plantation), where the L. leucocephala were planted in array; the second plantation was planted under Mamar Kering model (Mamar Kering plantation), where the L. leucocephala were planted by the natural fauna of the plantation; and the third plantation was planted under Selobua model (Selobua plantation), where the L. leucocephala were planted intercropping with crops. The harvest was done every four months from March 2016 to April 2017 by also following local harvesting practices (all of the branches and leaves were cut at 2-3 m above ground). The observed variables include dry matter (DM), organic matter (OM), crude protein (CP), neutral-detergent fiber (NDF), and acid detergent fiber (ADF) content, as well as the in vitro DM and OM digestibility of L. leucocephala. All of the obtained data were analyzed with nested ANOVA and followed with LSD test. The results showed that different planting model and season gave differences (P<0.01) to the DM, NDF, ADF, in vitro DM and OM digestibility. The study concluded that the Amarasi plantation had the highest production, while overall nutritional content and in vitro digestibility of L. leucocephala was better during rainy season, and the highest was found in Selobua plantation.

“…The preparation stage includes the extraction of mahogany leaves. Extraction of mahogany leaves was carried out according to Rimbawanto et al (2015) method and determination of total tannin in mahogany leaves based on Makkar (2003). The addition of tannins into soybean meal was done by spraying mahogany leaf extract using a sprayer into soybean meal until homogeneously mixed and then dried at room temperature.…”

“…This has been proven by Cahyani et al (2012) who reported that the protein protection treatment of soybean flour using mangrove leaf tannins was able to reduce fermentability due to the formation of a tanninprotein complex. (Rimbawanto et al 2015) stated that the use of calliandra condensed tannins in trash fish increased total protein digestibility in vitro.…”

The study was aimed to examine effect of protecting soybean meal using mahogany leaf extract on rumen fermentation products in vitro. The material used was cow rumen fluid, basal ration consisting of concentrate and elephant grass with a ratio of 60:40%, and mahogany leaves. The research was carried out in three stages: mahogany extraction, protein protection using mahogany extract, and in vitro stages. The test was conducted in vitro based on a completely randomized design (CRD). The treatments consisted of 4 kinds of soybean meal protection with 0% tannin concentration (T0); 1.5% (T1); 3% (T2); and 4.5% (T3). Data obtained were analyzed by analysis of variance and tested using orthogonal polynomials. Results showed that addition of protected soybean meal with mahogany leaf extract had a cubical effect on partial VFA, methane gas and post-rumen dissolved protein, a quadratic effect on protozoa, and a linear effecton N-NH3, SPM, and RUDP. Giving extra mahogany leaves at a level of 1.5% produced a fermented product that was not different from the control while giving a level of 3% got the highest fermentation product. Giving mahogany leaf extract at a level of 4.5% resulted in the highest SPM, and RUDP but there was a decrease in soluble protein, which indicated the occurrence of overprotection. The addition of 3% mahogany leaf extract effectively increased rumen fermentation products, RUDP, and soluble protein without disturbing the activity of rumen bacteria.
