Rice straw of Cisadane var. were fermented using different levels of the fortified rumen content (10, 15, and 20% of dry matter) for 4, 6, and 8 weeks. The fermented rice straw then were determined its NDF and ADF contents and its in vitro dry matter and organic digestibility (IVDMD and IVOMD), respectively. The treatments were alloted to completely randomized design with a 3 x 3 of factorial pattern. Data were anlyzed using ANOVA and polynomial orthogonal test were used to study the pattern of each treatment effect. The interactive effect of treatments did not affect the parameters observed significantly, but the fortified rumen content levels increased linearly (P<0.05) the IVDMD and IVOMD of rice straw. The fermentation times increased (P<0.05) the ADF content of rice straw in a quadratic manner. The fortified rumen content level of 20% and fermentation time of 8 weeks improved the in vitro digestibility of rice straw. The data of an experiment from in vitro digestibility is needed to establish this rice straw processing. Keywords : rice straw, fermentation, rumen, digestibility, in vitr

    This experiment was objected to study the in vitro rumen fermentability on the processed vegetable waste. The study was accomplished by two experiments. The first experiment was aimed to select the best processing for vegetable waste. The vegetable wastes from a traditional market in Semarang City were fermented using Lactobacillus bulgaricus and rumen bolus with cassava waste, rice bran, and maize grain as additives. In each combined treatment of innoculant and additive was fermented in anaerob conditon for 0, 1, 2, and 3 weeks, respectively. In each combined treatment of innoculant, additive, and fermentation time was analyzed for its moisture, crude protein, crude fiber, neutral detergent fiber and acid detergent fiber content. Among the combined treatments were then selected the best processing for vegetable waste ac-cording to the use of L. bulgaricus and rumen bolus, respectively. The selection was determined on the basis of a numerical score for each parameter observed. The results showed that the combination of rice bran of additive and one week of fermentation was the best for fermentation using L. bulgaricus (SSLB). Likewise, the the combination of rice bran of additive and two weeks of fermentation was the best for fermentation using rumen bolus (SSBR). In the second experiment, the processed vegetable wastes from the result of first experiment (SSLB and SSBR) were compared to Pennisetum purpureum (RG), unprocessed vegetable waste from the garbage collecting terminal in Semarang City (SSTPA), and unprocessed vegetable waste from traditional market (SSPT) on the basis of their in vitro rumen fermentability. Parameters of the in vitro rumen fermentability were dry matter (DM) and organic matter (OM) digestibility, rumen production of VFA and N-NH 3 . The test of in vitro rumen fermentability was conducted using cattle rumen liquid and artificial saliva. The results showed that the DM and OM digestibility of RG was lower (P<0,05) than that of SSPT, but there was no siginificant different among SSTPA, SSLB, and RG in their DM and OM digestibility. The in vitro rumen VFA production among RG, SSTPA, SSLB, and SSBR were not different significantly. The in vitro rumen VFA production of SSPT was higher (P<0,05) than that of RG, SSTPA, SSLB, and SSBR. The in vitro rumen NH 3 production among SSPT, SSLB, and SSBR were not different significantly. The in vitro rumen NH 3 production of RG and SSTPA were lower (P<0,05) than that of SSPT, SSLB, and SSBR. The fermen-tation using L.bulgaricus with rice bran for one week was appropriate in processing the vegetable waste. The results could be utilized for further study focusing on the substitution of Pennisetum purpureum with the processed vegetable waste in a ruminant ration.

    The aim of the experiment was to find the most appropriate supplement for sheep fed on vegetable waste silage???based diet to produce better weight gain. Sixteen male local sheep (average body weight of 13.27+2.82 kg ) were randomly divided into four groups according to completely randomised design. Each group received one of four treatments i.e. T0 (50% field grass + 50% concentrate), T1 (50% silage of vegetable waste + 50% concentrate), T2 (T1 diet + mineral Zn 20 ppm, Cr 2 ppm), and T3 ( T2 diet + 1% alginate). After two weeks of preliminary period, sheep were subjected to 12 weeks of observation. In general, the vegetable waste silage based diet (T1,T2, T3) resulted in better crude protein (CP) intake and weight gain than the T0 diet. Each treatment of T0, T1, T2, and T3 resulted in Protein consumption of 36,48 ; 45,81 ; 53,59 ; 40,75 g, and weight gain of 75; 105; 121; 109 g/day, respectively. Mineral supplementation (T2) resulted in higher rates of weight gain and feed efficiency compared to the mixed mineral and alginate supplementation (T3), therefore leading to the conclusion that only Zn and Cr mineral supplementation is needed for the vegetable waste silage used as sheep ruminant feed

    Sixteen Ettawah cross bred goats were used to study the effect of waru leaf (Hibiscus tiliaceus)sapponin combined with soybean meal protein supplementation on some parameters of proteinmetabolism. Goats had body weight average of 16 kg and aged at 7 months. The experimental dietswere: T0 = total mixed ration (0.9% saponin of hibiscus leaf, 8% CP, 62% TDN), T1 = T0 + 3% soybeanmeal protein, T2 = T0 + 6% soybean meal protein, and T3 = T0 + 9% soybean meal protein. Thetreatments were allocated in a completely randomized design. The parameters observed in this studywere dry matter (DM) and crude protein (CP) intakes, DM and CP digestibilities, ruminal amonia andVFAs concentrations, blood urea level, nitrogen retention, digestible organic matter in rumen (DOMR),urinary allantoin, and estimated microbial nitrogen (N) synthesis. DM intake, DOMR, urinary allantoinand estimated microbial N synthesis were not affected significantly (P>0.05) by treatments. CP intake,DM and CP digestibilities, ruminal amonia and VFAs concentrations, blood urea level and nitrogenretention increased (P<0.05) with increasing levels of soybean meal protein. Balancing energy levelshould be considered for the dietary protein supplementation in Hibiscus tiliaceus leaf contained diet of goat
