The research was conducted to study the growth characterization of Trichoderma reesei, the degradability of mannan polysaccharides from Palm Kernel Cake (PKC) with different concentrations of fungi and thickness of the PKC medium, as well as the improvement of the nutritive value of palm kernel cake. Experiment 1 was to study the growth characterization of Trichoderma reesei, and Experiment 2 was conducted using concentrations of fungi (104, 105, and 106 CFU per cc) and thickness of the PKC medium (1, 2, and 3 cm). The research used a completely randomized design with factorial 3 x 3. The treatments resulted in significant (P<0.05) differences on pH and temperature of PKC medium, ADF, NDF, crude protein, and hemicellulose.Â There were interaction effect on the concentrations of fungi and on the thickness of PKC medium (P<0.05) on NDF, crude protein, and hemicelluloses (P<0.05). Experiment 3 was conducted to study the True Metabolizable Energy (TME), the retention of nitrogen, total sugar and mannan content. Results showed that Trichoderma reesei was able to degrade mannan polysaccharides of PKC whereby TME and the total sugar value increased, but the nitrogen retention and mannan content decreased.

CASREA is protein supplement (PS) based on extruded-cassava-urea as main materials.Â The objective of this study was to examine the CASREA characteristics by evaluating ammonia concentration (NH3), Volatile fatty acids (VFA), rumen microbial protein synthesis (RMPS), and protein digestibility post rumen (PDPR). Variables of NH3, VFA and RMPS were analyzed with a completely randomized design in factorial (4X3), namely CASREA as factor A, consisted of: Casrea1 (made from 32% urea and 58% cassava without extrusion), Casrea2 (extrusion 22% urea and 68% cassava), Casrea3 (extrusion 27% urea and 63% cassava), and Casrea4 (extrusion 32% urea and 58% cassava), whereas the factor B was incubation times, consisted of Â 2, 4, and 6 hours incubation time. Variable of PDPR was analyzed with a completely randomized design, and the treatments were Casrea1, 2, 3, and 4. Results showed that there were no interactions between CASREA and incubation time on variables of NH3, VFA, and RMPS. Extrusion on CASREA materials reduced (P<0.05) NH3 and VFA, but increased (P<0.05) RMPS and PDPR.Â The highest RMPS and PDPR were 29.04 mg and 76.16%, respectively and were attained by Casrea2. Â Casrea1 had the highest NH3 (43.42 mM), whereas Casrea2 had the lowest (29.65 mM).Â Meanwhile, NH3 caused by Casrea2, Casrea3, and Casrea4 was 29.65, 30.54 and 31.44 mM, respectively and the increase these values were not significantly different. The concentration of NH3, VFA, and RMPS were stable on 4 hours incubation time. The present findings suggest that CASREA made from extrusion of 22% urea and 68% cassava as main materials was PS for slow release of ammonia (SRA) in the rumen due to reduction of NH3, but it improved the utilization of nitrogen for rumen microbial protein synthesis.Â (Animal Production 10(1): 34-41 (2008)Â Key Words: Extruded-cassava-urea, protein supplement, slow release of ammonia

ABSTRAK Tujuan penelitian ini adalahmembuat kartu skor (score card) untuk penilaian sistem grading dan kontes kambing kaligesing. Hasil penelitian menunjukkan bahwa terdapat tiga faktor determinan dalam sistem grading kambing kaligesing yang telah lama berlaku di tingkat peternak, yaitu faktor ukuran tubuh, profil muka dan leher, serta ukuran telinga. Penilaian eksterior pada kambing perah biasanya menggunakan kartu skor yang seragam dan telah dibakukan. Kartu skor dibuat berdasarkan ketiga faktor determinan sistem grading menurut peternak. Kartu skor terdiri atas komponen-komponen penilaian kuantitatif dan kualitatif. Komponen kuantitatif meliputi ukuran badan dan ukuran telinga dengan bobot total 70%, komponen kualitatif meliputi profil kepala dan leher dengan bobot total 30%. Komponen ukuran badan memiliki bobot terbesar (55%) dibandingkan dengan komponen yang lainnya. Hal tersebut dimungkinkan karena ukuran badan banyak digunakan dalam proses jual beli Kambing PE, misalnya tinggi pundak dan bobot badan (Kambingetawa 2011). Komponen profil kepala dan leher memiliki bobot 30%. Semakin cembung mukanya maka semakin dicari para penggemar Kambing Kaligesing. Demikian pula dengan gelambir, semakin bergelambir semakin menarik. Komponen ukuran telinga memiliki bobot 15% dari total penilaian. Ukuran telinga memberikan kontribusi bobot terhadap penilaian keseluruhan dari seekor Kambing Kaligesing karena merupakan ciri khas Kambing PE dan Kambing Kaligesing. Semakin panjang dan lebar telinga kambing, maka semakin tinggi skor nilai yang diperoleh.

ice straw and bran are low in protein. This study examined protein supplement (SPN) composed of CASREA (cassava-urea complex) and SOYXYL (protected-protein soybean meal) in rice straw and bran based ration offered to beef cattle. Experiment 1: Casrea1 (no extruded 32% urea and 58% cassava), Casrea2 (extruded 22% urea and 68% cassava), Casrea3 (extruded 27% urea and 63% cassava), and Casrea4 (extruded 32% urea and 58% cassava) were incubated in ruminal fluid. Experiment 2: Protected-protein soybean meal with xylose from Black LiquorÃ¢â‚¬â„¢s (BL) of 0, 3, 6, or 9% and extruded at 120, 150, or 180oC, were incubated in ruminal fluid. Experiment 3: The best treatments of experiments 1 and 2 were used as SPN. Sixteen dairy cattle bulls aged 12-15 months were divided into 4 blocks to receive one of the following treatments: R0= rice straw and bran, R1= R0 with SPN A, R2= R0 with SPN B, R3= R0 with SPN C. SPN A, B and C composed of CASREA:SOYXYL in ratio of 20:80, 50:50, and 80:20, respectively. Casrea 2 had the highest microbial protein and post rumen protein digestibility of 29.04 mg and 76.16%, respectively. Protected-protein soybean meal with xylose from BL 3% and extruded at 1500C had the highest microbial protein and post rumen protein digestibility. SPN increased dry matter, organic matter and protein intake and their digestibility, ration efficiency, and daily gain. The highest daily gain (0.85 kg.d-1), ration efficiency (11%), and income over feed cost (Rp 7500 head-1.d-1) were R3. R3 had lower methane energy compare to R0. The result indicated that JDP supplemented with SPN (80% CASREA and 20% SOYXYL) improved ration efficiency and performance of cattle. Key words: rice straw, rice bran, cassava, urea, soybean meal

The experiment was conducted to determine the optimum synchronization ratio of N-protein and fermented organic matter (OM) in the rumen for the purpose of ration formulation for ruminant animals, in order to improve efficiency of rumen microbial N synthesis and feed efficiency. Nylon bag technique was adopted to determine ruminal characteristic of protein and OM degradation of feedstuffs (forage and concentrate diet) for which the synchronized index of N-protein and fermented OM in the rumen might be determined. By randomized block design, twelve local cattle were arranged to four groups. Each group was fed three types of diet that was different in synchronization ratio of supplying N-protein and fermented OM in the rumen, namely 20 g N/kg OM (R20); 25 g N /kg OM (R25); and 30 g N /kg MO (R30). The diets had iso-energy and iso-protein contents and had the same synchronization index. The results showed that the type of diet had no effect (P>0.05) on intake and digestibility of nutrients, N retention, average daily gain (ADG), and feed efficiency. But R20 had better parameter values than those of R25 and R30. It might be concluded that the diet having a synchronization ratio of 20 g N/kg fermented OM in the rumen will generate more efficient protein synthesis of rumen microbes and feed efficiency. Key words: synchronization index, microbial protein synthesis, ruminal characteristic

The objective of this study was to select three strains of probiotic Saccharomyces cerevisiae and to evaluate the effect of S. cerevisiae and rumen bacteria isolate (MR4) supplementation and their combination on rumen fermentability and rumen microbial population. Experiment 1 was designed in a 4 x 5 factorial randomized block design with 3 replications. The first factor was S. cerevisiae strain consisted of control treatment (without S. cerevisiae supplementation), NBRC 10217, NRRL Y 567 and NRRL 12618, and the second factor was incubation time consisted of 0, 1, 2, 3, and 4 h. Ration was basal ration for feedlot with forage to concentrate ratio (F:C)= 60:40. Dosage of each treatment with S. cerevisiae was 5 x 1010 cfu/kg ration. Experiment 2 was designed in randomized block design with 4 treatments: P0= basal ration of feedlot; P1= P0 + S. cerevisiae; P2= P0 + MR4 isolate (5 x 107 cfu/kg ration); P3= P0 + S. cerevisiae and MR4 isolate. The result of experiment 1 showed that supplementation of S. cerevisiae NRRL 12618 had the highest S. cerevisiae population and increased rumen bacterial population. This strain was selected as probiotic in experiment 2. The result from experiment 2 showed that probiotic supplementation stabilized rumen pH and produced the highest NH3 concentration (P<0.05) and bacterial population (P<0.05). As compared with control, all treatments reduced protozoa population (P<0.05). Combination of S. cerevisiae and MR4 probiotics produced the highest total volatile fatty acids (VFA) and isovalerate (P<0.05). It was concluded that strain S. cerevisiae NRRL 12618 had potential as probiotic yeast. Supplementation with this strain increased fermentability, rumen isoacid and decreased A:P ratio. Those abilities could be improved with MR4 rumen isolate probiotic.

This research was aimed to evaluate the effect of inoculant and crude enzyme of Trichoderma reesei on fermentation quality and rumen digestibility of napier grass silage. This research consisted of two stages. The first stage was fermentation quality using a completely randomized design with three treatments and six replications. The second stage was rumen fermentability using a randomized block design with three treatments and six replications. The treatments of both stages were: T0= control of napier grass silage (Hi-fer+), T1= control + T. reesei inoculant at the level of 2.13 x 107 cfu/kg, and T2= control + crude enzyme from T. reesei at the level of 11.4 unit/kg. Napier grass silage were kept at room temperature and opened 21 d after fermentation. The result of the first stage experiment showed that T2 decreased (P<0.01) dry matter, organic matter, crude fiber, and neutral detergent fiber (NDF) and also increased (P<0.05) crude protein, total digestible nutrient (TDN), pH, acetic acid, and propionic acid of napier grass silage while T1 decreased (P<0.01) NDF and increased (P<0.05) propionic acid. The result of the second stage experiment showed that there were no significant differences in rumen pH, in vitro dry matter and organic matter digestibility, total VFA, proportion of VFA, ratio of acetic to propionic acids, and also NH3. It is concluded that the addition of crude enzyme from T. reesei could improve fermentation quality of napier grass silage with decreasing NDF and increasing TDN but did not affect rumen fermentability.

The potential availability of forage feed is high, but in reality this potential has not been able to meet the requirement of feed both in sustainable quantity and quality. Silage made with the use of liquid fermentation additive (FA) can be a solution for those problems. The use of different levels of FA and addition of Lactobacillus plantarum bacteria as well as formic acid were expected to improve the nutritive quality of napier grass silage. The first experiment was designed to measure the fermentative quality of napier grass silage. The treatments used were the levels of FA, L. plantarum, and formic acid supplementations. The experiment used a completely randomized design with a 3x2x2 factorial arrangement with 3 replications. The first factor was the level of liquid FA (5%, 7.5%, and 10%), and the second factor was the inoculation of L. plantarum (without and with inoculation of the L. plantarum), and the third factor was the addition of formic acid (without and with the addition of 0.15% formic acid). The second experiment was aimed to evaluate chemical and microbiological characteristics, and in vitro digestibility of selected napier grass silage. The results showed that napier grass silage from all treatments showed good qualities. There were interactions between FA, L. plantarum, and formic acid on DM content (P<0.05) and ammonia production (P<0.01). The use of FA showed an interaction (P<0.01) with the addition of L. plantarum and formic acid in Fleigh point. Ammonia production in rumen (P<0.01), total VFA (P<0.05), and in vitro digestibility (P<0.01) were significantly affected by the treatments. The optimal level of liquid FA was 7.5%. Based on the nutritive quality of silage, L. plantarum addition was as effective as control treatment to improve nutritive quality of napier grass silage through the increased of fermentation characteristics i.e., low pH, high DM product, high fermentation product (VFA), and digestible on rumen. Formic acid reduced ammonia production during ensiling and fermentation in rumen, but it was less effective in inhibiting the fermentation process when it was combined with L. plantarum.
