To study the effect of utilization of passion fruit hulls (Passiflora edulis Sims f. edulis Deg) as feed component on consumption, digestion and nitrogen retention in kacang goats, a trial was conducted using 20 young kacang goats (average initial body weight 23.73Â±2.16 kg). The experiment was arranged in completely randomized design consisting of 4 diets and 5 replications. Animal were randomly allocated into 4 diets (0, 15, 30, 45% of passion fruit hulls). Each diet contains 2550 Kcal/kg metabolism energy and 14% crude protein. The feeding level was set at 3.8% of body weight based on dry matter. The results of the experiment showed that average dry matter intake, nutrient digestibility, and nitrogen retention were not affected by level of passion fruit hulls (P>0.05), although nutrient digestibility and nitrogen retention tended to decrease with the increasing level of passion fruit hulls. It was concluded that passion fruit hulls can be used till 45% level in the diet. Key Words: Passion Fruit, Consumption, Digestibility, Nitrogen Retention, Kacang Goat

Penelitian ini bertujuan untuk mengisolasi bakteri pendegradasi mimosin dari cairan rumen domba dan sapi yang diberi pakan mengandung daun lamtoro dan menganalisis pengaruh inokulasi bakteri pendegradasi mimosin pada karakteristik fermentasi rumen secara in vitro. Tahap pertama adalah isolasi bakteri pendegradasi mimosin dari cairan rumen domba yang diberi pakan mengandung daun lamtoro 30% dan dari rumen sapi Bali di Sumbawa yang diberi pakan daun lamtoro 100%. Tahap kedua adalah inokulasi bakteri pendegradasi mimosin pada fermentasi in vitro dengan substrat mengandung daun lamtoro. Rancangan yang digunakan pada percobaan in vitro adalah rancangan acak kelompok pola faktorial dengan 2 faktor. Pengelompokan berdasarkan waktu pengambilan cairan rumen. Faktor pertama terdiri dari 3 taraf daun lamtoro yaitu 0, 30, dan 60% dalam ransum. Faktor kedua terdiri dari 2 inokulasi pendegradasi mimosin yaitu dengan dan tanpa inokulasi bakteri pendegradasi mimosin. Peubah yang diamati adalah populasi bakteri dan protozoa, nilai pH, konsentrasi NH3, produksi volatile fatty acid (VFA), kecernaan bahan kering (KcBK) dan kecernaan bahan organik (KcBO). Hasil penelitian ditemukan 2 isolat bakteri pendegradasi mimosin dari rumen domba dan 3 isolat rumen sapi Bali. Kelima isolat tersebut mempunyai kemiripan dengan Streptococcus sp. Hasil uji in vitro menunjukkan tidak ada interaksi antara taraf pemberian daun lamtoro dengan inokulasi bakteri pendegradasi mimosin pada fermentasi rumen. Inokulasi bakteri pendegradasi mimosin dapat meningkatkan konsentrasi NH3 dan cenderung memperbaiki produksi VFA dibandingkan dengan perlakuan tanpa inokulasi bakteri. Nilai pH, KcBK dan KcBO tidak berbeda antar perlakuan. Kesimpulan yang dapat diambil adalah inokulasi bakteri pendegradasi mimosin dapat menstimulasi fermentasi rumen secara in vitro.

The aims of this study were to screen and characterize lactic acid bacteria (LAB) isolated from gastrointestinal (GI) tract of Cemani chicken, one of Indonesian local chicken and to investigate their potential use as probiotics. LAB were isolated from GI tract using MRSA and GYPA media and incubated anaerobically. Selected LAB were determined their probiotic properties with several assays. Identification of selected LAB was based on 16S rDNA sequences, morphological and biochemical characteristics. Ninety five bacteria were isolated and characterized as lactic acid bacteria (Gram positive, catalase negative, non sporeforming and acid producing). Twenty four isolates of LAB demonstrated antimicrobial activity against Escherichia coli JCM 1649 and Salmonella enteritidis B2586, and three selected isolates, i.e. CCM011, CSP004, and CVM002 showed the highest inhibition activity. The isolates had characters of high cell surface hydrophobicity and inter-isolate coaggregation ability of LAB, high survival at low pH, high phytase and protease activity (but no amylase and lipase activity), weak coaggregation with pathogen and no resistance to the examined antibiotics. The isolates were identified based on sequence analysis of 16S rRNA gene as Lactobacillus salivarius, however, each isolate had different profiles of sugar fermentation. Therefore the three LAB isolates had potential application as probiotics for chicken.Key words: Cemani chicken, gastrointestinal tract, lactic acid bacteria, probiotic

Lactic acid bacteria (LAB) regarded as safe microorganisms; they can naturally live in gastrointestinal tract, so appropriately used as a probiotic for chicken. This study aimed to select six isolates of LAB (E1223, E3, E4, E5, E7, and E8) to obtain the isolates potentially as probiotic candidate for chicken. The six isolates were derived from spontaneous fermented corn obtained from Laboratory of Animal Biotechnology and Biomedical, PPSHB, Bogor Agricultural University, Indonesia. LAB isolates were tested their susceptibility to antibiotics (bambermycin, erythromycin, chloramphenicol, and tetracycline) then were examined in vitro for their tolerance to gastrointestinal pH (2, 3, 4, and 7.2) and 0.5% bile salt condition, antimicrobial activity against Salmonella enteritidis and Enterococcus casseliflavus, and ability to adhere to chicken ileal cells. The results showed the isolates E5, E7, and E8 were sensitive to tetracycline and chloramphenicol, they could survive at pH 2, 3, 4, and 7.2, could survive at 0.5% bile salts, produced antimicrobial activity, and able to adhere to ileal cells (9.40±0.00 Log CFU/cm2 of E8) and were significantly (P<0.05) higher than those of control (5.30±0.14 Log CFU/cm2). In conclusion, this study showed that isolate E8 had better potential compared to isolates E5 and E7 in most in vitro assays as a probiotic candidate for chicken. E5, E7, and E8 were closely related with Pediococcus pentosaceus based on 16S rRNA gene.Key words: LAB, probiotic, chicken, in vitro

This study was aimed to evaluate the effect of complete rations containing soybean pod and soybean by-products (soybean meal and tofu waste) on rumen microbial population, fermentation characteristics, nutrient digestibility, and nitrogen retention of Madura cattle. Twelve Madura cattle of 1.5 years of age were given 4 feeding treatments in triplicates in randomized block design experiment. The treatments included T0 (100% native grass) as a negative control, T1 (concentrate: grass (60:40) as a positive control, T2 (complete ration containing 15% soybean pods), and T3 (complete ration containing 30% soybean pods). The treatments were based on feeding practices commonly applied by farmers in the village. The results showed that the use of concentrate rations or complete rations containing soybean pod and by-product did not affect protozoa population, ammonia concentration, and total VFA production compared to cattle fed 100% native grass. In contrast, the use of concentrate rations or complete rations containing soybean pod and by-products reduced acetate and increased butyrate proportion compared to native grass. The use of a concentrate ration resulted the highest propionate proportion. Methane estimation increased with the use of concentrate ration or complete ration containing 15% soybean pod, but it decreased when the level of soybean pod was increased to 30%. It can be concluded that soybean pod has a potential to be used as a fiber source in beef cattle ration to substitute native grass.

Sorgum G5 dan G8 adalah dua sorgum galur mutan yang diproyeksikan sebagai sorgum khusus pakan ternak. Sampai saat ini, belum terdapat cukup informasi terkait profil serat yang terkandung dalam kedua galur mutan tersebut. Profil serat yang diasosiasikan dalam fraksi neutral detergent fiber (NDF) dan acid detergent fiber (ADF) akan mempengaruhi kecernaan tanaman sorgum. Tujuan dari penelitian ini adalah untuk: 1) mengevaluasi profil fraksi serat dan mengestimasi relative feed value (RFV) pada tanaman sorgum galur mutan, 2) mengevaluasi profil serat pada fase generatif yang berbeda, dan 3) mengetahui profil serat sorgum secara kualitatif menggunakan fourier transform mid-infrared (FTIR). Rancangan yang digunakan adalah rancangan acak kelompok pola faktorial (4x3x3). Faktor pertama adalah varietas/galur mutan tanaman (varietas Numbu, Pahat, galur mutan G5 dan G8). Faktor kedua adalah waktu pemanenan (flowering, soft dough dan hard dough). Faktor ketiga adalah Bagian tanaman (batang, daun dan malai sorgum). Parameter yang diamati adalah profil serat kuantitatif (NDF dan ADF), RFV dan profil serat secara kualitatif menggunakan FTIR. Hasil penelitian menunjukkan bahwa terdapat pengaruh perbedaan varietas/galur mutan, fase generatif dan bagian tanaman terhadap profil serat tanaman sorgum. Terdapat interaksi antara perbedaan varietas/galur mutan dengan fase generatif tanaman. Sorgum G5 fase hard dough menghasilkan kandungan NDF batang yang lebih rendah dibandingkan Numbu (54,23 % vs 60,41 %) (P<0,01). Sorgum G8 fase hard dough menghasilkan kandungan ADF daun yang lebih rendah dari Numbu (30,07 % vs 32,63 %) (P<0,01). Nilai RFV tertinggi pada bagian batang, daun dan malai berturut-turut dihasilkan oleh sorgum G5, G8 dan Pahat. Hasil pengukuran kualitatif menggunakan FTIR berasosiasi dengan pengukuran NDF dan ADF secara konvensional. Kesimpulan dari penelitian ini adalah: 1) galur mutan G5 dan G8 menghasilkan fraksi sera yang lebih mudah dicerna dibandingkan varietas Numbu. Hal tersebut ditunjukkan oleh nilai RFV yang tinggi pada bagian batang dan daun; 2) Fase hard dough adalah umur panen yang terbaik; dan 3) FTIR dapat digunakan untuk menggambarkan profil serat sorgum secara kualitatif.

Sorghum is one of potencial fibre sources as buffalo feed. Quality of sorghum could be increased by irradiation mutation breeding. Samurai 1 and Samurai 2 were products of the irradiation mutation breeding of Pahat. This study was conducted to compare buffalo diets containing Samurai 2 sorghum straw and Samurai 1 bagasse sorghum compared with Pahat sorghum straw using in vitro study. Completely randomized design with 6 treatments and 3 replications was applied in this experiment. The treatment diets were P1 (50% Pahat sorghum straw + 50% concentrate), P2 (50% Pahat sorghum straw silage + 50% concentrate), P3 (50% Samurai 2 sorghum straw + 50% concentrate), P4 (50% Samurai 2 sorghum straw silage + 50% concentrate), P5 (50% Samurai 1 sorghum bagasse + 50% concentrate) and P6 (50% Samurai 1 sorghum bagasse silage + 50% concentrate). The 200 mg DM samples of diets were incubated in 30 ml rumen-buffer fluid for 48 hours. Variables measured were total gas production, CH4 production and rumen fermentation characteristics. Results showed that P2 and P4 produce the highest of gas production (P<0.05) with 60.99 and 60.86 ml/200 mg dry matter respectively. Treatments of P1, P2 and P4 produced the lowest CH4 concentration (P<0.05) with 10.57, 10.90 and 9.82% of total gas, respectively. The P4 produced the highest total volatile fatty acids (VFA), dry matter degradability and organic matter degradability with 109.83 mM, 62.93% and 59.97% respectively, meanwhile ammonia (NH3) concentration was not significantly different. The conclusion showed that straw silage of Samurai 2 was comparable to the Pahat sorghum straw and Samurai 1 bagasse sorghum as buffalo diet.
