Local buffalo rumen fluid is a source of fiber digesting bacteria. Such bacteria presumably are well adapted to feed stuffs derived from agricultural byproducts with low quality. The purposes of this study were: (1) to isolate the fiber-digesting bacteria from buffalo rumen fluid, (2) to determine the fiber digesting characteristics and adaptability of such bacteria, and (3) to characterize the bacterial diversity. Rumen fluids for the experiment were collected from buffaloes slaughtered at the Faculty of Animal Science, Bogor Agricultural University abattoir. Fiber-digesting bacteria were isolated using McDougall buffer supplemented with fibrous feed. A factorial experiment was conducted to study characteristics and adaptability of the bacteria using two factors: the type of bacteria and type of feed source of the fiber. Diversity among the bacteria was analyzed using the NTSys2.10 program.Results showed that nine bacterial isolates had a high adaptability to fiber feed based on CMCase. The highest CMCase activity bacteria for Pennisetum purpureum were A9 (11.36±1.70 unit/ml/h), A3 (11.22±0.60 unit/ml/h) and A42 (10.62±1.96 unit/ml/h). CMCase activity of fiber digesting bacteria from buffalo rumen fluid was not correlated with the number of bacteria in the culture. Based on genetic similarity, nine isolates were grouped into five types having similarity≥46%. Key Words: Buffalo Rumen Fluid, Fiber-Digesting Bacteria, Low Quality Forage

Murdannia bracteata is one of potential forages for ruminant that has not been studied yet. This forage contents high mineral and it can be as fungtional feed. The aim of this study was to evaluate the growth and productivity, chlorophyll and minerals content of Murdannia bracteata caused by magnesium foliar application. The experiment was arranged in randomized complete design with five treatments and 4 replications. The application of magnesium level was arranged into: 0 ppm, 2000 ppm, 4000 ppm, 8000 ppm, and 12000 ppm. The study was conducted in a greenhouse, field laboratory of Agrostology, Faculty of Animal Science, Bogor Agricultural University. The result showed that growth, productivity, and chlorophyll content were not significantly (P>0.05) affected by increasing magnesium level. Increasing magnesium dossage resulted in decreasing calsium, potassium, and zink content (P<0,05), but not on phosphor and sodium (P>0,05). In conclusion, increasing magnesium dossage up to 12000 ppm did not significantly affect growth, productivity, and chlorophyll content. However, increasing magnesium level decreased calsium, potassium, and zink content.

Duckweed (Lemna minor) is a small aquatic plant that grow and float in water and spread extensively. Lemna minor is potential as a source of high quality forage. This study aimed to determine optimal light intensity on Lemna minor to generate maximum productivity. Parameters observed were physical-biological and chemical characteristics of the media (pH value, temperature, cover area, decreased of media volume, BOD, COD, nitrate, nitrite and phosphate), plant growth acceleration (number of shoots, leaf diameter and chlorophyll-a), biomass production, doubling time of cover area and the number of daughters. This study was done based on a completely randomized design with 4 levels of shading. While treatment was: without shading, shading 30%, shading 50% and shading 70% using paranet shade. Each treatment consisted of 4 replications. Result showed that the productivity of Lemna minor included the number of daughters, chlorophyll-a, biomass production, cover area, absorbed phosphate and doubling time the number of daughters reached the highest level without shading treatment (1007,21-2813,57 lux). The decrease of intensity of light, the increase the diameter of leaf. Decrease of media volume was positively correlated to size of cover area. Biomass production influenced by a wide doubling time of cover area and number of daughters.

Fiber-digesting bacteria are the main rumen bacteria that play an important role in digesting feed. These bacteria are adapted to low quality forage from agricultural byproduct. The aim of these study was to determine the potency of fiber-digesting bacteria consortium obtained from buffalo rumen inoculated to Frisian Holstein calves during preweaning on feed consumption, utilization, mineral uptake and physiological status. This study used 14 isolates of bacteria obtained from collection of Faculty of Animal Science, Bogor Agricultural University. The experimental unit consisted of six Frisian Holstein calves at two week old with the average body weight of 38.00 ± 6.23 kg. Calves were inoculated by 20 ml of fiber-digesting rumen bacterial isolates [4.56 x 109 cfu/ml] every morning for four weeks. Experimental design used was based on a completly randomized design with three calves received the respective inoculation (treatment group) and three calves without any inoculation (control group). Data were analyzed statistically using t-test method with α = 0.05 and 0.01. The results showed that fiber-digesting bacteria (FDB) from rumen buffalo have adapted in the calves rumen since preweaning periode. Inoculation FDB increased the number of rumen bacteria, digestibility of protein and P uptake calves at eight weeks old. Increased feed intake, uptake of Mg and cobalt calves at 14 weeks old. Without causing any negative effects on ADG, physiological status and rumen fermentability. Key Words: Fiber-Digesting Bacteria, Nutrient Intake, Rumen Fermentability

PRODUKTIVITAS TENAGA PENGARIT BERDASARKAN MODA PENGANGKUT DI PETERNAKAN SAPI PERAH PONDOK RANGGON, JAKARTA TIMUR Iwan Prihantoro; M.A. Setiana; Annisa Bahar

Penelitian ini bertujuan untuk menganalisis produktivitas tenaga pengarit dan efektivitasnya berdasarkan moda pengangkut yang dipergunakan di peternakan sapi perah Pondok Ranggon, Jakarta Timur. Peternakan sapi perah Pondok Rangon merupakan salah satu peternakan yang masih bertahan di DKI Jakarta yang ketersediaan hijauan pakannya berasal pada padang rumput alam. Penelitian didasarkan pada sumber data primer dan sekunder dengan cara sensus dari total 22 peternak. Hasil penelitian menunjukkan bahwa karakteristik peternak di Pondok Rangon 40,91% telah berumur > 55 tahun dan 45,46% telah memiliki pengalaman >20 tahun. Kapasitas mengarit tertinggi pada umur 38 tahun (395 kg/hari) dan moda truck lebih efisien dalam penyediaan hijauan dibanding pick up dan becak motor.

The Daarusa'adah farmer group had a cattle breeding program using 20 local heifers. The limited knowledge and skills in managing the farm made the breeding program did not run optimally. The community service program, therefore, aimed to conduct training of cattle production and flushing feed technology application to support breeding program at farmer. This activity was carried out in Pangkal Jaya Village, Nanggung District, Bogor Regency, West Java, through three stages: 1). Training on beef cattle production and breeding program, 2). Assessment of the reproductive organs and health status and 3). Application of flushing feed in beef cattle at farmer level. There were 15 farmers who participated in this program. The data of training questionnaire were analyzed using the Wilcoxon signed-rank test to determine statistic significant differences of their knowledge between before and after the training program. The cattle performance data due to flushing feed application were analyzed descriptively. The results of showed that farmers were increase their knowledge and skills significantly in all production aspects of production and breeding cattle (P<0.05) due to the training program. Application of flushing feed increase the body condition score (BCS) and body weight of the heifers. However, 50% of heifers have ovarian hypofunction based on rectal palpation. Therefore, it can be concluded that the training program of community service activities have succeeded increase the knowledge and skill of farmers. Furthermore, application of flushing feed increases the performance of heifers to support the cattle breeding program.
