Pengaruh Dosis Inokulum Marasmius SP. Dan Lama Inkubasi Terhadap Kandungan Komponen Serat Dan Protein Murni Pada Sabut Kelapa Sawit Untuk Bahan Pakan Ternak

The objective of the experiment was to find out the best inoculum dosage and incubation time for fiber component percentage and true protein percentage. The experiment was arranged by a Completely Randomized Design with factorial pattern 4x4, which the first factor was inoculum dosage (D2,5=2,5%; D5=5%; D7,5=7,5%; and D10=10%) and the second factor was incubation time (W1=1 week, W2= 2 week, W3 = 3 week, and W4= 4 week), the treatment combination were replicated 3 times which component fiber percentage and true protein percentage as parameters. All data were analyzed by analysis of variance followed DMRT. The results of experiment showed that there was significant interaction between inoculum dosage and incubation time on fiber component and true protein percentage. The lowest of fiber component especialy lignin and highest true protein percentage were found at D3W3 combination treatment, which the fiber componen percentage was NDF (67.63%), ADF (60.50%), selulosa (45.27%), lignin (9.93%), and True protein (8.957%)

The Effect of Fermented Oil Palm Fronds in Diet on Body Weight Gain and Meat Quality of Goat

The aims of study were to evaluate the use of fermented of oil palm fronds (FOPF) on body weightgain and meat quality of goat. This experiment was arranged in Completely Randomized Design with 3treatments i.e. R1 (grass 0%: FOPF 100%), R2 (grass 50%: FOPF 50%) and R3 (grass 100%: FOPF 0%)and 5 replications. The parameters of the study were feed intake, average daily gain (ADG), weight andpercentage of carcass and meat quality. The results indicated that feed intake and meat quality of goatwas not affected by treatment, but the average daily gain, carcass weight, and percentage of carcass, wasaffected by the differences of percentage of FOPF in the pellet complete feed. The best ration was in theR1 ration (grass 0%: FOPF 100%) that significantly different (P<0.05) from the other rations. The feedintake tended to be higher in goat fed R1 (895.87 g/d) compared to those in goat with the R2 (854.38g/d) and R3 (851.53 g/d). The average daily gain and carcass weight were higher in goat fed R1 rationcompared to those in goat fed R2 and R3. Consequently, the carcass percentage in R1 was higher thanthose in R2 and R3. The carcass percentage was ranged from 38.41-41.38%. The Ribeye area was higherin goat fed R1 (9.73 cm2) than R2 (8.34 cm2) and R3 (7.76 cm2). In this study, the protein content ofgoat meat was ranged from 19.06 to 20.71%, lipid content was ranged from 0.703 to 1.106% and watercontent was range from 72.45% to 74.12%, in which were not different among the treatments. It can beconcluded that the use of FOPF in a complete feed could improve performance and meat quality of goat

Evaluasi Suplementasi Indigofera Zollingeriana sebagai Sumber Green Protein Concentrate terhadap Produksi Gas Metan, Amonia dan Sintesis Protein Mikroba Rumen

The use of protein with low-cost, high quality, low methane, and ammonia emissions are a prerequisite as a protein source in ruminant. However, the European Commission has prohibited protein derived from fish meals for ruminant feeds. So encouraging efforts to explore the other protein sources to be most important. Most of the high protein legumes grow in tropical areas such as Indonesia and have the potential as an alternative protein source in ruminant feed, including Indigofera zollingeriana (25-27% protein content). But many browse legumes with high protein are a heterogeneous group of plants, with variable secondary metabolic content and rumen degradable protein. The aim of this experiment was to evaluate the characteristics fermentation of IZ as green protein supplement on in vitro methane, ammonia and microbial protein production. The experiment was a completely randomized design with four different level supplementation of Indigofera zollengeriana (IZ) as green protein concentrate and five replications. The treatment diets were R0; basal diet (60% forage + 40% concentrate) + 0% IZ, R1; R0 + 10% IZ, R2; R0 + 20% IZ, and R3; R0 + 30% IZ. The experiment result showed that supplemenatation of IZ was significant effects (P<0.05) to increase total gas, ammonia (N-NH3), total volatile fatty acid (TVFA), and metabolizable energy (ME) and significant effect (P<0.05) to decrease of methane and methane percentage. Supplementation IZ at a level of 10% was significantly higher for dry matter digestibility (DMD), organic matter digestibility (OMD), and microbial protein production (PPM) than diets treatment of R0, R2, and R3. The experiment concluded that Supplementation of I. zollingeriana (IZ) was able to reduce the methane gas production. Protein characteristics of IZ have easily degradable by rumen microbe showed the ammonia production was linearly increasing by 45.66% for each increasing level of IZ supplementation. Microbial protein production was higher (184.33 mg/ml) obtained of IZ supplementation up to 10% (R1). The experiment suggests doing protected protein of IZ when be used as a protein source in ruminant diets
