The aims of study were to evaluate the use of fermented of oil palm fronds (FOPF) on body weight gain and meat quality of goat. This experiment was arranged in Completely Randomized Design with 3 treatments 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 and percentage of carcass and meat quality. The results indicated that feed intake and meat quality of goat was not affected by treatment, but the average daily gain, carcass weight, and percentage of carcass, was affected by the differences of percentage of FOPF in the pellet complete feed. The best ration was in the R1 ration (grass 0%: FOPF 100%) that significantly different (P<0.05) from the other rations. The feed intake tended to be higher in goat fed R1 (895.87 g/d) compared to those in goat with the R2 (854.38 g/d) and R3 (851.53 g/d). The average daily gain and carcass weight were higher in goat fed R1 ration compared to those in goat fed R2 and R3. Consequently, the carcass percentage in R1 was higher than those in R2 and R3. The carcass percentage was ranged from 38.41-41.38%. The Ribeye area was higher in goat fed R1 (9.73 cm 2 ) than R2 (8.34 cm 2 ) and R3 (7.76 cm 2 ). In this study, the protein content of goat meat was ranged from 19.06 to 20.71%, lipid content was ranged from 0.703 to 1.106% and water content was range from 72.45% to 74.12%, in which were not different among the treatments. It can be concluded that the use of FOPF in a complete feed could improve performance and meat quality of goat.

The aim of this experiment was to evaluate the performance of fat-tailed rams fed complete feed based oil palm fronds (OPF). This experiment was arranged in Completely Randomized Design (CRD) with 5 treatments and 4 replications i.e. 0, 25, 50, 75 and 100% of OPF substituting fields grass in complete feed for A, B, C, D and E treatments, respectively. Twenty fat-tailed rams were fed twice at 08.00 and 14.00 with pellet of complete feed for 4 months. The result of this experiment showed that OPF significantly influenced nutrient consumption, average daily gain (ADG) and feed efficiency ratio (FER). Oil palm fronds significantly affected (P<0.05) fat-tailed rams's dry matter intake (DMI), organic matter intake (OMI), crude protein intake (CPI), ADG and FER. The highest DMI, OMI, CPI, ADG, and FER of fat-tailed rams was in C treatment and significantly different from the others. It was concluded that C treatment was the best treatment which can give the best fat-tailed rams performance. The OPF can be used to replace the field grass as feed up to 75% proportion in complete feed and could increase the performance and productivity of fat-tailed rams.

<p class="MDPI17abstract"><strong>Objective: </strong>This study aims to determine the nutritional quality of fermented feed containing banana plant waste that will be given to native chickens in Sidolego Village to accelerate the achievement of Sidolego Village as a chicken center village.</p><p class="MDPI17abstract"><strong>Methods: </strong>The ingredients used to make fermented feed were banana tree waste, black garlic, curcuma, maize, rice bran, fish meal, and coconut meal. All ingredients were ground into flour, mixed thoroughly, and fermented using a solution of Effective Microorganisms 4 (6ml EM4: 6gram sugar: 1-liter water). The study was designed into a completely randomized design with 4 treatments; length of fermentation (1, 2, 3, and 4 days) and 5 replications. The parameters were the nutrient content (dry matter, organic matter, crude protein, crude fiber, and crude fat) and metabolizable energy. <strong></strong></p><p class="MDPI17abstract"><strong>Results: </strong>The results showed that the fermentation time significantly affected (P&lt;0.05) the nutrient content and energy of fermented feed. Fermentation for 3 days significantly decreased dry matter, crude fiber, nitrogen-free extract, and metabolizable energy. The fermentation period did not significantly affect organic matter and crude fat content, but it significantly increased crude protein content. <strong></strong></p><p class="MDPI17abstract"><strong>Conclusions: </strong>It was concluded that feed containing banana tree waste fermented using EM4 for 3 days had sufficient nutrients especially crude protein content (20%) and might be offered to the growing local chickens in Sidolego Village and meet their nutrient requirement. It is recommended that the results of this study be followed up on feeding to local chickens kept in Sidolego Village to know its effect on local chicken performance.<strong></strong></p><p> </p>

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.
