  An experiment was conducted for the evaluation of Palm Kernel Cake Fermented (PKCF) by Aspergillus niger as a substitute for soybean meal protein in the diet of broiler. The experiment used a Complete Randomize Design (CRD) with 6 treatments and 4 replications. The treatments were arranged as follows: 1) 0% basic ration (0% PKCF), 2) 20% substitution of soybean meal protein with PKCF, 3) 40% substitution of soybean meal protein with PKCF, 4) 60% substitution of soybean meal protein with PKCF, 5) 80% substitution of soybean meal with PKCF, 6) 100% substitution of soybean meal with PKCF. The ration were formulated in iso protein 22% and iso caloric 3000 k cal/kg ration. This study used a completely randomized design with six treatments and four replications. The parameters of this study were feed consumption, body weight gained, feed conversion and percentage of carcass. The result of this study showed that feed consumption, body weight gained, feed conversion and percentage of carcase were not significantly affected (p>0.05) by any treatment. In conclusion the Palm Kernel Cake Fermented (PKCF) by Aspergillus niger can be 100% a substitute of soybean meal protein or 17% in broiler ration.

  An experiment was conducted to determine the effects of several levels of Neurospora crassa-fermented palm kernel cake in the diet on the production performance of Gold Arab laying-hens and to obtain the appropriate level of this fermented palm kernel cake for reducing the utilization of concentrated feed in the diet. Three hundred Gold Arab laying-hens of 72 weeks old were employed in this experiment and randomly assigned to four treatments (0, 7.25, 10.15 and 13.05% fermented palm kernel cake in diets) in a completely randomized design with five replicates. The measured variable was production performance (feed consumption, egg-mass production, feed conversion, egg weight and hen-day egg production). Results of experiment indicated that feed consumption, egg-mass production, feed conversion, egg weight and hen-day egg production were not influenced (p>0.05) by diets. In conclusion, Neurospora crassa-fermented palm kernel cake could be included up to 13.05% to effectively replace 45% concentrated feed in the diet of Gold Arab laying-hens without adverse effect on the production performance.

  Background and Objective: Palm kernel cake (PKC) can potentially be used as feedstuff, especially for poultry. PKC needs to be processed in advance, by fermentation, with Sclerotium rolfsii. An experiment was conducted to evaluate the utilization of palm kernel cake fermented (PKCF) with Sclerotium rolfsii in the diet of broiler. Materials and Methods: Two hundred day-old chicks (DOC) were used in this study. The diet was arranged based on the equal amount of energy and protein, which were 3000 kcal kg–1 and 22%, respectively. The experiment used a completely randomized design (CRD) with 5 treatments and 4 replications. The treatments were arranged as follows: (1) 10% PKCF (control diet), (2) 15% PKCF, (3) 20% PKCF, (4) 25% PKCF and (5) 30% PKCF in broiler diet. The parameters measured were feed consumption, body weight gain, feed conversion, body weight, carcass weight, crude fiber digestibility and nitrogen retention of broiler. Results: Feed consumption, body weight gain, feed conversion, body weight, carcass weight, crude fiber digestibility and nitrogen retention were highly significantly decreased (p<0.01) with any treatment. Conclusion: The palm kernel cake fermented (PKCF) with Sclerotium rolfsii can be used up to 25% in broiler ration.

  An experiment has been conducted to compare the nutrient contents and nutritional values of palm kernel cake (PKC) from different fermentation processes. This experiment was designed in a Completely Randomized Design (CRD) with six treatments and five replicates. Treatments were A = unfermented PKC (control), B = fermented PKC with Neurospora crassa, C = fermented PKC with Penicillium sp., D = fermented PKC with Trichoderma harzianum, E = fermented PKC with Aspergillus niger and F = fermented PKC with Aspergillus niger+humic acid. Measured variables were nutrient contents (crude protein, crude fiber and ether extract) and nutritional values (nitrogen retention, crude fiber digestibility and metabolizable energy) of fermented and unfermented PKCc. Results of experiment indicated that the crude fiber content of fermented PKCs was very significantly lower (p<0.01) than that of control, but there was no difference (p>0.05) among the fermented PKCs. Fermentation with different fungi increased (p<0.05) the crude protein content of PKCs when it was compared with control. The crude protein content of Aspergillus niger and Aspergillus niger+humic acid fermented PKCs were significantly higher (p<0.05) than that of Trichoderma harzianum, Neurospora crassa, or Penicillium sp., fermented PKCs or control. The ether extract content of PKC was very significantly affected (p<0.01) by treatments. Aspergillus niger+humic acid, Neurospora crassa and Aspergillus niger fermented PKCs possessed the lower ether extract content (p<0.05) than that of Penicillium sp., or Trichoderma harzianum fermented PKCs, or control. The crude fiber digestibility of Aspergillus niger or Aspergillus niger+humic acid fermented PKCs was very significantly higher (p<0.01) than that of Penicillium sp., Trichoderma harzianum, Neurospora crassa fermented PKCs, or control. The nitrogen retention of Aspergillus niger+humic acid fermented PKC was significantly higher (p<0.05) than that of Penicillium sp., Neurospora crassa fermented PKCs, or control, but was not differed (p>0.05) from that of Trichoderma harzianum or Aspergillus niger fermented PKCs. The fermentation with different fungi improved (p<0.05) the metabolizable energy content of PKC. Thus, the improvement of the nutrient contents and nutritional values of Aspergillus niger fermented PKC was better than the other treatments.

  Objective: An experiment was conducted to understand the effects of different microbes and doses of humic acid on the quality and nutrient content of Fermented Palm Oil Sludge (FPOS). Materials and Methods: The experiment was conducted using a 2×3 factorial Completely Randomized Design (CRD) with 3 replications. The first factor was two species of microbe, Neurospora sitophila and Neurospora crassa and the second was different doses of humic acid: (1) 100 ppm, (2) 200 ppm and (3) 300 ppm. The study parameters were the crude protein content, crude fiber content, nitrogen retention and digestible crude fiber content of FPOS. Results: The study parameters were more significantly affected by the interaction between the type of microbe and the dose of humic acid (p<0.01) than the humic acid dose alone. FPOS treated with Neurospora crassa and humic acid at 200 ppm showed better values for crude protein (23.74%), crude fiber (20.14%), crude lipid (2.70%), nitrogen retention (60.97%) and digestible crude fiber (55.63%) compared to FPOS treated with Neurospora sitophila. Conclusion: It is concluded that POS fermented with Neurospora crassa and 200 ppm humic acid provides the best food content and quality of FPOS.

  Background and Objective: Glutamate is a non-essential amino acid and it improves the perception of the taste umami and serves as a building block of protein and physiological functions of the body. Increased use of glutamate in animal feed causes glutamate to rise globally. The aim of this study was to obtain the optimal conditions for glutamate production by Lactobacillus plantarum VM. Materials and Methods: Lactobacillus plantarum VM (L. plantarum VM) is a lactic acid bacteria originating from Minangkabau fermented foods and produces glutamate. The increased production of glutamate from Lactobacillus plantarum VM can be achieved by improving the nutrition and the growth environment of the bacteria. This study was designed in the form of a laboratory experiment protocol and was repeated 3 times. The variables measured in this study were the medium pH, temperature, incubation time, carbon source and nitrogen source. Results: The results of this study showed an optimum 5.5 pH (161.519 mg L–1), incubation time (36 h), temperature (36°C) (350.001 mg L–1), 11% glucose (566,535 mg L–1) and 0.5% peptone (680.525 mg L–1). Conclusion: Optimization of the initial pH of the media, incubation time, temperature, source C and source N can increase glutamate production.

  Background and Objective: Palm oil sludge, as a byproduct of the palm oil industry, is an agricultural waste product that can be used as an alternative feedstuff for poultry. Palm oil sludge also contains nutrients that can be used as feed ingredients for poultry. Palm oil sludge is limited in use in broiler rations because of its low quality and nutrient content. For this reason, it is necessary to process palm oil sludge by fermentation methods to improve the quality and the nutrient content. This study aimed to determine the combined effect of fungi (P. chrysosporium and N. crassa) and fermentation time to improve the quality of fermented palm oil sludge. Materials and Methods: The materials used in this study were palm oil sludge, the fungi Phanerochaete chrysosporium and Neurospora crassa and fermentation materials and tools. This experimental study used a completely randomized design (CRD) with a 3×3 factorial pattern with 3 replications. The treatments consisted of factor A (combination of Phanerochaete chrysosporium and Neurospora crassa), which consisted of A1 (3:1), A2 (3:2) and A3 (4:1) and factor B (fermentation time), which consisted of B1 (7 days), B2 (10 days) and B3 (13 days). Results: The results of the analysis of variance showed that there was a significant interaction (p<0.05) between factor A and factor B. Each factor A and B showed a significant effect (p<0.05). Conclusion: In this study, it was concluded that the combination of Phanerochaete chrysosporium and Neurospora crassa (4:1) and 13 days of fermentation time provided optimal results, with 26.20% crude protein, 14.49% crude fiber, 14.54% lignin, 58.20% nitrogen retention and 57.66% crude fiber digestibility.
