  Durian fruit waste (peel and seed) can be used as an alternative feed based on the potential availability and nutrient content. Three experiments were conducted to improve the nutrient quality of durian fruit waste (DW) and tofu waste (TW) mixture through fermentation by using Phanerochaete chrysosporium and Neurospora crassa. The substrates consists of 70% DW (peel and seed in the same proportion) and 30% TW. Experiment 1 was performed in a 3 x 3 factorial experiment of completely randomized design with 3 replicates. First factor was inoculum composition of P. chrysosporium and N. crassa (1: 1, 2: 1 and 1: 2) and second factor was inoculums doses (6, 8 and 10%). Measured variables were Crude Fiber (CF) and Crude Protein (CP). Experiment 2 was to study incubation period (7, 9, 11 and 13 days). Measured variables were DTW’s CF, CP, cellulose, hemi-cellulose and lignin. Experiment 3 was to compare nutrient content between fermented (the best treatment at experiment 2) vs. unfermented one. Measured variables were DTW’s nitrogen retention, amino acid profile, B carotene, tannin and Metabolizable Energy (ME). Result of the experiment 1, there was a very significant (p<0.01) interaction between inoculum compositions and inoculum doses in which P. chrysosporium and N. crassa inoculum composition (1:1) and 8% inoculum dose reduced CF and increased CP content. Experiment 2, incubation period of 9 days reduced CF, NDF, ADF, lignin and cellulose from 22.33, 32.49, 27.50, 15.81 and 17.62 to 8.30, 30.58, 20.26, 6.20 and 11.58%, respectively. Meanwhile increased CP and hemicellulose from 11.73 and 4.99 to 19.37 and 9.52%, respectively. Experiment 3, Nitrogen retention, B-carotene, tannin and ME content of fermented was better than unfermented DTW (42.50 vs 68.54%, 0 vs. 119.07 mg/kg, 3,76 vs 0.43% and 2586.84. vs. 2728.27 kkal/kg, respectively). Phanerochaete chrysosporium and Neurospora crassa treatment improved DTW’s amino acids profile. In conclusion, fermentation by using Phanerochaete chrysosporium and Neurospora crassa (1:1), 8% inoculum dose and 9 day incubation period was the best treatment for improving DTW’s nutrient quality.

  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: Palm Oil Sludge (POS) represents an alternative to poultry feed but its utilization is limited due to the high content of crude fiber (lignin and cellulose) and low content of crude protein. Fermentation with lignocellulolytic fungi, which include Lentinus edodes, Pleurotus ostreatus and Phanerochaete chrysosporium, produce ligninase and cellulase enzyme have been used as an approach to increase POS nutrient levels and quality. This study evaluated the nutrient content and quality of POS after fermentation using different ligninocellulolytic fungi. Methodology: Two experiments were conducted in this study. Experiment 1 was performed as a 3×3 factorial arrangement in a completely randomized design with 3 replicates. The first factor was lignocellulolytic fungi (Lentinus edodes, Pleurotus ostreatus and Phanerochaete chrysosporium) and the second factor was incubation time (7, 11 and 15 days). Subsequently, Crude Fiber (CF), Crude Protein (CP), cellulose, lignin and cellulose enzyme activity were measured. Experiment 2 compared the nutrient content of fermented (the best treatment identified in experiment 1) and unfermented POS. In this experiment, the nitrogen retention, crude fiber digestion, Metabolizable Energy (ME) and amino acid profile of POS was measured. Results: In experiment 1, it was found that Pleurotus ostreatus significantly reduced CF, cellulose and lignin levels and increased CP content as well as cellulase enzyme activity after 11 days of incubation (p<0.01) Moreover, experiment 2 showed that nitrogen retention, crude fiber digestion and ME content levels in fermented POS were higher than in unfermented POS. Fermentation also improved the amino acid profile of POS. Conclusion: An 11 day fermentation with Pleurotus ostreatus was identified as the best condition for improving the nutrient content and quality of POS.

  Background: Marigold (Tagetes erecta) Flower Extract (MFE) is a natural source of carotenoid as a feed additive in the poultry diet. Objective: This study was conducted to determine the effect of MFE as feed additive on production performances and egg quality of quail. Materials and Methods: Two hundred and seven weeks old Coturnix coturnix japonica laying quail were used in a Completely Randomized Design (CRD) with four dietary treatments: 0, 5, 10 and 15 ppm MFE in the diets with five replicates each. Variable measured were feed intake, hen-day egg production, egg weight, egg mass production, feed conversion, egg cholesterol, egg fat and yolk color. Results: It was observed that feed intake, egg production, feed conversion, egg cholesterol and yolk color were significantly affected (p<0.05) by increasing MFE content in the diet. Feed intake, hen-day egg production and yolk color achieved the best results when 15 ppm MFE was included in the diet and resulted in the lowest levels of egg cholesterol and feed conversion. Conclusion: This study shows that 15 ppm MFE in the poultry diet improved production performance and increased egg quality (reduced egg cholesterol and increased egg yolk color) of Coturnix coturnix japonica laying quail.

  Background and Objective: In certain coastal areas of Indonesia, Sargassum binderi drifts to the shore because of ocean waves and because people do not use it, becomes useless waste. This seaweed could potentially be used as feed for laying hens because certain bioactive compounds in seaweed, such as alginate, fucoidan, fucoxanthin and poly-unsaturated fatty acids (PUFA), are useful for poultry health. High salt content is a problem with using Sargassum binderi as poultry feed because it causes diarrhea and death in poultry. Therefore, the salt content of Sargassum binderi should be reduced before it is fed to poultry. The purpose of this study was to reduce the salt content of Sargassum binderi for use as feed for laying hens. Materials and Methods: The experiment was arranged in a completely randomized design with Sargassum binderi immersed in flowing river water for durations of 0, 3, 5, 7, 9, 11, 13, 15, 19, 21 and 23 h, each treatment was repeated 3 times. The measured variables were salt, crude protein, total dry matter, organic matter and ash. Results: The results showed that the different immersion durations of Sargassum binderi in flowing river water significantly affected (p<0.05) the reduction of salt, total dry matter and ash content and also significantly affected (p<0.05) the increase in organic matter and crude protein. Conclusion: The immersion of Sargassum binderi in flowing river water for 15 h was the best treatment to lower salt, total dry matter and ash and to increase the organic matter and crude protein content.

  Background and Objective: Turmeric (Curcuma domestica, Val) extract (TE) is a natural source of yellow-orange pigment and a natural source of antioxidant, antimicrobial, anti-viral, anti-inflammatory and antitumor compounds. The present study was conducted to evaluate the effect of TE as a feed additive on egg production performances and egg quality of laying quail. Materials and Methods: This study used 208 week old Laying quails. The experiment was performed in a completely randomized design (CRD) with five treatments (0, 5, 10, 15 and 20 ppm TE in drinking water) with four replicates each. The basal diet contained 20% crude protein and 2800 kcal kg–1. The parameters measured were feed intake, hen day-egg production, egg weight, egg mass production, feed conversion, egg yolk color and egg cholesterol content. Results: Increasing the TE level significantly increased (p<0.05) feed intake and hen-day egg production, egg mass production and egg yolk color but significantly decreased (p<0.05) feed conversion and egg cholesterol content. Feed intake, hen-day egg production and yolk color were optimal with the inclusion of 20 ppm TE in the drinking water while egg cholesterol content and feed conversion were lowest at this concentration. Conclusion: This study shows that 20 ppm TE increased the egg production performance and egg quality of laying quail without notable negative effects and therefore should be considered.

  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.
