Bioconversion is a method to increase quality of high lignocellulose-containing feedstuffs. Fermentation occurs during bioconversion is influenced primarily by length of fermentation and mineral supplementation to the medium. This study was aimed at determining the effect of these two factors on dry matter (DM), organic matter (OM), neutral detergent fiber (NDF) and acid detergent fiber (ADF), and cellulose-to-lignin ratio of cocoa pod incubated with Phanerochaete chrysosporium. Twenty four treatments containing of 4 mineral supplementations (no mineral, Ca, Mn, and Ca+Mn) and 6 different lengths of fermentation (0, 5, 10, 15, 20, and 25 days) were designed randomly to 72 fermentation glass jars in a 4x6 factorial arrangement. Length of fermentation had significant effect on all parameters measured. Mineral significantly affected changes of DM and OM, NDF and ADF content, and cellulose-to-lignin ratio, but not DM and OM content. In conclusion, supplementation of Ca to cocoa pod incubated with P. chrysosporium for 15 days contributed positively (P < 0.05) to changes of OM (13.83%) and DM (11.30%). The cellulose-to-lignin ratio of 1.34 was the optimum result of Mn supplementation for 10 days incubation.

The aim of this experiment was to evaluate the nutrient quality of cassava-based materials silage with cattle rumen liquor enzymes and Leuconostoc mesenteroides as poultry feed. The cassava material was hydrolyzed with cattle rumen liquor enzyme and incubated for 24 hours. The hydrolyzed product was added L. mesenteroides and ensiled in mini silo for 30 days. The experiment was designed in completely randomized design with 15 treatments and 3 replications. The result showed that temperature of cassava-based silage ranged from 26 to 30 oC. The flavor was sour and fresh fragrant and changed in color. Addition of cattle rumen liquor enzyme and L. mesenteroides bacteria significantly affected (P < 0.05) pH (3.73-4.86), dry matter(30.14%-43.28%), cyanide (86.71%-96.50%) and crude fiber content (0.78%-5.05%), but gave a fluctuate effect on protein content (-1.92%-2.39%). However, the treatment didnot affect dry matter losses (1.20%-2.66%). It is concluded that nutrient quality of cassava-based silage improved when it was added with cattle rumen liquor enzymes and L. mesenteroides by decreasing crude fiber and cyanide content. The best silage quality was obtained on tuber substrate and it increased protein KDUO (peel+leaves+tuber+tapioca waste) silage. Key words: cassava-based silage, cattle rumen liquor enzymes, Leuconostoc mesenteroides, nutrient quality

Leucaena (Leucena leucocephala) is a feed source which has high protein and carotenoid, but its utilization as feed was limited by the presence of mimosine (β-N-(3-Hydroxy-4 pyridone)-α amino propenoic acid as a toxin. Experiment was carried out using completely randomized design with 4 detoxification treatments and 5 replications. Detoxification treatments of leucaena leaf consisted of (1) non treated leucaena leaf, (2) steamed heating at 70 oC for 15 minutes, (3) dry heating at 70 oC for 12 h, (4) soaking with fresh water for 12 h, (5) spray with NaOH 5%, incubated for 12 h. Variables measured were mimosine and xanthophylls contents. Data were analyzed using analysis of variance and duncan multiple range test was further done to test the significant differences between means. The results showed that soaking leucaena leaf with fresh water for 12 h gave the highest reduction for both mimosine and xanthophylls contents and steamed heating at 70oC for 15 minutes had the highest xanthophylls content post detoxification. It was concluded that steamed heating at 70oC for 15 minutes was the best detoxification methods for mimosine in leucaena leaf. Key words: mimosine, Leucaena leucocephala, physical and chemical detoxification

Utilization of cocoa pod husk (CPH) as feedstuff needs pretreatment to increase its nutrients availability. Bioconversion with Phanerochaete chrysosporium changes its structure by breaking down the linkage between lignin and structural carbohydrates. This experiment was aimed to evaluate the quality of fermented CPH biomass as feed for goats. The experimental treatments i.e.: A= 30% of fresh napier grass (RG) + 50% of dried RG + 20% of concentrate; B= 30% of fresh RG + 30% of dried RG + 40% of concentrate; C= 30% of fresh RG + 30% of CPH + 40% of concentrate; D= 30% of fresh RG + 30% of fermented CPH + 40% of concentrate and E= 30% of fresh RG + 50% of fermented CPH + 20% of concentrate. The treatments were allocated in a randomized block design with three replications. Feed intake, body weight gain and ration efficiency were measured. The use of fermented CPH at the level of 30% had higher (P < 0.05) feed intake (560.33 g day-1), body weight gain (101.79 g head-1 day-1), and feed conversion (5.50) compared to other treatments. In conclusion that the use of 30% fermented CPH in the ration showed the best body weight gain and feed efficiency.

Phanerochaete chrysosporium was widely used to delignify agricultural waste product and improve biodegradation of the substrate as animal feed. The experiment was carried out to increase the use of palm oil fronds as a substitute material for napier grass through biodegradation process with P. chysosporium. A completely randomized design with four treatments and four replications was used. The treatments were ration containing 60% napier grass (R1), ration containing 40% napier grass and 20% fermented palm oil frond (R2), ration containing 20% napier grass and 40% fermented palm oil frond (R3), ration containing 60% fermented palm oil frond (R4). Fourty percent concentrate was included in all treatment rations. Parameters measured were in vitro digestibilities of dry matter, organic matter, crude fiber, NDF, ADF, NH3, TVFA, and ruminal cellulolitic bacteria. Results showed that increasing level of fermented palm oil frond in the ration reduced (P<0.05) digestibilities of dry matter, organic matter, crude fiber, NDF, ADF, N-NH3, TVFA concentration and number of ruminal cellulolytic bacteria. It is concluded that fermentation of palm oil frondwith P. chysosporium decrease lignin content by 47.79%, but increasing the fermented palm oil frond in the ration reduces nutrient digestibilities, N-NH3 and TVFA concentrations and rumen cellulolytic bacteria counts. Fermented palm oil frond up to 40% could be used as a substitute for forages in ruminant rations.

This study aims to estimate and validate the accuracy of estimated Total Digestible Nutrient (TDN) content in forages based on the chemical composition of feed. Data on nutrient composition for estimates were obtained from the BR-CORTE database consisting of 86 types of forages and primary data from observations consisting of 19 types of forages. Analysis data is used Pearson correlation, multiple linear regression, determination coefficient (R2), and root mean square error (RMSE) for estimation models, variance test (ANOVA), and T-test for validation. The results showed that forage TDN had a negative correlation with Neutral Detergent Fibre (NDF) (P <0.01) and lignin (P <0.05), but was positively correlated with Non-Fibre Carbohydrate (NFC) (P <0.01), Ether Extract (EE) and Crude Protein (CP) (P<0.01). Thus, the TDN value can be estimated from the chemical composition in the feed. The regression equation that will be used to estimate forage TDN content is TDN = 0.482 NDF + 1.538 EE + 0.699 NFC + 0.718 CP (R2=0.994). Then, this equation is validated and compared to the Hartadi’s and Wardeh’s equations. The results of the T-test showed that the TDN value estimated is non significantly different with TDN Hartadi for cattle (P>0.05). It concluded TDN value of local forage can be estimated based on this estimation models.

One method for laboratories to achieve accreditation is through proficiency testing, which relies on the availability of reference materials from specialized providers or manufacturers. This research investigates the stability of both imported and locally sourced soybean meal, which serves as control samples in animal feed laboratories. The parameters assessed in this research include water content, ash content, and crude protein levels. Statistical analyses were conducted according to the proficiency testing guidelines outlined in SNI ISO 13528:2016, focusing on homogeneity and stability assessments. The results indicate that both local and imported soybean meals are homogeneous across the tested parameters. However, the stability tests reveal differing results: local soybean meal shows instability in water content and crude protein, while its ash content remains stable. In contrast, the imported soybean meal exhibits stable water and ash content but unstable crude protein levels. In conclusion, soybean meal can be utilized as a control sample in feed laboratories for short-term applications due to its susceptibility to changes in material characteristics. Key words: homogeneity, stability, soybean meal
