Abstract This research aimed to reduce the lignin content and increase the nutrients content of sugarcane shoots as forages for a ruminant. This research used an experimental method using a completely randomized design (CRD) in factorial patterns, whereas A factor was a type of fungi (Pleurotus ostreatus and Aspergillus oryzae), and B factor was biodelignification time (14. 21 and 28 days). The variables observed in the experiment were laccase enzyme activity, Crude Protein (CP) content, and the percentage of lignin decreased. The research results showed that biodelignification using Pleurotus ostreatus fungi for 28 days resulted: 1,62 U/ml of laccase enzyme activity, 9.23% crude protein content, and 12.83 % of lignin decreased. From this research, the best treatment for bio-delignification of sugarcane shoots was with Pleurotus ostreatus fungi for 28 days, producing the best sugarcane shoots with 9.23 % of crude protein 12.83% of lignin decreased.

ABSTRACT This study aimed to evaluate the effect of different Clitoria fairchildiana tree shading levels on the Tanganyika grass (Megatyrsus maximus Jacq. cv. Tanganyika) chemical composition, in summer I (2011/2012), spring (2012) and summer II (2012/2013) seasons. For this purpose, an experiment was conducted in a completely randomized design with four treatments (shading levels) and five repetitions at Seropédica, state of Rio de Janeiro, Brazil. The following variables were evaluated: dry matter (DM), crude protein (CP), neutral detergent (NDF) and acid detergent (ADF) fiber, neutral (NDIP) and acid (ADIP) detergent insoluble protein, lignin (LIG) and mineral matter (MM) contents. Data were analyzed by PROC MIXED SAS®, with repeated measures in time, and treatment means compared by Tukey’s test (P<0.05) or by PROC REG (P<0.05 for regression analysis. There was a significant interaction between season and shading level for DM, CP, NDF, ADF, NDIP, ADIP and MM contents (P<0.05). Lignin content was only influenced by shading level (P<0.05). The DM, NDF, ADF and lignin contents were reduced by shading increase while CP, NIDP and MM contents were increased. Higher ADIP contents were found only in the spring. The increase in Clitoria fairchildiana tree shading improves the chemical composition of Tanganyika grass forage during summer season.

The rice straw has potential to be used as an alternative ruminant feed. However, it has limiting factors i.e low crude protein, high crude fiber, lignin, cellulose, and silica content. To overcome the limiting factors, immersion in a solution of alkaline (lime) or fermentation by using inoculum microbial cellulolytic and lignocellulolytic (Trichoderma mutan AA1 and Aspergillus niger.). The research method was experimental, with four treatments and repeated five times. Completely randomized design was used and if there are differences among treatments a further test with DMRT was carried out (level 1 % and 5 %). These treatments were T0: The rice straw without t fermentation; T1: Fermented with A. niger; T2: Fermented with T. mutan AA1; T3: Fermented with a combination A. niger and T. mutan AA1. The results showed that the rice straw fermented with A. niger and T. mutants AA1 very significantly increased the cellulose and decreased lignin content. The highest cellulose reached on T3 (20.297 %) followed by T2 (18.191 %), T1 (17.712 %) and T0 (16.747 %), respectively. While the lowest content of lignin reached on T3 (14.793 %), followed T2 (26.063 %), T1 (26.421 %) and T0 (38.164 %).

The experiment was conducted to study the comparison on biomass production of fodder germplasm. Para (Brachiaria mutica Stapf.), German (Echinochloa crusgalli L.) and Dhal (Hymenachne pseudointerrupta C. Muell) grasses were cultivated in a completely randomized design (CRD). The whole area was divided into nine plots. The area of each unit plot was 6 m x 6 m. Number of cuttings were 16,000 /hectare where Plant to Plant distance was 16 cm and row and raw distance was 16 cm. Equal amount of organic and chemical fertilizer were applied in all cutting. The fodders were first harvested after 60 days of planting, second and third after successive 60 days of re-growth. The findings of the study showed that fresh biomass (p<0.01) and dry biomass yield (p<0.05) of three fodder germplasm differed significantly. Crude protein and organic matter yield were significant (p<0.01) only in the second cutting. German grass was showed significantly higher in CP and OM yield (p<0.01) at second cutting than other grasses. However, no significant effect on plant height was observed among three grasses. From the above findings it may be concluded that among the three fodder germplasm, German fodder showed best result in respect of biomass production.

Abstract. Pazla R, Jamarun N, Agustin F, Zain M, Cahyani NO. 2020. Effects of supplementation with phosphorus, calcium and manganese during oil palm frond fermentation by Phanerochaete chrysosporium on ligninase enzyme activity. Biodiversitas 21: 1833-1838. The objective of this study was to evaluate the effects of supplementation with phosphorus (P) in combination with calcium (Ca) and manganese (Mn) during oil palm frond (OPF) fermentation by Phanerochaete chrysosporium on ligninase enzyme activity and lignin degradation. This study was carried out using a randomized complete design with 3 treatments (addition of P, Ca and Mn) and 5 replicates. The following treatments were performed: T1 (P 1000 + Ca 2000 + Mn 150 ppm), T2 (P 1500 + Ca 2000 + Mn 150 ppm), and T3  (P 2000 + Ca 2000 +Mn 150 ppm). The data were subjected to an analysis of variance (ANOVA), and differences between treatment means were tested using Duncan's multiple range test (DMRT). The parameters measured were as follows: lignin peroxidase (LiP) activity (U/mL), manganese peroxidase (MnP) activity (U/mL), crude protein (CP) content (%), crude fiber (CF) content (%) and the decrease in lignin (%). The results revealed a significant increase in LiP activity and CP content and a decrease in the lignin content (p<0.05) by the addition of P in the T3 treatment. However, the treatment nonsignificantly increased (p>0.05) MnP activity and significantly decreased (P<0.05) the CF content. In conclusion, supplementation of the OPF fermentation process with P 2000, Ca 2000, and Mn 150 ppm resulted in the highest ligninase enzyme activity and in decreased lignin content.

The objective of this study is to evaluate the influence of five feed restriction programs (FRP) on broiler performance and carcass yield. 425 Cobb 500® broilers were distributed in a completely randomized design with five FRPs and five replicates with 17 broilers. The FRPs were: Program 1 (P1): consumption ad libitum (AL) of control diet from 14 to 42 days; P2: quantitative restriction (QTR) of 10% of AL consumption from 14 to 28 days and AL consumption from 29 to 42 days; P3: AL consumption from 14 to 28 days and QTR from 29 to 42 days; P4: qualitative restriction (QLR) of 10% of the level of crude protein and essential amino acids from 14 to 28 days and AL consumption from 29 to 42 days; and P5: AL consumption from 14 to 28 days and QLR from 29 to 42 days. The broilers of the AL treatment gained more weight (p≤0.01), but had a similar FCR (P>0.05) compared to broilers submitted to QTR from 29 to 42 days. In addition, broilers fed QTR from 14 to 28 days presented a lower FI and a better FCR (p≤0.01) in relation to broilers fed QLR of 14 to 28 (P4) and 29 to 42 days (P5). The broilers fed QTR of 14 to 28 days diet presented a similar FCR as broilers fed AL. The 10% reduction in AL consumption of 14 to 28 d is a viable economical alternative to feed broilers up to 42 days of age.

The growth performance and blood profile of forty-eight (48), six (6) weeks old rabbit bucks of cross (Chinchilla and New Zealand White) were assessed for 10 weeks. The bucks were allotted on weight equalization basis in a 2 x 4 factorial experimental layout composed of 24 rabbits into steel hutches and wooden hutches each and on four (4) varying levels (0, 5, 10 and 15 mL/litre of water, respectively) of oyster mushroom (Pleurotus ostreatus Jacq ex fr.) extract. Six (6) bucks were assigned to each treatment group and replicated three times with two (2) bucks per replicate in a Completely Randomized Design. The phytochemicals of the oyster mushroom extract showed that 9,12-Octadecadienoic acid (Z, Z)- methyl ester was the most abundant. Results showed that the feed conversion ratio was significantly (P<0.05) best (6.08) in bucks reared in wooden cage and administered 15 mL oyster mushroom extract. Significantly (P<0.05) highest triglycerides (81.00 mg/dL) was obtained in bucks on steel hutch and on 5 mL oyster mushroom extract and lowest (55.00 mg/dL) in bucks on steel hutch and on 10 mL oyster mushroom extract. The lowest (P<0.05) lymphocytes (59.00%) were recorded in bucks on wooden cage and administered 10 mL oyster mushroom extract. It was concluded that oyster mushroom extract up to 15 mL/litre of water administered in either steel hutch or wooden hutch did not impair the growth performance and blood profile of rabbit bucks.

The objective of this experiment was to determine the effects of feeding rabbits with Maxigrain® (M) enzyme supplemented Gliricidia sepium leaf meal (GLM) on their physiology, performance characteristics, and nutrients digestibility. Twenty weaned rabbits of mixed sexes, 5-6 weeks old, were randomly allotted to five dietary treatments including 0 g M which was soybean without M (control) and GLM supplemented with M at 50, 100, 150 and 200 g M per kilogramme of GLM. There were four rabbits per treatment and one rabbit as replicate in a completely randomized design. There were no significant (p > 0.05) treatment effects in all physiological and performance indices as well as those of crude fat, fibre and NFE digestibilities. There were variations (p < 0.05) due to the treatment effects on dry matter, crude protein and ash digestiblities. This implies that the feeding of soft faeces directly from the caecum called coprophagy mechanism in rabbits has its concomitant nutritional benefits. This advantageous benefit can enable rabbit to effectively and efficiently utilize forage or forage-based diet with or without enzyme supplementation.
