Evaluation of chemical composition and nutritive potential of oil palm slurry fermented with cassava peel as feed for livestock

In this study, elephant grass ((Pennisetum purpureum) was ensiled with varying levels of poultry dropping and cassava peel (CSP). Silage characteristics and chemical composition of the silage mixtures were determined in the laboratory while preferences of West African Dwarf (WAD) goats for the mixtures were assessed using eighteen (18) WAD goats. The treatments were: T1: P. purpureum (60%), poultry dropping (40%), dry cassava peel (0%); T2: P. purpureum (60%), poultry dropping (30%), dry cassava peel (10%); T3: P. pupureum (60%), poultry dropping (20%), dry cassava peel (20%); T4: P. purpureum (60%), poultry dropping (10%), dry cassava peel (30%); T5: P. purpureum (60%), poultry dropping (0%), dry cassava peel (40%) and T6: P. purpureum (100%). All the mixtures formed good silage, except the silage with the highest proportion of poultry dropping (T1) and acidity (pH) ranged from 6.75 to 3.80 (T1 and T5 respectively) while colour varied from pale to light green with dark brown and white speckles as proportion of cassava peel in the silage mixture increased. All silages had firm texture with pleasant and slightly alcoholic smell. Dry matter (DM) content of silage increased as proportion of cassava peel in the mixture increased while crude protein (CP) and (NDF) reduced. DM, CP and CF varied from 27.00 to 54.00%, 8.46 to 10.72% and 28.52 to 60.52 %, respectively. The preference by goats was 11.22, 20.44, 20.71, 21.78, 22.56 and 32.28% for T5, T4, T6, T3, T2 and T1 respectively. These results revealed that the silage properties, chemical composition and acceptability of elephant grass silage by WAD goat were enhanced by the addition of cassava peel and poultry dropping to elephant grass

Pasture Legumes

Pasture legumes is a very high quality of forage. The limited land is the problem of its development. Integration with oil palm plantations is one of the potentials for its development. This study was aimed to investigate the productivity of several legumes (Arachis glabrata, Stylosanthes guianensis, Clitoria ternatea, and Chamaecrista rotundifolia) as forages and cover crop. The potential tests were conducted in oil palm area of 4608 m2, in a complete block design with four treatments (legume species) and three replications. Parameters observed were: Legum production, leaf/stem ratio, chemical composition of legume, concentration of N, P in the soil, microbes in the soil, leguminous digestibility and palm fruit production. Results showed that the highest legume production (DM) was (P<0.05) in the species of Clitoria ternatea (16.15 tons ha-1year-1), the highest leaf/stem ratio (P<0.05) was in the Arachis glabrata (2.09). The chemical composition (DM) did not differ (P>0.05) ranged from 33.75 to 35.75%, the organic matter (OM) varied greatly (P<0.05) the highets was in Clitoria ternatea. The highest Crude protein (P<0.05) was in Clitoria ternatea 17.84%. NDF concentrations did not differ (P>0.05). The lowest ADF concentration (P<0.05) was in Chamaecrista rotundifolia. The concentration of N in the soil indicated that early year of activity was similar (average 0.10%), at the end of activity increased (P<0.05) in treatment Stylosanthes guianensis (0.16%). The highest population of N-fixation bacteria of 1.76x109 and phosphate solvent of 9.8x105 were in the treatment of Clitoria ternatea. Production of fresh fruit bunches of the palm was relatively similar (P>0.05) ranged from 16.52-19.21 tons ha-1year-1. It is concluded that Clitoria ternatea is the best species of legume tested as forage and cover crop in oil palm plantations.

The Relationship

The investigation of the antimicrobial and antioxidant activities of palm kernel oils extracted from varieties Dura (oil D) and Tenera (oil T) of oil palm (Elaeis guineensis Jacq.) and the relationship to their chemical composition were carried out in this study. The results obtained show that oil D had the greatest antimicrobial activity. The analysis of gas chromatographic coupled to mass spectrometry (GC-MS) showed that this oil D contained in addition to the lauric acid, the undecylenic acid which both possess antimicrobial activity. This undecylenic acid was not identified in oil T. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay and the Fe3+ reduction test (FRAP) used to evaluate the antioxidant activity of the palm kernel oils had showed that oil T had the greatest antioxidant activity with a concentration inhibiting 50% of the reaction (IC50%) of 750 mg/L. It was also noted that, this oil T had also the highest contents in polyphenols, α-tocopherol and sterols with predominance of β-sitosterol. Moreover, the β-sitosterol is known to possess a regulatory role of the immune system.The findings of this study provide thus, useful information which may help customers to make the best choice in the consumption of these oils.

Abstract Oil palm fibers have been developed as reinforcement in the composite. These fibers can be produced from fruit, trunk, and frond of oil palm. In this review, the oil palm fruit fiber for reinforcing composite was focused. Oil palm fruit fibers consist of empty fruit bunch (EFB) and mesocarp fruit (MF) fibers. The chemical composition and characteristics of oil palm fruit fiber are described. Furthermore, the mechanical properties of the composite are reported to be related to the surface treatment of EFB and MF fibers. Applications of such fiber composite are included in this review. From some researches, the surface treatment methods for MF and EFB fibers as reinforcement composite was conducted with using alkali, silane, acryilic acid, acetic anhydride, hydogen peroxide, microwave, and superheated steam. The effect of these surface treatments on oil palm EFB and MF fibers displayed the improvement of the mechanical properties (tensile, flexural and impact strengths) of the composite due to enhance the interface adhesion between fiber and matrix after treatment of fibers.
