Abstract

The purpose this study was to ktww the influence ofseveral processing and the storage periods offish ration added with tapioca binder on the physical characteristics offish ration. This research used a 3 x 4factorial completely randomized design with 3 replications. The data were analyzed by analysis ofvariance and the significant result would be examined by orthogonal contrast test. Factor A was processing (without treatment, AD); spraying with 5% hot water (AI) and steamingfor 45 minutes (A2), while factor B was storage periods(O, 2, 4, and 6 weeks). The parameters investigated were water activity, water content, particle size, .pellet durability, loose bulk density and compressed bulk density. The results showed that processing without treatment, spraying with 5% hot water and steaming for 45 minutes did not affect the physical characteristics of ration. However, the water content and particle size of the ration were significantly affected by processing treatments (p<O.Ol). The water content was 13.69%, 13.71% and 14.42%, while particle size of the ration processing without treatment, spraying with 5 % and spraying with 5% hot water were 0.659 em, 0.652 em and 0.658 em, repectively. The storage period highly significant influenced (p<O.Ol) physical characteristics of the ration, the value ofwater activity atoweek to 6 weeks storage periods were 0.83, 0.78, 0.76 and 0.76; water content were 14.34%, 14.82%, 13.30% and 13.30%; particle size were 0.663 em, 0.659 em, 0.651 em and 0.651 em; pellet durability were 99.95%, 99.79%, 99.73% and 99.57%; loose bulk density were 0.639 g/em3, 0.543 g/em3, 0.534 g/em3 and 0.50p g/em3; and compressed bulk density were 0.691 g/em3, 0.630 g/em3, 0.718 g/em3 and 0.712 g/em3, respectively. The results indicated that storage period decreased the physical characteristics of ration. In conclusion, the best quality offish ration was ration processed by spraying with 5% hot water and 4 weeks storage.

Abstract

The research was designed to evaluate the effect of addition of mengkudu (Morinda citrifolia) leaf extract as antibacteria of Salmonella typhimurium in drinking water during starter period (1-4 weeks) on blood profile of Japanese quail. Mengkudu leaf extract obtained from the leaves of Morinda citrifolia, which are dried, then boiled in water for 26 minutes with ratio between dried leaf and water 1:1. A completely randomized design (CRD) was used to analyze the data obtained from this research. Two hundred and fourty Day Old Quails with average body weight 7,73-8,08 g were divided into 4 treatment groups with 3 replications and 20 quails in each replicate. The treatments were R0 (quail drink was given multi-vitamin), R1 (quail drink was given 5% of mengkudu leaf extract), R2 (quail drink was given 10% mengkudu leaf extract) and R3 (quail drink was given 15% mengkudu leaf extract). The haematological parameters observed were erythrocyte number, haemoglobin level, haematocrit, and leucocyte number. The result of the research showed that the erythrocyte number, haemoglobin level, hematocrit and leucocyte number were not significantly different (P>0,05) for all treatments. Although the statistical parameters of the observations due to treatment not give significantly different results, but when viewed from the average parameters, treatment containing 15% mengkudu leaf extract (R3) gives the best results. Because it can increase hemoglobin levels, leukocyte count and blood hematocrit values were within the normal range for quail. So that 15% mengkudu leaf extract (R3) in drinking water can be used as alternative herbal feed additive instead of antibiotics

Abstract

Quality of ration can be evaluated using several methods, such as chemical, biological and physical test. Physical characteristics of ration are important aspects in feed mill industry, because they are related to handling efficiency, processing and storage. The purpose of this study was to evaluate the influence of using tapioca, bentonite and onggok binders on the physical characteristics of crumble ration. The treatmentswere commercial ration (basal ration) + 2% tapioca, basal ration + 2% bentonite and basal ration + 2% onggok. The parameters observed were water content, water activity, particle size, specific density, bulk density,compact bulk density, angle of heap, softness and impact resistance of crumble and durability. The experimental data were analysed using analysis of variance according to completely randomised design consisted of four treatments and five replications for each treatment and the differences among treatments were further tested using Duncan Multiple Range Test. The result of this experiment showed that the addition oftapioca, bentonite and onggok as binders affected(P<0.01) physical chracteristics of crumble. It affected  water content, water activity, bulk density, compactbulk density and durability. Particle size of ration with binders was significantly different from commercial ration. Ration with tapioca binder had the lowest value for water content and water activity, i.e. 9.42% and 0.84 respectively. Ration with bentonite binder had the highest value for bulk density, compacted bulk density, and durability, i.e. 0.686 g/cm3, 0.769 g/cm3, and 95%, respectively. Particlesize of ration which was binded with tapioca, bentoniteor onggok was categorised moderate compared to the commercial one.

Abstract

Biofat is a hexane extract containing several bioactive compounds with anacardic acid as the major compound. This study aimed to examine the effect of anacardic acid on rumen fermentation, especially methane and its degradation in the in vitro rumen fermentation. The study was arranged in a completely randomized block design. The treatments were control (substrate or complete feed), biofat (substrate + 0.75 uL/mL biofat), and anacardic acid (substrate + 0.75 uL/mL anacardic acid). Measured variables were total gas production, methane, pH, concentration of ammonia (NH3), dry matter degrability (DMD), organic matter degrability (OMD), and neutral detergent fiber degrability (NDFD) in the rumen. The chromatogram GC-MS analysis results indicated that the anacardic acid isolation process of the biofat produced nearly pure isolate (99.44%), and significantly decreased the production of methane by 51.21% and 39.62%, respectively. Anacardic acid degradation pattern in the in vitro rumen test showed a shifting of retention factor (Rf) value after anacardic acid being incubated with the degradation of anacardic acid occurred after 24 h of fermentation. In conclusion, anacardic acid isolated from biofat has a dominant role to reduce the in vitro methane production. Anacardic acid is very potential to be used as a methane reducing agent.

Abstract

The objective of this study was to evaluate the effect of noni (Morinda citrifolia) leaf shoot meal (NLSM) supplementation in the ration on the performances of kampong chickens as well as lipid, malondialdehyde (MDA), and fatty acid contents of meats. Two hundred and forty kampong chickens of 4 weeks old were reared until 12 weeks old. The diet treatments were R0: 0% NLSM (control), R1: 0.5% NLSM, R2: 1% NLSM, R3: 1.5% NLSM, R4: 2% NLSM, and R5: 2.5% NLSM. A completely randomized design (CRD) was used with six treatments and four replications with ten kampong chickens per replicate. The data were analyzed using ANOVA and if there were significant different, the data were further analyzed using Duncan?s Multiple Range Test. The variables measured were performances of kampong chickens as well as lipid, MDA, and fatty acid contents of meat. The result showed that cholesterol and LDL contents of meat were significantly reduced by feeding NLSM. Performance and HDL contents of meat were not significantly different for all diet treatments. In addition, feeding kampong chickens with ration supplemented with NLSM could reduce MDA, saturated fatty acids and increase unsaturated fatty acids contents of meat. It is concluded that 2.5% NLSM can be used to improve meat quality of kampong chicken as functional meat.

Abstract

The objective of this study was to evaluate the effects of sweet-potato leaves and cassava leaves inclusions into the diet containing lemuru oil on lipid metabolism of local laying ducks. One hundred and eighty laying ducks with an average body weight of 1657 g were divided into 6 groups of experimental diets with 3 replications and 10 ducks in each replication. The experiment was arranged in a 2 x 3 factorial design. The first factor was the level of sweet potato leaves consisted of 2 levels, i.e., 0% and 5%. The second factor was the level of cassava leaves consisted of 3 levels, i.e., 0%, 5%, and 10%. The variables observed were performance of laying duck, blood, meat, and egg lipid profile, as well as the relationship between the average consumption of ?-carotene with cholesterol concentration in the blood, egg, and meat of laying duck. The results showed that there was no interaction and no effect between sweet potato leaf meal (SPLM) and cassava leaf meal (CLM) on feed consumption. Different levels of SPLM and CLM gave a significant interaction effect (p&lt;0.05) on body weight gain, with the best interaction, was 5% SPLM combined with 0% CLM (26.60 g/duck). There was also a significant interaction effect between the combination of 5% SPLM and 10% CLM (p&lt;0.05) for reducing the cholesterol, triglyceride, and LDL concentrations in the blood, meat, and egg. Different levels of SPLM and CLM gave significant interaction effects (p&lt;0.05) on the fat contents of flash in laying duck. The fat content of the liver was significantly decreased by 5% treatment of SPLM (p&lt;0.05). Meat fat decreased significantly with a combination of 5% SPLM and 10% CLM (p&lt;0.05). Treatments with 5% SPLM or 10% CLM reduced blood MDA (p&lt;0.05), while treatments with 10% CLM reduced the MDA in the liver (p&lt;0.05). It can be concluded that the combination of 5% SPLM and 10% CLM in the diets was effective as a source of antioxidants to protect unsaturated fatty acids in the blood, meat, and egg of ducks based on the reduced concentrations of cholesterol, triglyceride, and LDL.
