  Background and Objective: The province of West Sumatra is rich in various species of shellfish that live in salt water and fresh water bodies, including the ocean, estuaries, lakes and rivers. This study aimed to evaluate the physical properties and nutritive values of shell meals produced from different shellfish species living in various habitats. Materials and Methods: Samples of shellfish were collected from 12 locations in 4 different water body types: Lakes, rivers, estuaries and oceans. Shell parts were separated, dried and weighed. The dried shells were then ground or subjected to open-air burning to produce 3 meal products: Raw coarse meal, raw fine meal and roasted meal. The products were weighed and analyzed for physical properties (bulk density, angle of response and particle size) and content of crude ash, Ca and P. The nutritive values of the meals were evaluated by mixing 3% shell meal with basal diet that was fed to 200 laying quails in a completely randomized design. There were four dietary treatments: Control diet (P0), basal diet+3% roasted meal (P1), 3% raw fine meal (P2) and 3% raw coarse particles (P3). The quail were divided into 20 experimental units of 10 birds each, so that each treatment consisted of 5 replications. Parameters measured include feed intake, egg production, feed conversion ratio (FCR) and egg shell quality. Results: The dried shells represented between 47 and 56% of the total body weight of the shellfish, with lake mussels having the highest percentage of shell parts (p<0.05). Raw coarse ground meal had the highest percentage of meal yield (98.7%), followed by raw fine meal (95.8%) and roasted meal (86.8%) (p<0.01). Raw coarse meals had higher bulk density and lower angle of response due to the higher percentage of large particles (p<0.05). The Ca content of roasted meal was significantly higher (p<0.05) than that of the raw meals. There was no significant effect of the different shell meal products on feed intake, egg production or FCR. However, quail fed a diet containing raw coarse ground shell (P3) had significantly better egg shell quality (p<0.05) than those fed the control diet (P0), P1 or P2. Conclusion: Shell meal that had coarse particles showed the best physical properties and nutritive values.

  This study aims to determine the best processing methods of palm leaves that can improve nutrient and digestibility as ruminant feed. An in vitro study was conducted from June, 15th 2012 until September, 20nd 2012. Palm leaf samples were analyzed using Proximate and Van Soest method in Laboratory of Ruminant Nutrition of the Faculty of Animal Husbandry, University Andalas, Padang. This study is an experimental study that uses a completely randomized design with 5 (five) treatment and 4 (four) replications. Treatment consists of: A = control (no treatment), B = physical processing (steam), C = chemical processing (ammoniation), D = biological treatment (ensilage) and E = combination of physical-chemical properties (steam-ammoniation). Data were analyzed using analysis of variance (ANOVA). Differences between treatments were tested by Duncan's Multiple Range Test (DMRT). The results showed that treatment of C = chemical processing palm leaf (ammoniation) provides nutrients and better digestibility than some other palm leaf processing methods with its nutritional value was as follow: dry matter (41.51%), organic matter (86.56%), crude protein (14.65%), NDF (53.22%), ADF (40.76%), cellulose (19.67%), hemicellulose (12.46%), lignin (9, 91%). In vitro digestibility were as follow: dry matter (36.57%), organic matter (43.88%), crude protein (47.24%), NDF (32.65%), ADF (23.70%), cellulose (30.30%), hemicellulose (51.94%). Rumen fluid characteristics: pH (7.10), VFA (135.55 mM) and NH3-N (58.72 mg/100 ml).

  This study aims to obtain the best combination of mineral S and P levels on ammoniation palm leaves in order to improve the digestibility of palm leaves as ruminant feed. The study was conducted starting on June 17, 2013 until October 17, 2013. Ammoniated palm leaf samples supplemented with mineral sulfur and phosphorus are subjected to Proximate and Van Soest analysis in Ruminant Nutrition Laboratory of the Faculty of Animal Science Andalas University, Padang. The method used in this study is an experimental method using a factorial randomized block design (3x3) with 3 replications. The first factor is the treatment of mineral Sulfur with 3 levels: S0 = 0.0%, S1= 0.2% and S2 = 0.4% of DM. The second factor is the mineral P in 3 levels, ie P0 = 0.0%, P1 = 0.27% and P2 = 0.54% of the DM. Parameters measured were dry matter digestibility (IVDMD) organic matter, crude protein, NDF, ADF, cellulose, hemicellulose and characteristic rumen fluid: pH of the rumen fluid, the levels of VFA, NH3-N content of rumen fluid.

  The objectives of this study was to evaluate the potential of palm fruit by-products as feed supplement to increase weaned calves performance. Solid ex-decanter were combined with multi mineral and utilized as feed supplement to form a lick block. Ten weaned calves 6 months old (122.34±20.25 kg) were randomly categorized into 2 groups. Control weaned calves receive no Solid Ex-Decanter Multi-Nutrient Block (SEDMB) supplementation and treated calf were given continuously. The experiment was conducted at rural farming areas in Darmasraya and calves fed total mix ratio formulated with palm fruit by product based. Measured parameter were daily weight gain (DWG), body condition score (BCS), feed consumption, feed conversion, in vivo dry matter and organic matter digestibility. The treatment were significantly different (p<0.05) on daily weight gain, body condition score and feed conversion but did not significantly different (p>0.05) on feed consumption, dry matter and organic matter digestibility. SEDMB supplementation on weaned calves performance of Simbrah Breed showed the effectiveness of feed consumption.

  Objective: This experiment was carried out to determine the effects of various levels of concentrate and oil-palm fronds (OPF) on nutrient digestibility and apparent mineral bioavailability in beef cattle. Materials and Methods: Fifteen Simmental cattle were allocated to three experimental diets in a random block design. Dietary treatment 1 (diet 1) contained 40% concentrate and 60% OPF, dietary treatment 2 (diet 2) contained 50% concentrate and 50% OPF and dietary treatment 3 (diet 3) contained 60% concentrate and 40% OPF. The concentrate consisted of rice bran, tofu waste and ex-decanter solid waste from palm-oil processing, no mineral supplement was given in this study. Results: The results of the study showed that the digestibility of dry matter, crude fiber, crude protein, Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF) and cellulose were significantly higher (p<0.01) in cattle given 60% concentrate and 40% OPF (diet 3). The apparent bioavailability of both macro and micro-minerals in diet 3 was significantly higher (p<0.01) than in the other diets. The apparent bioavailability of calcium (Ca), magnesium (Mg), phosphorus (P) and sulfur (S) in diet 3 were 46.5, 48.9, 53.7 and 52.1%, respectively, while the apparent bioavailability of iron (Fe), manganese (Mn), cobalt (Co) and zinc (Zn) were 38.9, 30.7, 36.6 and 41.5%, respectively. These results indicated that increasing the amount of OPF up to 60% as a main source of forage in the rations of beef cattle reduced the nutrient digestibility and apparent bioavailability of minerals. The diet containing 60% OPF resulted in a greater deficiency of minerals, whereas increasing the level of concentrate from 40-60% significantly reduced the deficiency of minerals (p<0.01). Furthermore, the apparent bioavailability of minerals was low overall and all three experimental diets were deficient in minerals, showing that supplementation of certain minerals is needed to support optimum production of beef cattle. Conclusion: Based on these results, it could be concluded that feeding beef cattle with 60% concentrate and 40% OPF results in higher digestibility of nutrients and improved bioavailability of minerals and reduces deficiency of minerals.

  Background and Objective: Leaf waste from palm oil plants has not been widely utilized by farmers due to the low biological quality of the palm leaf midrib. Efforts to optimize the utilization of waste-derived feed include physical, chemical or biological processing or a combination of those techniques. This research was conducted to determine the best palm leaf processing method to increase the nutrient content and digestion of the palm leaf midrib. Materials and Methods: This study used completely randomized design with 5 treatments and 4 replications. Treatments were = A: Control (without treatment), B: Physical processing (steam), C: Chemical treatment (ammonia), D: Biological treatment (ensilage) and E: Chemical-physical combination (steam-ammonia). The parameters that were measured included the nutrient content, dry matter digestibility, organic matter, crude protein, in vitro fibre fraction and rumen fluid characteristics. Results: The processing of oil palm leaf pole with ammonia (treatment C) resulted in better nutrient contents and in vitro digestion for cut palm leaves than other treatment methods (p<0.05). Leaves in treatment C had the following nutrient contents: Dry matter (40.51%), organic matter (84.25%), crude protein (13.75%), neutral detergent fibre (NDF) (54.76%), acid detergent fibre (ADF) (42.54%), cellulose (20.77%), hemicellulose (12.22%) and lignin (10.74%). In vitro digestion resulted in the following nutrient contents: Dry matter (34.53%), organic matter (41.65%), crude protein (45.32%), NDF (30.71%), ADF (24.28%), cellulose (31.39%) and hemicellulose (51.78%). The rumen fluid characteristics were as follows: pH (7.02), VFAs (135.93 mM) and NH3-N (58.90 mg/100 mL). Conclusion: Treating cut palm leaf poles with ammonia results in better nutrient contents and in vitro digestion than physical processing (steam), biological treatment (ensilage) or a combination of physical and chemical processing (steam-ammonization).
