  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: Palm leaf is a by-product of palm plantations that can be used as a feed alternative. Ammoniation is a potential approach to increase the digestibility of palm by-products. Objective: This study aimed to determine the cassava leaf meal supplementation level as a source of branched chain amino acids for ammoniated palm leaf enriched with sulphur (S) and phosphorus (P) minerals as feed for cattle as examined in vitro . Materials and Methods: Samples of S and P mineral-enriched ammoniated palm leaf supplemented with cassava leaf meal were analyzed for proximate composition. In this study, ammoniated palm leaf samples enriched with S (0.40%) and P (0.27%) were treated with several cassava leaf meal supplementation levels. This study used a randomized block design with 6 treatments and 4 replications. The treatments tested were 6 levels of cassava leaf meal (0, 5, 10, 15, 20 and 25% dry matter). Dry matter, organic matter, crude protein, Neutral Detergent Fibre (NDF), Acid Detergent Fibre (ADF), cellulose, hemicellulose and rumen fluid characteristics (pH, VFA concentration and NH3-N level) were evaluated. Results: The results showed that mineral (0.4% S and 0.27% P) and cassava leaf meal (5% of dry matter) supplementation exhibited higher digestibility compared to other treatments. This supplementation formula resulted in the following in vitro digestibility characteristics: dry matter (55.56%), organic matter (59.83%), crude protein (55.34%), NDF (56.99%), ADF (50.01%), cellulose (60.78%) and hemicellulose (71.35%). The rumen fluid characteristics of this formula were as follows: pH (6.70), VFA (129.89 mM) and NH3-N (15.84 g/100 mL). Conclusion: Sulphur and P mineral-enriched ammoniated palm leaf supplemented with cassava leaf meal had significantly increased digestibility and rumen fluid qualities. Treatment with 5% cassava leaf meal produced the highest digestibility and rumen fluid characteristics.

  Objective: This study was designed to explore the effects of supplementing processed leaf-based palm leaf rations with minerals [sulfur (S) and phosphorus (P)] and cassava flour on the optimization of bioprocess in the rumen and beef cattle growth performance. Materials and Methods: Simmental beef cattle were divided into 5 treatments and 4 replicates. The treatments consisted of A = Field grass+concentrate (60%: 40%, used as the control), B = Palm frond ammoniation + concentrate (60%: 40%), C = B + mineral supplementation S (0.4%) and P (0.27%), D = B + cassava flour (5%) and E = C + cassava flour (5%). The consumption of dry matter rations, dry matter digestibility, weight gain and feed efficiency was evaluated. Results: it is observed that the treatments had significantly different effects on Simmental cattle growth performance (p<0.05). The average dry matter ration consumption ranged from 11.25-11.76 kg/head/day, average dry matter digestibility ranged from 52.28-62.01%, average weight gain ranged from 0.84-1.01 kg/head/day and average feed efficiency ranged from 7.39-8.59%. Conclusion: Ammoniated palm oil leaves supplemented with the minerals [S (0.4%) and P (0.27%)] and cassava starch flour (5%) can replace 100% of the grass in beef cattle rations and resulted in better growth performance than was observed for control rations (grass feed) in terms of weight gain.

  Background and Objective: Utilization of plantation waste, such as palm stems, is still limited due to its high lignin content and low digestibility. Therefore, it is necessary to apply technology to improve feed quality in terms of both nutritional value and waste digestibility. Such technology will ultimately improve the quality of animal feed. White rot fungi, such as the basidiomycete Pleurotus ostreatus (P. ostreatus), can degrade lignin by using lignases, which include lignin peroxidase, manganese peroxidase and laccase. Materials and Methods: The study was conducted in the Nutrition Laboratory of Andalas University. This study used completely randomized design with factorial pattern. Factor A is P. ostreatus dose (3, 5 and 7%) and factor B is the fermentation time (1, 2 and 3 months). Results: The results showed that fermentation of palm stem with P. ostreatus for 3 months could decrease NDF content up to 11.03%, ADF content up to 9.65%, hemicellulose content up to 1.39% and lignin content up to 7.24%. Conclusion: The dose of P. ostreatus and the fermentation time did not interact significantly. However, the fermentation time of 3 months significantly (p<0.05) decreased the contents of NDF, ADF, hemicellulose and lignin in palm midribs and can be used to improve the quality of animal feed ingredients, especially feed used for ruminants.

  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).
