  This study was aimed to determine the effect of Jengkol (Pithecellobium jiringan) skin extract in ration on blood glucose, uric acid and total gut E. coli count of broiler chicken. One hundred day old commercial broiler chicks were randomly allocated to four treatment groups as T1, T2, T3 and T4 with 25 birds per treatment group replicated five times with five birds per replicate in a Complete Randomized Design (CRD). The birds in the control group (T1) were given normal basal diet without the addition of jengkol skin extract, while as other groups (T2, T3, T4) were supplemented with 0.01, 0.02 and 0.03% jengkol skin extract respectively. The blood samples were randomly collected from five birds per replicate at the end experimental period (5th week) and analyzed for the estimation of blood glucose and uric acid. The total E. coli count of gut contents was analyzed using Total Plate Count method. The results revealed that blood glucose was non-significantly (p>0.05) increased in the groups fed Jengkol at various levels when compared to the control. Further, a significantly (p<0.05) proportional decreasing trend in blood uric acid levels was found with increase in the level of dietary Jengkol, with highest reduction of 8.76±0.35 mg/dl in the group supplemented with 0.03% Jengkol (T4) compared to 11.53±1.20 mg/dl in the control group. Moreover, the total gut E. coli also decreased significantly (p<0.05) in the groups fed Jengkol in the diet (T2, T3 and T4). In conclusion, dietary inclusion of Jengkol had beneficial effect with regard to its ability in reducing the blood uric acid levels and total gut E. coli count of broiler chicken.

  Background and Objective: The processing of waste materials from the frozen shrimp industry in the form of shrimp skins and heads has the potential to be used as an alternate feed additive in poultry ration formulas. The limiting factor for the use of shrimp waste is the presence of chitin, which binds strongly to proteins, fats and minerals through β (1-4) covalent bonds so that it is difficult to digest by chicken digestive enzymes. Waste-product bio-processing can be carried out through deprotonation stages with Bacillus licheniformis as well as demineralization with Lactobacillus sp. and Saccharomyces cerevisiae to convert materials to concentrated feed nutrient products (hereafter termed Nutrient ConcentratesBLS). This biological test of Nutrient ConcentratesBLS in ration formula was conducted to determine the effectiveness of the product in the production and quality of chicken eggs. Materials and Methods: The study was carried out using domestic laying hens on a test farm. The experimental design was completely randomized; it consisted of 6 ration treatments and each treatment was replicated 4 times. The variances of the obtained data were analysed and differences between treatments were tested with Duncan's multiple range test. Results: The results of the study were obtained: (a) Nutrient ConcentratesBLS could be stored up to 8 weeks at room temperature (pH: 7.36, ammonia: 9.60%, water content: 9.67% and energy conversion: 77.36%), (b) The laying performance of domestic hens in poultry production using Nutrient ConcentratesBLS as a feed additive at a level of 2% in the ration formula was equivalent to that of the hens fed the standard ration (egg weight 44.71 g grain–1, hen-day production 51.79% and ration efficiency 35.49%) and (c) The quality of chicken eggs from hens fed Nutrient ConcentratesBLS was better than that of hens fed the standard ration (shape index: 79.34, albumin index: 0.20, Haugh-unit: 94.11, yolk index: 0.37, yolk colour: 9.00 and egg cholesterol levels: 96.45 mg dL–1). Conclusion: Nutrient ConcentratesBLS, made from shrimp waste bioprocessed by Bacillus licheniformis, Lactobacillus sp. and Saccharomyces cerevisiae, can be used as feed additives in the feed formula of domestic laying hens. To support the production and quality of chicken eggs, Nutrient ConcentratesBLS can be used up to levels of 2% in the feed formula.

  Background and Objective: Improving the quality of waste containing high levels of chitin through bioprocesses that utilize the services of the microbes Bacillus licheniformis, Lactobacillus sp. and Saccharomyces cereviseae can generate a high-quality product that can meet the requirements of domestic chickens. The objective of this study was to determine the optimal bioprocessing conditions to make a nutrient concentrate, as well as to describe its biological quality for the domestic chicken. Materials and Methods: This study utilized experimental methods in the laboratory that consisted of a completely randomized design with six treatment rations (R0, R1, R2, R3, R4 and RS) that were replicated five times. The data were subjected to analysis of variance and the differences between treatments were tested by Duncan's multiple range test. Results: Bioprocessing shrimp waste with Bacillus licheniformis for two days, followed by Lactobacillus sp. for two days and finally, Saccharomyces cereviseae for two days resulted in the best nutrient content (48.50% crude protein, 7.81% crude fat, 7.57% calcium and 3.14% phosphorus), The metabolizable energy value and protein digestibility of the nutrient concentrate for the domestic chicken were 2613.90 kcal kg1 and 72.91%, respectively. Conclusion: Processing shrimp waste for poultry feed, especially for domestic poultry, can be achieved through multilevel fermentation technology that uses microbial services to produce a nutrient concentrate with good chemical and biological qualities.
