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 grain1, 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 dL1). 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.]]>Abun, T. Widjastut, K. Haetami, D.
