Bioconversion product of shrimp waste with BLS microbes (Bacillus licheniformis, Lactobacillus spp. and Saccharomyces cerevisiae) holds digestive proteases with a great potential to be used as prebiotics for native chicken. In the present work, the ratio of liquid extract bioconversion product and binders formulated both 4:1 (T₁); 5:1 (T₂), and 6:1 (T₃) to entrap prebiotics enzymes from BLS microbes have been characterized. The trials were needed to verify contained in prebiotics from encapsulated liquid extract on quality of feed supplement. The overall results indicated that binders formulated T₂ (5:1) capsules of prebioticsᴮᴸS extract were better vehicles to deliver shrimp enzymes in native chickens. The implication of metabolizable energy and digestibility at Indonesian local chicken showed that T₂ binders formulated improve protein digestibility (80%) and metabolizable energy (3033 kcal/kg) of local chicken. Feeding trial prebiotic ᴮᴸS used at four levels (0, 0.5, 1, 1.5, or 2%) at basal feed (protein 28.22%), with one treatment of standard feed (protein 32.18%). Supplementing diets with prebiotic ᴮᴸS, especially at 1.5%, has a variety of growth-promoting effects. The results demonstrate that the observed benefits of prebiotic ᴮᴸS on low protein diets can be achieved.
