Abstract

Frozen shrimp processing waste has the potential to be used as feed, but the characteristics of the shrimp shells need to be improved so that they can be digested. Fermentation using three types of microbes in stages has been studied, to determine the optimal processing time that yields proximate values and protein digestibility of shrimp waste concentrate. Completely randomized design (CRD), 3 treatments and 7 replications, conducted with treatments of shrimp waste bioconversion in stage over time, T1 = Bacillus licheniformis (Bl.) 1 day + Lactobacillus sp. (Ls.) 1 day; + Saccharomyces cerevisiae (Sc) 1 day; T2 = Bl. 2 days + Ls. 2 days + Sc = 2 days; T3 = Bl. 3 days + Ls. 3 days + Sc = 3 days. Product of shrimp waste bioconversion was used as a nutrient concentrate in dietary of local poultry (CP 15%, ME 2750 kcal/kg). The best proximate analysis value showed that each stage overtime two days of bioconversion with Bacillus licheniformis, followed by Lactobacillus sp. and finally fermented by Saccharomyces cerevisiae. The proximate analysis resulted that the Crude Protein of product bioconversion was 48.5%. Extract ether, Calcium and Phosphorous contents respectively were 7.81%, 7.57% and 3.14%. The best value of digestibility of protein feed containing bioconversion product of concentrations of local poultry was 72.91%.
