Abstract:
Shrimp shells and heads are waste materials that still contain protein but are constrained by the presence of chitin (15-20%) so they are difficult to digest by digestive enzymes. The research was conducted at the Faculty of Animal Husbandry, Padjadjaran University, Jatinangor, Sumedang. This study aims to obtain the optimum processing time at each stage of the bioprocess of shrimp waste with different microbes on the nutritional content and protein digestibility of the product as a concentrate of feed nutrients in native chickens. This research was conducted as an experiment in a laboratory, using a completely randomized design (CRD), 3 treatments, and 7 replications. Data were analyzed with variance and Duncan's Multiple Distance Test. Treatment of shrimp waste bioprocess is carried out in stages (W) W1 = Bacillus licheniformis (Bl.) 1 day + Lactobacillus sp. (Ls.) 1 day; + Saccharomyces cerevisiae (Sc) 1 day; W2 = Bl. 2 days + Ls. 2 days + Sc = 2 days; W3 = Bl. 3 days + Ls. 3 days + Sc = 3 days. Shrimp waste bioprocess products were used as a nutrient concentration in native chicken feed (CP 15%, ME 2750 kcal/kg). The best nutritional content showed a processing time of two days at each stage of the bioprocess with deproteination using Bacillus licheniformis, followed by demineralization by Lactobacillus sp. and finally fermented by Saccharomyces cerevisiae for 2 days each. The crude protein content of bioprocesses products is 48.5%, while crude fat, calcium, and phosphorus are 7.81%, 7.57%, and 3.14%, respectively. Protein digestibility is the best product, the concentration of nutrients in native chicken feed is 72.91%.
