The shell and head of shrimp is a waste material whose protein content is constrained by its content of chitin (15-20%) making it difficult to digest. The objective of this research was to determine the optimum time required for different microbes bioprocess shrimp waste in order to improve nutrient availability, protein digestibility, and metabolizable energy of these materials in native chickens. Experiments were conducted using a completely randomized design with three microbial treatments and bioprocessing times. Data were statistically analyzed for variance using a Duncan’s Multiple Range test. Shrimp waste materials were treated with each microbe sequentially over time (W) as follows: W1, Bacillus licheniformis (Bl) + Lactobacillus sp. (Ls.) + Saccharomyces cereviseae (Sc), each for 1 d; W2 = Bl+ Ls+ Sc, each for 2 d; W3 = Bl+ Ls+ Sc, each for 3 d. Bioprocessed products of shrimp waste materials were used as a nutrient concentrate in diets of native chickens (crude protein). The optimal crude protein content at W2 of the bioprocessed product was 48.5%, while extract ether, calcium, and phosphorous levels were 7.81%, 7.57%, and 3.14%, respectively. The highest protein digestibility obtained from the best nutrient (W2) with value 72.91%; the best of metabolizable energy of these materials was 2613.90 kcal/kg.
