Abstract:
Shrimp waste contains protein that binds to chitin and is difficult to digest by poultry, so it is necessary to carry out a fermentation process using Bacillus licheniformis, Lactobacillus sp., and Saccharomyces cerevisiae. This study was conducted to determine the Effect of using fermented shrimp waste products that resulted in the optimal conversion of meat protein, carcass weight, and abdominal fat in native chickens. The method used was a completely randomized design with five feed treatments, namely, feed without fermented shrimp waste (R0), feed fermented shrimp waste with 5% (R1), 10% (R2), 15% (R3), and 20% (R4). Experimental feed was given to 125 native chickens, divided into 25-unit cages, and reared up to 8 weeks of age. The observed variables were feed and meat protein conversion, carcass weight, and abdominal fat weight. The study results concluded that fermented shrimp waste did not affect the value of meat protein conversion and abdominal fat weight. The use of 5-10% fermented shrimp waste in feed produces optimal native chicken carcass weight.
