Effect of fermented shrimp shell supplementation of low protein diet on the performance of Indonesian native chicken

Abstract

A high-quality diet during the growth period is necessary to support poultry performance. Shrimp shell fermentation with Bacillus licheniformis, Lactobacillus sp., and Saccharomyces cerevisiae (SSFBLS) can improve the quality of low protein diet in Indonesian native chickens. This study was conducted to evaluate the effect of SSFBLS supplementation in a low protein diet on the growth performance of Indonesian native chickens. Three hundred native chickens were assigned to six treatments with five replications using a completely randomized design. The treatments consisted of a low protein diet formula (15%) with SSFBLS levels 0, 5, 10, 15, and 20% and RS as a high protein recommended feed (18% protein). The evaluation results showed that the use of SSFBLS supplementation of 10% in low-protein diets, in (P < 0.05) improved body weight gain, feed conversion, and feed efficiency than at 0-5%, and was similar to the high-protein diet. SSFBLS 20% increased the protein content of meat and reduced cholesterol levels of meat and ammonia excreta. Revenue on feed costs was highest at 10% SSFBLS. The added value of SSFBLS, which contains nutrients and chitosan, can be used as an ingredient in feed formulas to support the growth performance of Indonesian native chickens.
