The digestibility value of local chicken rations fed with feed containing fermented catfish waste

Abstract

The study aims to determine the effect of fermented patin fish waste (FPFW) by microbes Lactobacillus paracasei, Bacillus subtilis, and Saccharomyces cerevisiae (LBS) in rations on the digestibility of dry matter and crude protein, as well as obtain the level of use that produces the best digestibility of dry matter and protein in local chickens. The study used SNC(SNC) aged 14 weeks, as many as 24 tails, kept for 14 days. The experimental design was randomized, with six treatments and four repeats. Ration treatment is R0 (Lower control ration, protein 15% and EM 2750 kcal/kg, without the use of FPFW); R1 (R0 contains 5% FPFW ); R2 (R0 contains 10% FPFW); R3 (R0 contains 15% FPFW); R4 (R0 contains 20% FPFW); and RS (Upper control ration, protein 18% and EM 2750 kcal/kg, without use of FPFW). The results showed that the use of FPFW by LBS microbes had a significant effect (P<0.05) on the digestibility of dry matter and ration protein. Using 10% FPFW in the ration formula provides the best digestibility value of dry matter and crude protein of the ration on SNC.
