Abstract

The objective of the research was to examine unfermented solid cassava-waste (USCW) andfermented solid cassava-waste (FSCW) as the substitution of corn in broiler ration. Two hundred and tenbirds of one-week-male broiler chicken were divided into seven kinds of one-way treatment ofcompletely randomized design. Five replications were used for each treatment; there were six chickensin each replication. The substitution levels of corn in broiler ration by USCW and FSCW were 0%(control), 10, 20, and 30%. The result showed that corn substitution up to 20% using USCW and FSCWdid not affect the digestibility of feed (DF), digestibility of soluble protein (DSP) and crude protein(DCP), and digestibility of starch (DS). Substitution up to 30% using FSCW did not affect the DSP andDCP. However, substitution of USCW at the same level decreased DSP, DCP, DF, and DS. Cornsubstitution up to 20% using USCW and FSCW did not affect the feed intake (FI), body weight gain(BWG) and feed conversion ratio (FCR). Substitution up to 30% using FSCW did not affect the BWGand FCR. However, substitution of USCW at the same level decreased BWG and increased FCR. FSCWcan be used as a substitute for the corn up to 30% without affecting the performance and the values ofthe nutrient digestibility, meanwhile USCW is only able to substitute corn up to 20%.

Abstract

The objective of this research was to study the nutrient digestibility and the metabolizable energyvalue of the waste of saccharification process from cassava bagasse (WSPCB) on the laying hens.Twenty ISA-Brown laying hens at the age of 72 weeks were randomly distributed into three feedingtreatments which consisted of cassava bagase (CB), WSPCB of solid state fermentation method(WSPCB-SSF), and WSPCB of sub merged fermentation method (WSPCB-SmF). All of the hens werefasted for 24 hours and 15 of them were fed with CB, WSPCB-SSF and WSPCB-SmF (five hens foreach test-diet). The other five hens were still fasted. Then, all of the hens were fasted again and theirexcreta were collected during 48 hours. The nutrient digestibilities which were measured consisted ofthe Apparent and True Digestibility of Dry matter (ADDM and TDDM), Crude Fiber (ADCF andTDCF), Starch (ADS and TDS), and the Apparent and True Metabolizable Energy (AME and TME).The result of this research showed that the saccharification process generated the solid waste with thenutrient digestibility value (ADDM, TDDM, ADS, TDS, AME, and TME) which were significantlylower (P<0.05) than those of CB. The crude fiber digestibility value of the WSPCB has an opositephenomenon in which the ADCF and TDCF of WSPCB-SmF were greater than CB. In conclusion, thenutrient digestibility value, except for ADCF and TDCF, of the WSPCB on the laying hens were lowerin value than those CB.
