Metabolizable Energy Valueof-The Diets Containing Palm Kernel Cake (PKC) and Enzyme on The Kampongı Chicken at Nine Weeks Old

Abstract

Kampong chicken is a local chicken rhat domesticated in Indonesia. It was a domestication's result from jungle fowl that domesticated in Bangladesh, Pakistan, India, Srilangka and Semenanjung Melayu:Kampong chickens are potensial as poultry meat source in Indonesia. Feed cost is the highest component from operational cost in chicken's farm, so it must he "tried to use local feed ingredients that availahle and have good quality. One of them is palm kernel cake (pKq. Palm kernel cake is a waste product of palm oil processing that can he obtained by chemical process (ex" traction) or physical process (expeller). To improve PKC"" digestibility in karopong chicken's feed, an enzyme product thatcontain of protease,amylase, lypase and phytase· Can be used, There is no research to report the usage PKC as well as enzyme product in the karnpong chicken's diet. The experiment was conducted to study the effect of PKC and enzyme in the diet on the metabolizable energy value of nine weeks old karnpong chicken. Nine kampong chickens with the age'ofnine weeks which taken from ninetysix chickens that reared during nine weeks were used in this experiment. The "diets were: The diet without PKC (Rl), Rl + 0.1% enzyme (R2), the diet contain ofPKC (R3), R3 + 0.1% enzyme (R4). The pa=eter observed were energy consumption, energy excretion, apparent metabolizable energy (AME), nitrogen corrected apparent metabolizable energy (AMEn), true metabolizable energy (!"ME), nitrogen corrected true metabolizable energy (Th-fEn),nitrgen consumption, nitrogen excretion and nitrogen retention (NR). The experiment used Completely Randomize Design with four treatment and four replication and each replication contained orie kampong chicken. The data was analized by Analyses of Variance (ANOVA) and significant differences amonngtreatment.' were made by Duncan Range Test"(SAS Institute, 1997). The result showed that pkc as well as enzyme in the diet did not affect the"NR" AME, AMEn, TME and 'ThIEn. The conclusion from this experiment was the diet contained of 25% PKC without enzyme supplementation could he used as Kam.\?ong chickens diet.
