[The Effect of Usage Level of Fermented Palm Kernel Cake-Cassava Byproduct Mixture in Ration on Broiler Performance]

Abstract

This experiment was conducted to evaluate the effect of usage level of palm kernel cake (PKC)-cassava byproduct mixture fermented by Aspergillus niger in ration on broiler performance. Ninety six DOC of broiler were used in this experiment. The birds were reared in litter floor pen and was fed of 0 %, 10 %, 20 %, and 30% of the fermented PKC-cassava byproduct mixture of the total ration for 6 weeks. The broilers were fed ration and water drinking was available ad libitum. The experimental treatments were designed to a completely randomized design with 4 ration treatments and 4 replications, and each replication consisted of 6 chicken. The data were analyzed using ANOVA and continued by the Duncan’s multiple range test. The result showed that the level of fermented PKC-cassava byproduct mixture in broiler ration affected (P<0,06) feed consumption, body weight gain, and income over feed cost chick, but did not affect (P>0,06) feed conversion. The use of fermented PKC-cassava byproduct mixture until 30% in the ration was better treat-ment compared to the control. Keywords: palm kernel cake, cassava waste, fermentation, performance, broiler
