Fermentasi Bungkil Inti Sawit dan Tepung Daun Indigofera untuk Meningkatkan Nilai Protein dan Energi Metabolisme pada Ayam Kampung Unggul

Abstract

Palm kernel meal (PKM) and indigofera leaf meal have high protein content, but also high crude fiber content. The effort to reduce the crude fiber content in PKM and indigofera leaf meal is through the fermentation process using Aspergillus niger. This study aims to determine the effect on fermentation of PKM and Indigofera Leaf Meal using A.niger on KUB (Kampung Unggul Balitbangtan). Uses 23 KUB aged 16 weeks divided into five treatments with four replications. The treatment consists of different percentage dosis A.niger P0 (0%), P1 (0,5%), P2 (1%), P3 (1,5%), dan P4 (2%). The parameters observed are Retention nitrogen (RN), net protein utility (NPU), and energy metabolism (EM). Result is PKM and Indigofera Leaf Meal fermented with A.niger have a significant effect (p<0,05) on RN with an average ranging from 48,07%-75,19%, and have a significant effect (p<0,05) on EM with an average ranging from 2200,52-2853,82 Kkal/kg. However, it didn’t have a significant effect (P>0,05) on NPU. The conclution from the results of study is the best treatment was obtained at P4 with dose percentage of A.niger 2% because it can have the best RN, NPU and EM values compared to other treatments.
