<![CDATA[This study aims to determine the efficient use of protein and energy of Black Soldier fly larvae at different age levels on chicken. This research was conducted at Jl. RK, Desa Namo Bitang, Kecamatan Pancur Batu Kabupaten Deli Serdang, North Sumatra. Animal Husbandary Study Program, Faculty of Agriculture, Universitas Sumatra Utara, Medan. The design of this study was a completely randomized design (CRD) with 4 treatments and 5 replications. The treatment consisted of P0, P1, P2, and P3 (larvae 14, 21, 28, and 35 days old). Observed variables were protein digestibility, nitrogen retention and apparent metabolizable energy.The results showed that the treatment had a significant effect (P<0,01) on protein digestibility, nitrogen retention and apparent metabolizable energy. Based on research result it can be concluded that maggot of Black soldier fly more efficient at the age between 24-25 days.]]>
