RETENSI NITROGEN DAN ENERGI METABOLIS RANSUM BROILER YANG MENGANDUNG TEPUNG SILASE KULIT PISANG KEPOK (Musa paradisiaca formatypica).

Abstract

NITROGEN RETENTION AND METABOLIC ENERGY BROILER RATIONS CONTAINING SILAGE KEPOK BANANA PEEL MEAL. Banana peel is a potential waste used as feed because their numbers are abundant and have the nutrients needed livestock. This study aims to determine the value of nitrogen retention (NR) and nitrogen corrected metabolizable energy value (AMEN) broiler ration containing silage kepok flour banana peel. This study involved 20 birds of broiler strains of Cobb at 6 weeks old. The completely randomized design was applied using four treatments and five replications for each treatment. The treatments were assigned into ration of 55 % corn without peel silage of kepok banana (R0), ration of 46.75% corn with 8.25% peel silage of kepok banana (R1), ration of 38.5% corn with 16.5% peel silage of kepok banana (R2), ration of 30.25% corn with 24.75% peel silage of kepok banana (R3). Variables measured were including nitrogen retention (NR) and nitrogen adjusted metabolic energy (AMEn). Results of analysis of variance showed that treatment significantly different (P <0.05) on nitrogen retention value and highly significant (P <0.01) against the value AMEn. Based on this study it can be concluded that the banana peel silage kepok flour (Musa paradisiaca formatypica)   can be used as one of alternative feed ingredients in the ration of broiler replace up to 30% corn 16.5% in the ration seen from Value Retention N (69.68%) while viewed from the AMEn (2924.92 kcal/kg) reimbursement to 15% or 8.25% in the ration.

Key word: Kepok banana peel silage, N retention, metabolizable energy, broilers.
