Pengaruh Serat Kasar Ransum Terhadap Pertumbuhan, Produksi, Dan Penyerapan “Volatile Fatty Acids” Pada Itik Tegal

Abstract

The objective of this research was to evaluate the effect of crude fiber on growth performance, production and absorption of VFA on Tegal duck. Material in this research was day old duck. This research was designed following completely randomized design of one-way pattern. Treatments were level of crude fiber at 5, 10 and 15% of ration dry matter. Data were analyzed with analysis of variance and when there was an effect of treatments, then it was continued by Duncan multiple range test. Result of this research showed that the treatments did not significantly effect diet consumption (P1 = 71,53, P2 = 69,54 and P3 = 66,19 g/day) and growth performance (P1 = 19,75, P2 = 19,07 and P3 = 18,83 g/day). Levels of crude fiber in duck rations did not significantly influence the VFA production (P1 = 1019,98, P2 = 1053,21 dan P3 = 1103,18 ?mol/l) and VFA absorption (P1 = 230,15 , P2 = 251,97 and P3 = 266,17 ?mol/l.). It can be concluded that the level of crude fiber up to 15% can be tolerated by Tegal duck without influencing the diet consumption and growth performance. Crude fiber 15% did not increase VFA production and absorption VFA. 1) Staf Pengajar Jurusan Nutrisi dan Makanan Ternak, Fapet, UNDIP 2) Mahasiswa Jurusan Nutrisi dan Makanan Ternak, Fapet, UNDI
