Abstract

Three experiments were conducted to measure the preference, voluntary feed intake (VFI), and digestibility of forest type (FT) sheep fed untreated rice straw (RS) and supplemented with either sole or combined fodder tree leaves [Leucaena (L), Samanea (S) or Gliricidia (G) and their equal combinations]. The preference index (PI) was determined by consumption difference of the three fodder tree leaves (FTL), using 12 FT sheep (6 rams and 6 ewes of average weight 17.0 ± 1 kg). The sheep were offered the FTL in a cafeteria-style, and the consumption within the first 1 h was used to rank them. The sheep showed marked preference (P Samanea > Gliricidia. For the VFI study, a total of 24 FT sheep (16 rams and 8 ewes) of average weight 17.0 ± 1.0 kg were randomly assigned to 1 of 8 dietary treatments in a completely randomized design. The treatments were T1 (100% urea-ammoniated straw), T2 (RS + 100% L), T3 (RS + 100% S), T4 (RS + 100% G), T5 (RS + 50% L: 50% S), T6 (RS + 50% L: 50% G), T7 (RS + 50% G: 50% S), T8 (RS + 33% L: 33% G: 33% S). There were significant differences in the total and straw DM intakes. Total DM intake ranged from (523 to 694 g/d) whilst straw DM intake ranged from (430 to 692 g/d). The highest (P
