Extract

West Java sheep are permanently housed and offered manually-harvested grass at 50-60 g dry matter [DM] per kg live weight [M] daily [d]. Flocks (ca. 5 head) are housed on slats, with excreta and feed refusals composted underneath.

In a previous experiment (Tanner et al 1993) with 18-month old Javanese Thin-Tailed rams, intake of cut-and-carried, indigenous grass increased as the amount offered was increased (25, 50 or 75 g DM offered/kg M.d; intakes were 22.1, 31.7 and 34.9 g DM/kg M.d respectively). Output of compost also increased with increasing amount of grass offered. In another experiment (Tanner et al 1994) supplementing grass offered at 30 g DM/kg M.d with rice bran fed at 30 g/kg M0.75.d achieved the same intake of digestible organic matter as unsupplemented grass offered at 60 g DM/kg M.d and reduced feeding costs by 15%. However, output of compost was reduced by 41% by rice bran supplementation, resulting in an unacceptable reduction in compost monetary-value.
