This study aimed to determine the use of L. plantarum starter on a complete ration silage made from water hyacinth on protein digestibility and nitrogen retention. This study use fifteen rams (12 month old with anaverage body weight of 19 ± 3.98 kg). The sheeps were randomly devided into 3 treatment and 5 replications. T1 = elephant grass and concentrate, T2 = complete feed silage contain water hyacinth without addition of L. plantarum starter. and T3 = complete feed silage contain water hyacinth addition with L. plantarum starter. Feed structured treatment isoenergy and isoprotein (PK 13 % and 65% TDN). The result showed that the nitrogen retention, protein consumption, and protein digestibility was not significantly different among treatments. Protein consumption of treatment T1, T2 and T3 was 87,97, 108,00, 94,17 g/day, protein digestibility 77,29, 75,00, 77,07g/day and nitrogen retention was 8,82;10,47; and 8,29 g. and In conclusion, Complete feed silage water hyacinth can replace the fattening rations in sheeps.Key word : silage, L. plantarum, nitrogen retention, digestibility protein, sheep.
