Abstract
One acre of Ruzi pasture under rainfed condition was divided into 3 blocks each with 3 subplots of 3 cutting ages at 30 45 and 60 days. Yield was measured and samples were taken for chemical analysis. Organic matter digestibility and energy value of the grass were evaluated by in vitro gas production technique. Available nutrients ME and NEL per acre per 120 days were calculated. It was found that the concentration of DM NDF ADF and ADL increased with age while that of CP EE and ash decreased significantly. The fastest growth rate of ruzi grass was during 30 to 45 days of age. Nutrient concentration of the grass cut at 30 45 and 60 days of age were:- CP 12.1 9.3 and 6.4; NDF 58.3 67.4 and 71.3; ADF 28.9 33.3 and 37.4; OMD 61.5 55.7 and 54.3 ME 2.26 2.05 and 2.00 NEL 1.35 1.20 and 1.17 Mcal/kg DM respectively. Available nutrients per acre per 120 days of wet season were highest when grass was cut every 45 days with the exception of CP which was highest at the 30 days cut.
