Abstract :

Sample of each legume was ground to pass 3 mm sieve, put it in nylon bags (pores size 60 m2) and incubated in the rumen of 3 fistulated rumen fat-tailed sheeps fed on urea ammoniated rice straw ad libitum plus 20 g per kg 0,75 Susu Pap concentrates (CP 18.31%). Periods of incubation were 0, 4, 8, 12, 16, 24 and 48 hours. The dry matter (DM), organic matter (OM) and CP degradation values of each legume were subjected to nonlinear regression analysis according to the model : p = a + b ( 1-ect) for t  0 (Orskov and Mc Donald, 1979; Mc Donald, 1981). The design applied was Randomized Block Design. The data were statistically evaluated by analyses of variances and the significances between means were tested by using Least Significance Test. The results showed there were very significant different (p < 0.01) of DM, OM and CP degradation values among the legumes. The dry matter (DM), OM and CP degradation rates of calliandra were the lowest, i.e.1.40%/h, 1.76%/h and 2.09%/h respectively. The lowest degradation rate probably was due to its tannin content which was the highest among the other legumes. It is suggested to use erythrine, glyricidia, leucaena and sesbania for supplemention of low quality roughage feeds.
