The siimnhemp (Crotalaria juncea) fodder harvested at flowering stage, was processed into hay and evaluated for nutritive value using for Nellore brown ram lambs (18.8 ±0.70 kg) in first experiment. The DM intake was 543 g/d. The DCP and TDN value of sunnhemp hay was 11.5 and 55.1%, respectively. In the second experiment, four isoraitrogenous complete rations (CR) were formulated by replacing groundnut haulms by sunnhemp hay at 0 (CR-1), 15 (CR-2), 30 (CR-3) and 45 (CR-4) parts (WAV) and evaluated in a 4x4 Latin Square design using 4 Nellore brown ram lambs (16.7±0.5 kg). Increasing the sunnhemp hay in the complete rations decreased the digestibilities of OM, CF and NFE linearly (P<0.01). All animals were in positive N, Ca and P balances. DCPand TDN of CR-1 to CR-4 were 8.24 and 68.30; 8.33 and 68.60; 8.34 and 64.98 and 8.55 and 64.08 per cent, respectively. It is concluded that sunnhemp hay can be safely incorporated upto 45% level in complete rations of sheep under intensive system of feeding.
