Thirty Ossimi lambs of 31 .4 kg average live body weight were divided
into 6 experimental groups of 5 animals each for feeding trial . In-addition, 18
Ossimi mature rams were used for a metabolism trial, 3 animals in each group. The plans of feeding were : G I) I 00% of concentrate was offered before berseem and water. G2) 50% of concentrates were offered then berseem and water then the rest of concentrate. G3) Experimental animals were fed berseem and water followed by 100% of concentrate. G4) I 00% of concentrate then water before berseem .G5) 50% of concentrates were offered then water before berseem and 50% of concentrate G6) water, berseem and I 00% of concentrate at morning.
There were no significant differences in DM intake due to feeding
sequences , G5 had the highest live body weight and the highest values of feed efficiency related to DIV"'I, CPI, TDNI, SVI, DCPI (0.188, 1.46, 0.257, 0.296 and 1.57 gm, respectively) than the other values for feed efficiency. Values of nutrient digestibilities, feeding values {TDN , SE and DCP) were the highest for G5. The nitrogen balances were positive for all experimental groups. Water
apparent balance relatively to metabolic body size (mllkg w"•" ) was higher for
G5 than Gl.
Rumen pH ,the highest value (p<0.05 ; 6.95 ) was recorded for G3 after
2 h post first feeding. Rumina!ammonia-N concentration, there were the high value for G2 at zero and 2 h post first feeding, while after 4 h G I was the highest value. Animals of G2 showed the highest value of rumina!TVFA' s (15.68 m.eq/IOOml) at 2h and 4h post first feeding. Animals ofG2 had the highest plasma total protein (9.04 gm/1OOml) after 2 h post feeding and G3 showed lower plasma urea value (32.45 mg/IOOml) than Gl (48.85 mg/IOOml).
