Abstract

This study was conducted in animal farm belonging to Animal Production Department- College of Agriculture - AlQasim Green University using 24 Awassi male lambs at 4-6 months of age and mean initial weight of 20.59 kg, to investigate the effect of ensiling and level of urea (0, 1 and 2%) on ruminal fermentation characteristics. Results pointed out that pH was increased (P<0.01) due to ensiling, values were 6.91 vs. 6.71 for silage and reed respectively, yet it was not affected by level of urea. Higher (P<0.01) value of ruminal NH3-N was detected in samples withdrawn from lambs fed read treated with a high level of urea as compared with untreated reed silage (10.21 vs. 11.05 mg/100 ml for silage and reed respectively). Total volatile fattty Acid (TVFA) in the rumen was not affected by ensiling (5.67 vs. 5.65 mmol/100 ml) and level of urea treatment. Untreated silage and reed treated with 2% of urea recorded higher pH and NH3-N concentrations respectively. Higher pH and TVFA were recorded in samples withdrawn before feeding to be decreased at 3 hours post feeding.Then it was decreased after 6 hrs. NH3-N oncentrations while recorded higer level in samples withdrawn 3 hours post feeding, then it decreased at 6 hours post feeding, however, it was still higher than those recorded before feeding.
