الملخص EN

This study was conducted in animal farm belonging to Animal Resource Department-Agriculture College-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 concentration of blood glucose, total protein, urea nitrogen and triglycerides.

Lambs were randomly allocated into 6 equal groups with 4 lambs per each.

The last week of the study was designated to withdraw blood samples via jugular vein of all lambs at 3 intervals, before, 3 and 6 hours post feeding.

Results revealed that blood urea nitrogen was significantly affected (P<0.01) by treatment with higher level of urea, values were 41.67, 40.88 and 48.39 mg/100ml for levels 0, 1 and 2% of urea respectively.

Other studied blood parameters were not affected by ensiling and level of urea.

However, interaction between them significantly (P<0.05) affected blood total protein and urea nitrogen concentrations.

Higher (P<0.01) concentration of glucose was detected in blood samples withdrawn before feeding (79.86) as compared with those withdrawn at 3 and 6 hours post feeding (71.92 and 69.61 mg/100 ml respectively).

Whereas, higher (P<0.01) total protein and urea nitrogen concentrations were detected in blood samples withdrawn at 3 hours post feeding, values were 10.54 g/100 ml and 51.98 mg/100 ml respectively.

Higher (P<0.01) concentration of triglycerides was detected in samples withdrawn at 6 hours post feeding.
