Abstract
Fifteen Awassi lambs with average body weight 41.5kg were ditributed into 5 groups each of 3 lambs to study the effect of restricte of feeding of dry matter or drymatter and energy by 10and 20% of and – libtum feeding on national digestiblity, some rumen lupers parameters and blood charactaristics. Results indicated that restricted feeding of dry matter (T2 & T3) and dry matter and energy (T4 & T5) had a significant (p <0,01) improvement on dry matter digestibility (76.40 – 82.68%) and organic matter (78.86 – 84.50%) as compared with (T1) (71.45 & 72.95%) respectively. Also, it was noted a significant (p < 0,05) improvement in protein, ether extract acid detergent fiber and neutral daren't fiber. The different levels of restricted feeding had no significant effect on rumen liquor PH before and after feeding, but it was noted a significant (p<0.05) increase in PH values when the comparison was between before and after feeding within each level of restrict feeding. However , it was noted that restricted feeding had no significant effect on ammonia concentration in rumen liquor before and after feeding, while a significant (p<0.05) effect when the comparison was between ammonia concentration before and after feeding within each level of restricted feeding. The biochemical analysis of blood showed that restricted feeding had no significant effect on blood glucose, urea, total protein, albomin, gloubulin and the triglyceride.
