الملخص الإنجليزي

This study was performed to determine the nutritive value of some dominant rangeland shrubs in Karak region and the changes in the nutritional value of these shrubs through spring and summer seasons.

The dominant shrub species evaluated were Artemisia herba-alba, Atriplex halimus, Salsola vermiculata, Retama raetam, Acacia cyanophylla, Medicago arborea, Achillea falcata, Noaea mucronata, Anabasis articulata, Haloxylon persicum, Ononis natrix and Colutea istria.

Three replicates from each plant were sampled during spring and summer season.

After drying, samples were prepared for chemical analysis.

The results showed that there were significant differences (p ? 0.05) among species in their nutritive value.

Artemisia herba-alba had the highest CP content (18.27, 14.26 %) during spring and summer, respectively.

Atriplex halimus showed the highest content of Mg and Na with (0.65 and 3.55 %) respectively, during spring and highest CP (14.63 %), P (0.56 %), Mg (0.53 %) and Na (3.08 %) during summer.

Salsola vermiculata had the highest content of ash (18.94, 22.03 %) during spring and summer respectively.

Retama raetam showed the highest content of CF (48.34 %) and NDF (58.75%) during summer.

Noaea mucronata showed the highest content of Dry matter (DM) (51.71%), CF (36.75%), NDF (44.52 %) and ADF (33.18%) during spring.

Anabasis articulata had the highest content of Ca (1.72 %) and K (1.54%) during summer.

Ononis natrix had the highest content of crude fat (4.73%) and Ca (1.98%) during spring.

Colutea istria showed the highest content of P (0.77, 0.55 %) during spring and summer, respectively.

In conclusion the studied shrubs were varied in their nutrition value.

DM, Ash, CF, NDF and ADF tend to increase with maturity while CP, Crude Fat, and macrominerals (Ca, P, Mg, K, and Na) tend to decreased with maturity.

In general these dominant shrubs are more than feed requirements of small ruminants.

As recommendation we focus our attention on rangeland rehabilitation using the best quality shrub species like Artemisia herbaalba, Atriplex halimus and Salsola vermiculata which provide green forage with good nutrient source during dry seasons.
