Copper status of Najdi sheep in eastern Saudi Arabia under penned and grazing conditions

  • K. E. Ali

Concentrations of serum copper were significantly lower in penned Najdi sheep (zero grazed) than in grazing sheep in eastern Saudi Arabia. Soil-plant-animal interrelationships studies suggest that this could be attributed to the low copper to molybdenum ratio in the forages (berseem and Rhodes grass) fed to the penned sheep as compared to pasture plants. This was in line with the status of these minerals in the soils.

Les concentrations sériques du Cu ont été significativement plus basses chez les moutons Nadji maintenus en enclos que chez ceux admis au pâturage. Des études sur la relation sol-plantes-animal donnent à penser que cette situation pourrait être due au faible taux cuivre-molybdène dans les fourrages (Berseem × Rhodes grass) par rapport à celui des plantes des pâturages qui se trouvaient être du même ordre que ceux des sols, pour la teneur en ces deux minêraux.


La concentratión de cobre sérico fue significativamente menor in ovejas Najdi estabuladas, que en ovejas en pastoreo. La relación suelo-planta-animal sugiere, que el fenómeno peude atribuirse, al bajo contenido de cobre en el alimento (berseem y pasto Rhodes) suministrado a los animales estabulados, en relación con el adquirido por los animales en pastoreo.
