title: Copper status of Najdi sheep in eastern Saudi Arabia under penned and grazing conditions.
abstract: 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.
