Abstract

This study was focused on the variation of copper (Cu), zinc (Zn), manganese (Mn), selenium (Se), iron (Fe), iodine (I) and cobalt in tissues of slaughtered camels, she-camels and their newborn in five regions in Saudi Arabia during summer season. Whole blood, meat, liver, tumen fluid and blood tissues were collected from the slaughter house from each region. Moreover, blood samples from she-camels and their calves were collected from the same region at the same time. Samples were analyzed for trace minerals concentrations using ICP-MS. A significant variation for all trace minerals were reported between regions. A significantly higher concentration of all trace mineral in the were reported for liver samples that collected from camels slaughtered in southern part of Saudi Arabia, except Se and I, compared with other regions. Regarding the meat samples, a significant variation was also reported between all regions, except the iodine levels. Moreover, a significant correlation coefficient were found between most of the minerals especially meat with whole blood, rumen fluid and rumen tissues. On the other hand, A significant variations were reported for all trace minerals in blood serum of she-camels between different regions, except for the iodine. The same trend was also noticed for the calves, but the exception for the cobalt not the iodine. In conclusion, regions reported a variation between most trace minerals in term of the camel’s tissues from the slaughterhouse or she-camels and their newborns blood serum during the summer season.
