BACKGROUND: Cobalt is an essential nutrient for ruminants which is required for the synthesis of vitamin B12 by the ruminal microflora. Cobalt deficiency can lead to a deficiency of vitamin B12, which plays a major role in many metabolic reactions in the body. OBJECTIVES: This study was conducted to evaluate cobalt status in the serum and liver of cattle. METHODS: In different seasons, the blood serum and liver concentration of cobalt in slaughtered cattle in Urmia city were measured by atomic absorption in 151 and 196 cattle, respectively. RESULTS: The results of cobalt measurement indicated that in 12.6% of serum and 21.4% of liver samples the concentration of cobalt was less than normal range with the Mean ± SD value of 0.64 ± 0.25 µg/dl and 0.15 ± 0.04 µg/gDM, respectively. The seasonal variations of cobalt values were assessed in serum and liver samples and following results were obtained: spring (2.18 ± 1.64 µg/dl, 0.23 ± 0.13 µg/gDM), summer (3.42 ± 1.04 µg/dl, 0.42 ± 0.27 µg/gDM), autumn (3.45 ± 0.37 µg/dl, 0.47 ± 0.38 µg/gDM) and winter (2.75 ± 0.59 µg/dl, 0.35 ± 0.09 µg/gDM). CONCLUSIONS: According to the results of this study, it seems that there is a subclinical deficiency of cobalt in cattle of this region and it is recommended that preventive measures be considered to prevent the complications and disorders caused by its clinical deficiency.
