Ticks constitute the second vector group that transmit the major number of pathogens to humans and play a role primary for animals in the process of diseases transmission. Some ectoparasites that affect in cattle this infestation could result in skin damage, blood loss and severe anemia. It can induced the production of CBC counts (Total WBC, differential WBC, Total RBC, HCT, HGB, MCV, MCH, MCHC) and Fe, Mg tests. That study was done detect the hematology tests using mindray instrument and detect serum test (Fe, Mg, Ferritin) with kit from company equipped. They production of these tests with infection and comparison with the healthy animals (control). Significant difference in the (differential WBC, MCV, MCH, MCHC, Fe, Mg, Ferritin). and no significant difference in the (T WBC, RBC, HCT, HGB). The result showed significant differences in the MCV, MCH and MCHC (84.01 ± 10.35 , 89.58 ± 18.88) , (26.58 ± 1.50 , 29.73 ± 1.15) and (30.78 ± 1.25 , 35.86 ± 6.53), and The level in Fe, Mg and ferritin (5.60 ± 1.10 , 10.79 ± 4.01) , (0.54 ± 0.09 , 0.71 ± 0.02) and (8. 12 ± 2.35, 0.3 ± 0.48) in the patients groups were significant differences when compared with control groups (respectively). But result no showed significant differences in the White blood cells count (5.90 ± 0.12 , 7.76 ± 0.20), RBCs (5.21 ± 0.48 , 4.89 ± 0.77) , HCT (41.83 ± 10.78, 46.65 ± 11.56) and HGB (11.96 ± 3.43 , 13.81 ± 2.98) when compared between patients groups with control groups (respectively).
