The hemostatic mechanism is crucial to stop bleeding while ensuring that tissues receive enough blood flow. This investigation examined selected haematological and coagulation parameters in different degrees of anemic Theileriosis infected cattle and study correlation between RBCs and platelet indices. Haematological analysis indicated substantial declines (p < 0.01) in total RBCs counts, PCV% and (Hb) in different degrees of anemic Theileriosis infected cattle compared with control group. In severe anemic group, MCV showed a substantial rise (p < 0.01) compared with moderate anemic group and (p < 0.05) compared with mild anemic and control groups; while MCH showed a substantial increase (p < 0.05) compared with mild and moderate anemic groups. In the coagulation profile, Platelets count (PLT) and PCT% showed insignificant difference (p > 0.05) among anemic groups compared with control group. MPV and PDW demonstrated substantial decreases (p < 0.01) in all anemic groups when compared with control group. In moderate anemic group, Prothrombin time (PT) exhibited a substantial prolongation (p < 0.01) compared to control group and (p < 0.05) compared to mild anemic group.  In severe anemic group, PT was significantly prolonged (p < 0.05) compared with control and mild anemic groups. Correlations between RBCs and platelet indices in mild, moderate and severe anemic Theileriosis infected cattle revealed significant correlations in all blood parameters. It could be concluded that different degrees of anemia caused by T. annulata infection in cattle are associated with marked changes in measured haematological and coagulation parameters.
