Abstract
This research was conducted in the Turbat (Kech) district of Balochistan. A total of 100 cattle were selected and divided into four groups based on tick infestation levels: the neutral group (no tick infestation, n=25), low infestation group (<40 ticks, n=25), mild infestation group (<80 ticks, n=25), and high infestation group (>100 ticks, n=25). A total of 321 tick specimens were collected, of which 258 (80.38%) were identified as Hyalomma anatolicum and 63 (19.62%) as Hyalomma dromedarii.
Hematological parameters showed significant differences between tick-infested and non-infested cattle. In all infested groups, blood parameters including total leukocyte count (TLC), total erythrocyte count (TEC), hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), packed cell volume (PCV), platelet count, lymphocytes, and neutrophils—were significantly decreased compared to the neutral group. Conversely, a significant increase in mean corpuscular hemoglobin (MCH) and eosinophil levels was observed in infested cattle relative to the neutral group.
