ABSTRACT
Parasitism is regarded as significant risk factor for the dynamic ability of small-ruminants and it sources enormous economic fatalities in most divisions of the globe as well as Pakistan. This study was designed with the objective to determine the hematological profile and prevalence of haemo-parasitic diseases in small ruminants and to correlate it with its health status. Total of 500 blood samples (Sheep, n=250, Goat, n=250) were collected from different areas of South Waziristan. Samples were processed meant for the incidence of haemo-parasites and diverse hematological limitations were anticipated. Prevalence of haemo-parasitic diseases was recorded as 14.4, 10.4 and 7.2% for anaplasmosis, theileriosis and babesiosis, respectively. Different risk factors were studied but statistical significant changes (p<0.05) were observed in prevalence of haemo-parasitic diseases with respect to season, breed, specie, age and sex. Hematological profile of diseased animals showed significant decrease (p<0.05) in TEC, Hb, PCV, MCH and MCV while no significant changes (p>0.05) were observed in MCHC and TLC. On basis of erythrocytic indices in sheep anemia can be classified as macrocytic normochromic while in goats anemia was recorded as macrocytic hypochromic. It can be concluded from the results that anaplasmosis was the most prevalent haemo-parasitic disease followed by Theileriosis and Babesiosis in the study area and along with general health status of the animal it also affect the hematological profile of animals.
