Abstract:
A study was conducted on Incidence of Haemoprotozoan diseases and Haematological alteration in crossbred cattle of Mehsana district, Gujarat from April, 2017 to March, 2019. A total 2885 (6 talukas) suspected blood samples examined at BAIF-Disease Surveillance. Laboratory, Vihar for the presence of haemoprotozoan infection by the Giemsa staining method. Total 742 samples found positive for protozoan infection. Incidence of haemoprotozoan infection was found highest for Theileria spp. (52.70 percent), followed by Anaplasma spp. (41.37 percent), mixed Theileria and Anaplasma spp. (3.10 percent) and Babesia spp. (2.83 percent). Incidence of haemoprotozoan infection was higher in winter season (30.29%), followed by monsoon (28.10%) and less in summer (19.96%). Lactation wise higher incidence of haemoprotozoan infection for 0-2 lactations group, 3-6 lactations and low in above 6^thlactations were 27.56%, 24.77% and 13.70% respectively. Mehasana taluka (38.71%) had higher incidence of haemoprotozoan infection. Theileria spp., Anaplasma spp., and mixed (Theileria spp. and Anaplasma spp.) infected cases shows comparatively decreasing the haemoglobin (Hb), pack cell volume (PCV), and total erythrocyte count (TEC) where as total leukocyte count (TLC) and differential leukocyte count was in the normal range (DLC). Babesia spp. infected cases showed comparatively decreasing the haemoglobin (Hb), pack cell volume (PCV), and total erythrocyte count (TEC) where as total leukocyte count (TLC) and differential leukocyte count in that the neutrophil cells range increased and the lymphocytes count is decreased.
