The highest prevalence of Anaplasma spp. and Babesia spp. (25% and 10% respectively) was reported in the older cattle (> 3 years of age) and the prevalence of Anaplasma spp. and Babesia spp. was higher in female (20% and 10% respectively) than male (13.33% and 3.33% respectively). All crossbred cattle showed higher prevalence of Anaplasma spp. and Babesia spp. (23.33% and 10% respectively) than local cattle (10% and 3.33% respectively).
