Abstract: Cryptosporidium spp. is a causative agent of cryptosporidiosis in newborn calves, often resulting in signs such as diarrhea, dehydration, and in severe cases, mortality. Cryptosporidium parvum, a predominant species, is known to affect calves. This study was aimed to document the prevalence of cryptosporidiosis in newborn calves. Fecal and blood samples were collected from neonatal calves and adult animals, with modified acid-fast staining used to detect Cryptosporidium oocysts in fecal samples. Hematological parameters were analyzed in blood samples, and results were compared to those of healthy control animals. The study revealed a higher occurrence of cryptosporidiosis in diarrheic male calves, highlighting their increased vulnerability. Additionally, prevalence was more common in younger animals, particularly those aged 0-6 months. Notably, the winter season exhibited the highest incidence of cryptosporidiosis. Hematological analysis indicated significant reductions in red blood cell parameters and a concurrent increase in white blood cell count among affected animals.
