| Abstract | ||||
| The present study was conducted on 218 Friesian calves, out of them 131 calves were suffering from diarrhea and 87 calves were apparently healthy. Faecal samples were collected from calves in different localities of Egypt (Middle Delta, West Delta and Upper Egypt). The parasitological examination (Macroscopic and Microscopic of the collected Faecal samples revealed that, the prevalence of Cryptosporidium and Giardia was 50.4% and 20.7%, of either diarrheic or apparently healthy calves respectively. The differences in the prevalence of Cryptosporidium and Giardia influenced by seasonal variations, the age of examined calves and geographical regions. The neonatal calves aged from birth till 2 weeks and 2 - 4 weeks old were highly susceptible to the parasitic infestation at the rate of 59.5% and 67.9%, respectively. The percent of recovery from cryptosporidiosis and giardiasis in diarrheic calves was 80 % when treated with Nitazoxanide only, while it reached to 100 % when the drug of treatment was accompanied with therapeutic supportive solutions (saline and ringers). | ||||
