The aim of present study was detection of parasites cause diarrhea in calves, their seasonal prevalence, and comparative studies on efficacy of chemical drugs (Ivermectin) and natural extracts (Artemisia) against those parasites. 208 fecal samples of diarrheic calves 80 suckling calves (41 cow calves + 39 buffalo calves) & 128 weaned calves (88 cow calves + 40 buffalo calves). The samples were taken From (February2014 to January 2015) from different localities in Munofyia Governorate. The results revealed that the incidence of parasitic diarrhea in suckling calves was 60.1% and 58.5% in cow and buffalo respectively. The study indicated that, the weaned diarrhetic cow calves were 68.2% more than that of buffalo 50%. The detected parasites were Toxocara vitulorum, Trichstrongylus spp., Eimeria spp. and Cryptosporidium spp. The seasonal variation of Toxocara vitulorum was 45.5% in winter, while the other seasonal variation were 27.3%, 18.2% and 9.09 % in autumn, spring and summer respectively. Trichstrongylus spp. was in spring 50 % and 30% in autumn. While it was in winter (20%) and 0% in summer. In case of Eimeria spp. it was 13.1 %, 41.3 %, 26 .9 % and 40% in winter, spring, summer and autumn respectively. The study, indicated the seasonal variation of Cryptosporidium spp. were 20 % , 30 % ,17.5% and 32% in Winter, Spring, Summer and Autumn, respectively. The results of treatment were, the reduction percentage of eggs per gram (EPG) of nematodes was 100% within first week for Ivermectin, while it was 75% within second week and was still for Artemisia.
