During the present study an investigation was made for the assessment of the availability of oocysts of Cryptosporidium spp. in 100 samples of raw milk of sheep and goats reared in various places (Baasheqa, Hamdania and Tilkaif) in Ninevah, Iraq. Results revealed that the incidence rate of Cryptosporidium spp. oocysts in raw ovine and caprine milk samples were 32%  and 46%, respectively. The type of rearing management has an effect on the incidence of oocysts in raw milk of these animals. Results showed that the contamination with Cryptosporidium oocysts in mixed (sheep and goats) rearing management of there animals was higher (p < 0.05) than separate rearing management.
