隐孢子虫感染检测到203（40.6%）的500安大略乳牛7日龄至21日龄，在方便的样品的51个农场小牛腹泻的历史。农场内的患病率范围为0%至70%，脱落和脱落强度与腹泻显著相关。这种寄生虫似乎在安大略奶牛中很常见，是该省奶牛腹泻的重要原因。
Cryptosporidium parvum infection was detected in 203 (40.6%) of 500 Ontario dairy calves aged 7 to 21 d, on a convenience sample of 51 farms with a history of calf diarrhea. Within-farm prevalence ranged from 0% to 70%, and both shedding and intensity of shedding were significantly associated with diarrhea. This parasite appears to be common in Ontario dairy calves and important as a cause of dairy calf scours in the province.
