In five large calf-houses and seven farms, 943 calves at the age from one to 198 days were examined coprologically; the feces of 224 animals (23.7%) contained coccidium oocysts of the genus Cryptosporidium. The cryptosporidium oocysts were counted in the Bürker chamber by means of the original method, and their mean number in 1 g of feces was the highest in the animals of the age from 11 to 20 days (3.0 +/- 2.4 million in the calves suffering from scours and 4.2 +/- 4.1 million in the calves without scours). Statistical comparison of the mean weights of heifers was performed at the time of their delivery to the calf-house and showed no statistically significant influence of cryptosporidia on the weight of animals.
在5个大型犊牛舍和7个农场，对943头年龄在1至198天的犊牛进行了粪便学检查；224头动物（23.7%）的粪便中含有隐孢子虫属的球虫卵囊。采用原始方法在 Bürker 计数室对隐孢子虫卵囊进行计数，1克粪便中卵囊的平均数量在11至20日龄的动物中最高（腹泻犊牛为3.0±240万个，无腹泻犊牛为4.2±410万个）。在小母牛进入犊牛舍时对其平均体重进行了统计比较，结果显示隐孢子虫对动物体重没有统计学上的显著影响。
