Investigations were carried out on the development of the most frequently encountered parasitic diseases in farm animals raised under industrial conditions. The parasite eggs were obtained from great numbers of animals with fascioliasis, dicrocoeliasis, ascaridiasis, and paramphistomum infection, etc., and were mixed with fecal homogenate in a lagoon of a fermentor in the conditions of methane fermentation. It was found that the parasite eggs in such conditions retained their vitality in a state of anabiosis. After the fermentation procedure was over and the manure compost mass was spread in the field the parasite eggs could resume their biologic development and become infective. This made it necessary to compost the manure liquid and use it after subsidiary thermal treatment.
对在工业化条件下饲养的家畜中最常见的寄生虫病的发展情况进行了调查。从大量患有片形吸虫病、双腔吸虫病、蛔虫病和前后盘吸虫感染等疾病的动物身上获取寄生虫卵，并在沼气发酵条件下，将其与粪便匀浆混合在发酵罐的泻湖中。结果发现，在这种条件下，寄生虫卵以隐生状态保持其活力。发酵过程结束后，将粪肥堆肥施用于田间，寄生虫卵可恢复其生物学发育并具有感染力。因此，有必要对粪液进行堆肥处理，并在辅助热处理后使用。
