[Parasite egg development during methane fermentation].
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.
