Viability of Bovine`s Strongyloidea eggs in a System of Anaerobic Biodigestion

Cattle Strongyloidea egg-viability was studied in closed system of anaerobic biodigestion. Two thirds of a biodigestor were filled with liquified manure from eight Hosltein cows, nacturally infected. For 10 consecutive weeks of observation, the biodigestor internal temperature varied from 24ºC to 28...
