| dc.description | 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 28ºC and external temperature, from 26ºC to 33ºC. All the effluent samples showed a constant pH of 7. The samples of the effluent were weekly collected, in a total of 10, and submitted to techniques to detect the presence and viability of the helminth eggs. It was detected a 35-day egg viability. The infective larvae of Haemonchus, Cooperia and Oesophagostomum genus were found until the 14th day of observation and the infective larvae of Trichostrongylus and Ostertagia genus, until the 35th day. Therefore, liquefied cattle manure containing Strongyloidea eggs must remain under anaerobic conditions for at least 35 days before its safe return to the environment | |
