【 摘 要 】

The viability of gastrointestinal nematode eggs after aerobicfermentation was evaluated in two experiments. In the first, feces of sheep containing Haemonchus contorts eggs were submitted to aerobic fermentation by mechanical air pumping in a 300m3-capacity tank. In the second, bovine feces positive for eggs of the most common gastrointestinal nematodes were kept in a bovine fecal deposit in the field. Fecal samples from the two experiments were cultivated for the extraction of infective larvae. Both processes reduced the number of viable eggs. Reduction in the number of viable eggs were higher than 99% in both cases after 14 days of exposure.
