► Ensilation treatment of Taenia hydatigena eggs for 0, 7, 14, 21 and 28days. ► Infection of lambs with ensiled eggs. ► Slaughter after 49days and cysticerci recovered. ► Maximum reduction in viability of 99.9% attained at 18.59days of ensilation.
A Taenia hydatigena model was used to assess the effect 0, 7, 14, 21, and 28days of ensilation of minced potato on viability of tapeworm eggs. For infection of lambs, 2,000 T. hydatigena eggs were ensiled for 0, 7, 14, 21 and 28days in minced potato at 22°C and fed to recently weaned lambs (29.9±0.76kg). At slaughter, no cysticerci were recovered from lambs infected with eggs ensiled for 28days while a mean of 5.0±5.0 cysticerci (0.25% of the initial egg dose) were recovered from lambs infected with eggs ensiled for 21days. For lambs fed eggs ensiled for 0days (control), 359.3±55.6 cysticerci were recovered (18.0% of the initial egg dose). Regression analysis revealed that a 99.9% reduction in viability was attained after 18.59days of ensilation.
