Effect of feeding lasalocid to pregnant ewes experimentally infected with Toxoplasma gondii.
Sixteen 50 day gestational ewes were fed lasalocid at the rate of 30 g t-1 and were orally inoculated with 100 infective Toxoplasma gondii oocysts 5 days after beginning feeding of lasalocid. Seventeen control ewes were similarly inoculated with T. gondii and were not fed lasalocid. The rate of abortion and neonatal mortality in both treated and untreated ewes was similar, indicating that feeding lasalocid was not effective in preventing T. gondii abortion in sheep.
