Abstract
Extract
Phenothiazine (thiodiphenylamine) has been regarded as comparatively non-toxic for sheep although abortion in ewes dosed late in pregnancy has been recorded by Hungerford and Howe Citation(1944). Whitlock et al. Citation(1945) described a severe mortality in lambs within one to two weeks, of phenothiazine therapy. Post-mortem examination revealed anaemia, fatty degeneration of the liver and anasarca.
