Abstract The causality of the serious hepatogen sheep ( Ovis aries ) photosensitization disease alveld is not explained.

Metabolites of saponins produced by N . ossifragum have long been suggested as the sole cause of the disease, here two additional hypotheses are discussed. Several findings have indicated that an unknown “cofactor” is required to explain causality. ...
