Hepatotoxicity of Two Progoitrin-Derived Nitriles in New Zealand White Rabbits.

Cattle occasionally develop brassica-associated liver disease (BALD) and photosensitisation when grazing turnip or swede ( spp.) forage crops. The liver toxin in these brassica varieties has yet to be discovered.

Investigating the cause of -associated liver disease (BALD) in cattle: Progoitrin-derived nitrile toxicosis in rats.

A large outbreak of liver toxicity in dairy cows that were consuming swede (rutabaga, ssp. ) crops in Southland and Otago, New Zealand in 2014 prompted the search for the toxin(s) responsible for brassica-associated liver disease (BALD). Analysis of swede plant material showed that the ultra-dominant glucosinolate was progoitrin.
