A sheep bioassay developed for the estimation of phomopsins-associated toxicity in feed samples infected with Phomopsis leptostromiformis is described. The procedure for scoring microscopic liver damage in the sheep bioassay was modified to enable assessment of the severity of lupinosis in sheep grazing toxic lupin stubbles for various periods. The microscopic changes assessed had a dynamic interrelationship with each other, and with other parameters including the daily intake of phomopsins and the period
