Studies were carried out on desert sheep and Nubian goats fed on Solanum dubium (Gubain), Jatropha curcas (Habb El meluk) Hibiscus trionum and mixture of the latter plants in fixed proportions. A number of liver and kidney function tests were carried out and the results were correlated with clinical and pathological changes. There was an increase in activity of glutamate oxaloacetate transaminase and in concentrations of creatinine and ammonia and decrease in levels of total protein, calcium and magnesium in serum of S. dubium poisoned animals. Anorexia, dyspnoea, depression, ataxia, bloat, loss of condition and recumbency were the main clinical signs of S. dubium poisoning in sheep and goats. Inappetence, reduced water consumption, profuse diarrhoea, dehydration and steadily deteriorating condition were important clinical signs of J. curcas intoxication in goats. The lesions consisted of haemorrhages in the rumen, reticulum, omasum, kidney, heart and spleen, catarrhal or haemorrhagic enteritis and abomasitis, congestion and oedema of the lungs and excessive fluid in serous cavities. There was a decrease in concentrations of total protein and calcium and an increase in the concentrations of potassium, sodium and ammonia and in the activity of GOT in the serum. Haematological changes were haemoconcentration and leucocytosis. Profound depression, diarrhoea, respiratory distress, inappetence, salivation abdominal pain, weakness of the hind limbs and recumbency were the prominent signs of H. trionum poisoning in goats. The main pathological changes were haemorrhages in the heart, kidney and lungs, catarrhal enteritis, hepatic fatty change and necrosis, serous atrophy of the cardiac fat and small amounts of straw coloured fluid in serous cavities. These changes were correlated with those in serum constituents and blood cells. A mixture of J. curcas and H. dubium caused more rapid death than either of the individual plants
