Toxicity of Jatropha curcas in sheep and goats

Abstract

The sequential development of the clinical signs and lesions in the organs of desert sheep and Nubian goats dosed with Jatropha curcas seeds at 0.05, 0.5 and 1 g/kg/day was studied. Diarrhoea, reduced water consumption, dehydration, sunken eyes, inappetence and loss in condition were the important signs of J curcas poisoning in sheep and goats. The main pathological changes were haemorrhage in the rumen, reticulum, lungs, kidneys and heart, catarrhal and/or haemorrhagic enteritis, hepatic fatty change, pulmonary congestion and oedema and straw-coloured fluid in serous cavities. An increase in the concentrations of AST, ammonia, potassium and sodium and a decrease in total protein and calcium were detected in the serum. Haematological changes were haemoconcentration and leucocytosis.
