Six out of 15 Nubian goats kids were given single oral doses of metolachlor (Dual 720 EC) at 2,000 or 500 mg/kg liveweight and died within 1 h of the dosing. Other 6 goats were given daily oral doses at 200 or 25 mg/kg and died or were slaughtered between days 8 and 25. In goats receiving single doses, the signs of poisoning were convulsive episodes, incoordination of movement, tremors, severe muscular spasms, stiffness, profuse salivation, respiratory distress, abnormal posture and recumbency. In goats receiving metolachlor at daily doses, the signs were similar, but developed slowly. Increases in the activities of serum AST and GGT and in the concentration of urea, and decreases in total protein concentration were correlated with clinical changes and lesions.

Twelve Nubian goats were given single or repeated oral dosages of mercuric chloride at 10, 20 and 40 mg/kg and died or were killed in extremis at various times after dosing (18 hours-18 days). The main signs of poisoning were anorexia, frothing at the mouth, respiratory distress, epistaxis, bloat, diarrhoea, abnormal posture and recumbency. An increase in the activity of GOT and in the concentrations of urea and inorganic phosphate and a decrease in total protein and calcium concentrations in the serum were detected. The main lesions were dilatation and necrosis of the proximal convoluted tubules, shrinkage and disappearance of the glomerular tufts, varying amounts of acidophilic homogenous material in the lumens of the affected tubules of the kidney, enteritis, hepatocellular degeneration and/or necrosis and pulmonary congestion, haemorrhage, oedema and emphysema. The changes in the red blood cells indicated anaemia.
