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.

The comparative effects of diazinon and malathion on Najdi sheep were described in sheep allotted as untreated controls, diazinon-treated at 25 mg/kg/d or 50 mg/kg/d, and malathion-treated at 25 mg/kg/d or 50 mg/kg/d. Although serum cholinesterase (ChE) activity was reduced, neither significant clinical signs nor severe pathological changes were produced in sheep dosed orally with 25 or 50 mg diazinon/kg/d for 21 d. Both oral dose levels of malathion were lethal to sheep between 1 and 6 d and caused, prior to death, hyperexcitability, tremors, clonic convulsions, salivation, nasal discharge, incoordination of movement, paresis of the limbs and recumbency. Lesions were widespread congestion and hemorrhage, patchy pulmonary cyanosis, gastroenteritis and hepatonephropathy. These changes were accompanied by increases in the activities of serum SDH and AST, in the concentrations of urea, triglyceride and cholesterol, and decreases in ChE activity and in RBC, PCV and Hb values.

Three-mo-old male Wistar rats were sprayed with 250, 500, 1000 and 2000 ppm amitraz 2 w apart or given single doses of 50, 100, or 250 mg/kg p.o, i.m. or i.p. No effects were observed in the amitraz-sprayed rats. Single doses of amitraz p.o, i.m. or i.p. was non-toxic at 50 mg/kg, toxic at 100 mg/kg and lethal at 250 mg/kg within 24 h of dosing. Survivors were killed 48 h post-dosing. Features of toxicity were depression, incoordination of movement, paresis of the limbs, hepatonephrotoxicity, muscular hemorrhage at site of injection and peritonitis following i.p. injection. These changes, accompanied by leucopenia, were correlated with alterations in serum AST and concentrations of serum constituents. Amitraz did not inhibit serum ChE activity.

The acute toxicity of dried Nerium oleander leaves to Najdi sheep is described in 12 sheep assigned as untreated controls, N. oleander-treated once at 1 and 0.25 g/kg body weight and N. oleander-treated daily at 0.06 g/kg body weight by drench. Single oral doses of 1 or 0.25 g of dried N. oleander leaves/kg body weight caused restlessness, chewing movements of the jaws, dyspnea, ruminal bloat, incoordination of movements, limb paresis, recumbency and death 4-24 hr after dosing. Lesions were widespread congestion or hemorrhage, pulmonary cyanosis and emphysema, hepatorenal fatty change and catarrhal abomasitis and enteritis. The daily oral doses of 0.06 g dried N. oleander leaves/kg body weight caused less severe signs and death occurred between days 3 and 14. In these animals, the main lesions were hepatonephropathy and gelatinization of the renal pelvis and mesentry and were accompanied by significant increases in serum AST and LDH activities, in bilirubin, cholesterol and urea concentrations and significant decreases in total protein and albumin levels, anemia and leucopenia.

Melia azedarach fruits were administered at single doses ranging from 5 to 30 g/kg bw to 10 calves. The animals dosed with 25 g/kg bw and 30 g/ kg bw died, as well as 1/2 cattle that received 15 g/kg bw. Clinical signs were depression, ruminal stasis, anorexia, diarrhea, incoordination, muscle tremors, difficulty to stand, sternal recumbence, hypothermia and dyspnea. Serum AST and CPK were increased. Signs appeared 4 to 24 h after dosing and the clinical manifestations continued for 20 to 72 h. Macroscopic findings included congestion of the intestine, focal or diffuseyellow discoloration of the liver, and brain congestion. LiQuid content was in rumen, reticulum and intestines. The liver had swollen and vacuolated hepatocytes, and necrotic hepatocytes were scattered throughout the parenchyma or concentrated in the periacinar zone. Degenerative and necrotic changes were in the epithelium of the forestomachs. There was also necrosis of lymphoid tissue. Skeletal muscles had hyaline degeneration and fiber necrosis.
