Cao GR, Alsalami MT., Terminalia oblongata toxicity in sheep, Onl J Vet Res 27 (5): 244-250, 2023. We report pathophysiology of chronic Terminalia oblongata (yellow-wood) intoxication in sheep. Leaf was dried, milled and drenched intraruminally to 7 sheep at various doses over several weeks. Chronic administration reduced rumen movements, induced inappetence or anorexia, body weight loss, reduced water intake and urine output. A normocytic, normochronic anaemia was found with blood gas and acid-base metabolic acidosis. For effect on reduced renal function, renal mass was reduced 50% but none showed decrease in renal concentrating ability. We deduce that sheep, not exposed to yellow-wood leaf, may have natural resistance and continued exposure may induce tolerance to the toxin. 

KEY WORDS: Terminalia, yellow-wood, tannins, sheep, intoxication.
