Blood and ruminal fluid profiles in carbohydrate-foundered cattle.

摘要: The relationships of acetylhistamine and histamine to the clinical signs carbohydrate-induced acidosis were investigated in beef steers. Blood pH plasma L-lactic acid decreased serum sodium, potassium, ruminal fluid acid, histamine, blood increased carbohydrate-engorged steers as compared with changes while feeding on pasture (forage-fed steers). Twelve 14 hours after had become engorged, laminitis ("feedlot founder") observed three six These appeared 4 6 attained maximal concentration (2.9997 +/- 1.7054 microgram base/ml blood) 7.260 0.026 at 8 engorgement. value reached 0.1298 0.1095 engorgement (8 10 before appearance illness), but 32 (0.3300 0.028 blood).
