The Prophylactic Effect of Corn Supplementation on Experimental Nitrate Intoxication in Cattle¹

Oklahoma State University, Stillwater 74078-0353

Abstract

Sodium nitrate was administered through rumen cannulae to produce NO^–₃ intoxication in four cows (382 to 445 kg body wt) fed prairie grass hay and a protein-mineral supplement. The cows were fed 0, 1.6 or 3.2 kg of dry rolled corn daily for 10 d prior to sodium nitrate administration. Sodium nitrate administration was followed by a marked increase in intraruminal NO^–₂ and NH₃ and blood NO^–₂ and methemoglobin. Six of eight cows fed 0 and 1.6 kg of corn were given methylene blue to treat severe methemoglobinemia, while none of the cows fed 3.2 kg corn required such therapy. Feeding of 3.2 kg of corn protected against nitrate poisoning by reducing intraruminal nitrite and blood methemoglobin (P<.05)
