Evaluation of bovine perinatal nitrate accumulation in western Nebraska.
Nitrate-nitrite toxicosis causes numerous cattle deaths every year in western Nebraska. Its role in fetal abortions is complex and still speculative. This paper reports composite fetal nitrate diagnostic levels, fetal abattoir nitrate levels and observations of bovine perinates from cow-calf livestock units.
