Nitrates are less of a problem if pasture forages are not actively growing. Frequent intake of small amounts of a high-nitrate feen increases the total amount of nitrate that can be consumed daily without toxic effects. More of a high-nitrate forage can be fed witout harmful effects by feeding it in limited amounts several times daily rather thatn feeding large amounts once or twice daily. When nitrate is fed continuously, aminlas become adapted to higher nitrate concentrations and may be able to use a portion of dietary nitrate as nonprotein nitrogen. Do not use damp feed for livestock.
Dampness tends to heighten toxicity.
The probable explanation is that some of the nitrate is converted by bacterial denitrification to nitrite before animal consumption. Herd health is an important consideration. Healthy animals are less affected than animals in poor health. Parasitism or other conditions causing anemia will increase susceptibility. Nitrate toxicity does not appear to be altered and is not enhanced by simultaneous feeding or urea.
