Avoid feeding high nitrate feeds to sick, hungry, pregnant or lactating animals. These animals have a lower tolerance level to the nitrate then compared to healthy cattle. Make sure all animals have access to plenty of clean drinking water as this will help dilute the nitrate in . Producers should dilute oat hay with low-nitrate feeds to avoid health issues if tests show the oat hay has 1, to 3, parts per million (ppm) of nitrate nitrogen. For pregnant cows and heifers, nitrate levels below 1, ppm are considered safe. Feed with nitrate levels less than 1, ppm are considered safe for other classes of : NDSU Extension.
But always test these feeds for nitrates in a lab to determine how to feed them safely. Remember, there are many ways to feed high nitrate hay safely. Diluting with grain or low nitrate forages is most common. Frequent, small meals that slowly increase the amount of nitrate fed helps cattle adapt to high nitrate . Deaths have been reported when the nitrate content in the overall diet was as little as per cent nitrate NO 3; however, rations containing substantially more than per cent nitrate NO 3 have been fed without harm. Researchers in Missouri fed steers rations containing to per cent nitrate NO 3 from sudangrass hay. The steers slowly adapted to the high nitrate feed and.
Nitrate (NO3) is not especially toxic, however in ruminants and herbivores, the bacteria in the digestive tract convert nitrate (NO3) to nitrite (NO2), which is readily absorbed and 10 times more toxic than nitrate. Nitrate poisoning can be a concern due to runoff . Regardless of the nitrate level, a good management practice is to fill cattle up with hay before turn-out. Use lower risk cattle, if possible. The group with the greatest risk of negative consequences due to feeding on high-nitrate forages is pregnant cows, as abortion can result.

Nitrate Poisoning and Feeding Nitrate Feeds to Livestock While nitrates (N0 3) are not very toxic to animals, nitrites (N0 2) are toxic.
In ruminant animals such as cattle, sheep, and goats, nitrate is converted to nitrite by bacteria in the rumen. This nitrite is then changed to ammonia. Excess ammonia is absorbed by the blood and passed in. nitrate in the feed, how fast the feed that contains nitrate is consumed, how fast the nitrate in the feed is released in the rumen, the energy content of the diet and whether the animals (i.e., rumen microbes) are adapted to nitrates.

The maximum amount of a nitrate compound (either calcium nitrate oR ammonium nitrate) that should be fed is shown below for cattle of different weights and fed.
The risk of toxicity depends upon the amount of nitrate in the feed, how fast the feed that contains nitrate is consumed, how fast the nitrate in the feed is released in the rumen, the energy content of the diet and whether the animals (i.e., rumen microbes) are adapted to nitrates.

Categories Beef Cattle Tags beef cattle, nitrate toxicity, nitrates, nutrition. Animals can die within a few hours of initial ingestion of a high nitrate feed. If cattle are fed once a day, maximum methemoglobin levels occur approximately eight hours after feeding.
When cattle are fed twice daily, maximum levels occur four to five hours after feeding. The once a day feeding program results in higher total methemoglobin Author: Barry Yaremcio.
Nitrate and nitrite poisoning in livestock. 3 | NSW Department of Primary Industries, May dampened by rain or snow some time before feeding out. Hays made from nitrate-rich materials contain almost as much nitrate as when first made, unless some is converted to nitrite by heating or mould.
Silage contains less nitrate than its parent. Testing nitrate levels in forages before feeding cattle can prove beneficial. by Heather Smith Thomas N itrates are compounds created by combinations of nitrogen and oxygen and are necessary for plant growth.
Almost all plants contain detectable amounts of nitrates when plant samples are tested for nitrate levels, but some typesFile Size: KB. Theensiling process reduces the nitrate level 40 to 60percent. If high levels of nitrate have accumulatedin plants, raisethe cutter bar and leave more stem, the portionof the plant with the highest concentrationof nitrate,in the field.
Have suspected forage tested before feeding to cattle. Dilute toxic forage by mixing it with nontoxic. Cut the feed high to avoid the nitrates concentrated in the stem. Avoid feeding greenchops for a few days following a rain because of the high nitrate levels. When pasturing high nitrate feeds, control initial intake by filling the cows with dry feed first.
Cattle should be limited to a small area with an electric fence to minimize Size: KB. Nitrogen (N) is an essential element for plant growth and thus a necessary part of global food systems. But when nitrogen concentrations are excessive or out of place, problems principle sources of nitrogen in our environment — plants, water and air — are interrelated (Figure 1).
Even though farmers may make proper fertility and crop management decisions, they cannot. • Allow for frequent intake of small amounts of high-nitrate feed because that helps adjust livestock to high-nitrate feeds and increases the total amount of nitrate that livestock can consume daily without adverse effects.
• Allow cattle time to adapt to increased nitrate in the diet. If nitrate levels are not excessively high (9, parts per. Feeding a high grain diet alongside high nitrate forage has a protective effect because carbohydrates enhance the conversion process from nitrate to microbial protein The animal can become conditioned to eat larger amounts of feed with a high nitrate content if the increase is gradual.
When a cattle’s diet is made up primarily of feeds containing excessive levels of nitrates, the poisoning process can occur rapidly, and the prognosis is poor. “The nitrates bind with hemoglobin in the blood, and the cattle can’t get oxygen,” says Bailey. Nitrate toxicity can be a serious problem in cattle and other ruminants.
They are more prone to toxicity because the microbes in the rumen convert nitrate (NO 3) to a more toxic nitrite (NO 2) r, since horses are hindgut fermenters and do not have the extensive ability to ferment forages like cattle do, the risk is lower.
Keys to feeding a forage that contains nitrates Dilute the forage that has nitrates to a safe level. Adapt cattle slowly over several days to forage that contain the high nitrates.
Never allow cattle that are hungry access to forage that contain high nitrates. Yet, that’s exactly what can happen when hay containing a high concentration of nitrates is fed incorrectly.
Eventually, most cattle producers who feed hay will have hay with high nitrates, especially when using millet, sorghum, oat or other cereal-based hays. But livestock losses do not need to occur if the hay is properly managed and fed.

Cattle can metabolize a certain level of nitrates, but if the diet contains more than approximately % nitrate (NO 3) on a DM basis subclinical toxicity can occur causing reductions in weight gain, decreased feed intake and milk production, and an increased risk of infections.Cattle losses to nitrate toxicity usually occur in hungry cattle that have not had time for some adjustment to feeds with potentially toxic levels of nitrates.
For example, cattle that go without feed for a day or longer during snow storms often rapidly eat a large amount when they finally gain access to feed.Utilizing High Nitrate Feeds Safely. Avoid feeding high nitrate feeds to sick, hungry, pregnant or lactating animals.
These animals have a lower tolerance level to the nitrate then compared to healthy cattle. Make sure all animals have access to plenty of clean drinking water as this will help dilute the nitrate in the animal’s body.
