Also, ensiling the forage has been shown to reduce the nitrate levels by half at the time of completion of the fermentation process. Excessive nitrates typically accumulate at the base of the plant therefore, chopping or mowing the forage much higher than usual will help to reduce the amount of nitrate harvested. Delaying harvest until stress conditions have passed will help to lower nitrate levels within the crop. Departments of Animal Science and Plant Science, Penn State University.įor forages with known high levels of nitrates, there are a few management practices that will help to prevent toxicity. Penn State Extension Fact Sheet.ġTaken from: From Harvest to Feed: Understanding Silage Management, by C.M. ![]() Prevention and Control of Nitrate Toxicity in Cattle. Dilute to 900 ppm NO 3-N in total ration dry matter. Feed in a balanced ration with concentrate included. Nitrate Nitrogen (NO 3-N) (ppm dry matter basis) The only way to determine in excessive nitrate levels are present in forages is with a nitrate analysis.Ĭhart shows varying levels of nitrates and the toxicity potential to cattle. Nitrate Poisoningĭuring times of water stress or drought, or as a result of excessive nitrogen fertilization, nitrates and nitrites accumulate in the lower portion of the forage at a rate that is greater than what is normally present in the forage and can be toxic if consumed excessively by ruminant livestock. In most cases, more than one grazing or harvest can be obtained from these warm-season annuals if nitrogen fertilizer is applied following harvest or grazing to stimulate regrowth, allowing the forage to grow well into the cooler days of fall. Warm-season annuals are a widely-used, excellent way to provide forage for livestock in the summer months when cool-season perennials slow their growth – or during the "summer slump".
