Story: Diseases of sheep, cattle and deer

Nitrate poisoning of cattle

Any new grass has the potential to cause nitrate poisoning, which can occur from half an hour to four hours after starting to graze. A nitrate concentration of more than 0.2% of dry matter can cause this problem. Farmers should avoid putting hungry cows on new pasture, and carefully ration the amount available. If they call a vet as soon as noticing a problem, it can be cured with an intravenous injection.
