  • Vinegar is an effective remedy against NPN poisoning. Mix with equal amount of water. Dose: Half a bottle per calf or large sheep or 2 to 4 bottles per head of cattle (1 bottle = 750 ml).
  • Protect this farm feed against rain. NPN is soluble and animals drinking such a solution could be poisoned.
  • Do not feed this farm feed indiscriminately with other NPN containing farm feeds.
  • Consult an animal scientist. This is a supplement and not a feed. Sufficient grazing and/or roughage must be available at all times.
  • Keep the lick troughs filled and prevent gluttonous eating by hungry animals. A constant daily intake can help to prevent poisoning.
  • Before feeding a NPN containing lick, feed an ordinary salt/phosphate lick for at least 7 days.
