The following precautions should be taken if a product contains urea or other NPN sources:
·         It is extremely important that products that contain a NPN source should be fed strictly according to directions.
·         A minimum of seven days adjustment period should be followed.
·         NPN sources are water soluble; therefore it is extremely important to protect farm feed and licks against rain. Animals drinking such a solution could easily be poisoned.
·         Do not feed NPN-containing farm feed indiscriminately with other NPN-containing farm feed. Consult an animal nutritionist.


NPN-poisoning can be treated with the addition of vinegar. Mix vinegar with an equal amount of water and dose ± 400ml per sheep and 1.5 – 2l per head of cattle.
