SOURCES OF UREA POISONING

• Urea and other organic and inorganic sources of nitrogen are added to ruminant rations as a source of non-protein nitrogen.

• It is also used as a fertilizer.
• Ruminants generally obtain excess urea in feeds or in urea molasses mixtures.
• Sometimes mixing may not be proper and sometimes animals which are not accustomed to ingesting urea may ingest too much of it.
• Ammonium salts are used as expectorants and in urolithiasis.
• Urea, biuret and ammonia serve as non protein nitrogenous agents.
