Can I feed Urea to newly weaned calves?
Young calves, under 450 pounds or 120 days of age cannot use urea as a protein source efficiently. If urea is to be added to a ration, calves larger than 450 pounds and older than 120 days, need to become accustomed to the urea in the ration over a 10 to 14 day adjustment period.
What does urea provide in a ration?
Urea provides “non-protein nitrogen” in a ration. This protein is not from plant sources, but is suitable for use with some restrictions. There is no energy, macro- or micro- nutrients or vitamins in urea.
