Urea is a very cheap form of protein for ruminants. It is a form of protein called non-protein nitrogen (NPN) because it is not like the proteins found in meat, soybeans meal, fish meal etc. But mricrobes in ruminants' belly can use it as protein and multiply. When they die, the animal will use them as a source of protein.
Urea can do wonders in terms of promoting growth or milk yield. But too much can lead to disastrous effect. For milking cows, give a maximum of 220g per cow per day. But 110 to 150g per cow per day is more common. Mix it in the concentrate feed to achieve 1 to 2% urea in the total grain ration or 2.8 to 5.6% crude protein from NPN in total grain ration.
Urea contains about 262 to 287% crude protein.
Don't feed urea together with raw soybeans hull because an enzyme in the hull will break down urea to ammonia, causing poor palatability (poor feed intake). Also, don't feed it to calves less than 3 months old.
