High milk urea

simx

My milk urea is gone high last week or so, cows well back too in litres, it's 44, what would ya reckon is the cause? Normal enough all year till now

What are they eating?

Mooooo

Sudden drop in litres or gradually? The urea being high would be too much p in the diet. Are they grazing ground recently fertilised? Could be the cause of high urea. Condition holding?

Sudden enough drop over 10 ish days, not fertilised that recently but got a nice shot last time round and could be still in it

If there was a burst of growth recently after a slow period of growth it could all come up now may explain the urea, are u getting much rain? Dm intake may be affected even if enough grass if grass is wet, are they hungry coming out of paddocks? All cows appetite would be at max now Much meal going in? Don't think the high urea would cause a drop in yield but I'm not sure.

A flush of n to the plant and energy diverted from making sugar to making n into protein?

N excretion could be costing around a kg of meal energy wise + less energy in grass

What could I do to counteract it? Feed straw?

Feed starch. Get some benefit from it. Barley, wheat or maize meal. You should get good bang for your buck milk wise.

Oaten straw has a neutralising effect on blood urea. Access at a head feed during milking at times of high nitrogen in grass might be no bad idea.

Did the milk urea come down? High milk urea can cause embryonic loss
