Milk ureas.

To resserect this thread....... @farmer on a bike I seem to remember you hold your milk ureas/diet protein fairly low. Is this the case and how low are we talking?

with our autumn calvers we try to stay between 200 & 300 mg/l (units can vary depending on how they are reported). In my view over 300 tends to hurt fertility and below 200 hurts yield. However if you cows were in poor condition and you wanted them to put on condition you may want to aim below 200.

Our urea is usually 0.030 to 0.035. Can go down to 0.021 in mid summer at grass. But generally high. Protein in silage is quite high this year. Fresh cows are on 6kg of 16% high energy type cake. Cow dung is usually quite loose. But fertility is generally good. A lot of the autumn calvers have been bulling recently. And I start serving 12th November. 1.355 was my latest bf ÷ protein. What range should this be?
 
Never look at mine , but seems to be just over 400 (1.2 ms/cow or 10% soilds) any other spring calver this high?

I've not had any that high recently. The last few have been between 120 and 250. Doing 9.5 litres @ 7 and 4.6 so about 1.1 solids.

Im still only on a 16% cake + grass + fodder beet and a bit of grass silage. Cows are finally starting to put on a bit of condition after looking a bit thin all summer.

In my view you cant really alter a spring calver much if most of the diet is grass. We have tried to go with 14% protein cake, but more recently we have used wheat gluten because it is cheap and we are only feeding 1.5kg to encourage them in the parlour so it has little impact.
