There is soybean meal in beef concentrate. Can you feed urea?

Please understand the friend to say! [ts] woshixinshou added the following at 17:58 on 2009-12-17 17:58 [/ ts] what if not? For example, replace the soybean meal with something else! -it works! The amount of urea used in a day should not exceed 50 grams. -Urea is replenished because there is not enough protein.-I don't know, but I do.-not too much, because there are ureases in soybean meal.-before feeding. Also calculate the protein content of your feed, if the protein reaches 12%, do not feed it!
