According to the plant owner, they reccomend a 2% intake per day, but I have always fed them no more than 1.5 body weight and free choice grass hay -- no other feed other than salt and mineral. They get to about 800 pounds or so pretty fast that way, but are not fat.
If you go past the 2% per day body weight in feed and still add other stuff to it, they will EXPLODE -- hehehe
You are using the best there is, get rid of the beet pulp for now, and make the total intake no more than 3% body weight including hay -- no alfalfa partner! Weight them often, like every two weeks -- both of thier mothers were fed the same ration as you have now, and they are tremendous cows.
Got a weight on them lately -- kind of curious.
Don't add any more calories than the ration already has, especially any higher protien, and keep your fat level down there where it is in the bag -- you will love the condition when they level out!
Keep up the good work down there in windy city!!!
