We start on the topdress at least 45 days out. We start out witha small amount per day of 2 lbs/hd and then each week we up it 1 lb and take out 1 lb. of stopper. We feed the high glo if the cattle are a little green and the orig. glo if they are finished. You will see good results with the 2 lbs per day but you will love it if you build them up to 7 lbs/hd/day the last 2 weeks prior to show.
