I have 40 cows and 1 bull that I have on average hay. I also keep 2 protein tubs out at all times. I am wanting to know what and how much to supplement them with as far as feed goes. I have been giving them 100 lbs of ground corn with some soy meal. This costs around $8.50 per day. What would be best in your opinions for me to do to keep them in shape. The bull gets around 5 lbs of this feed alone. I have 7 with calves. The others are being bred right now. Thanks
