An increase in fed protein while grazing corn stalks or late season forages will help increase forage digestion. The 30-13 tub is great for that. The high fat tubs have different levels of fat to be paired with the energy requirements and the body condition of your cows and different levels of protein to match up with your forages. Remember it is easier to build back body condition while it is still warm out then doing it in Jan/Feb. Kari and Katie are available to help you decide which one fits your operation.
