How much grain can be fed during cold weather to meet the cow’s additional energy requirements?
Barley contains 1.5 Mcals DE per pound, so adding 3 to 4 lbs of barley to the cow’s ration during cold stress would meet the additional needs. Cows that are not on a grain ration prior to the cold weather may experience rumen upset if more than 4 lbs of grain is introduced into the diet at one time.
