We’ve been feeding the milk cows a TMR for many years.  Until last fall, it was fairly complex, including a specially formulated multi-ingredient commercial blend.  Last summer we made a decision to simplify the ration to include only corn and corn silage we raise, alfalfa hay we were purchasing from a neighbor, dried distillers grains (DDGs) and soybean meal.  Now market conditions have led us to add a little complexity.
