Popis:	Reducing overfeeding of CP and phosphorus (P) is an effective method to reduce excess nutrient excretion by dairy cows. However market conditions frequently cause ingredients that are counterproductive to this goal to be the most economically attractive source of protein and energy. Less expensive feeds such as dried distillers grains and corn gluten feed are high in P or high in both CP and P. A linear program (Formulate2, Central Valley Nutritional Associates, Visalia, CA) was used to determine the effect of formulating rations for
