Factors that might be considered under the topic offeeding management include:Ration formulation,Ration evaluation (nutrient analyses by a lab),Routine forage and grain analyses,Adoption of silage best management practices,Use of production enhancers (rBST for dairy),Phase feeding,Drinking water quality,Bunk management,Amino acid supplementation,Low phytic acid corn, andEnzymes.WIN 2 ME - “Feed Management Education for the Agricultural Professional”

Nutrient Management Needs to be consideredat the Whole Farm Level and BeyondExportedManureMost dairies arenet importers of nutrients
