Competency Area 6: Nutrient Management and Planning

PO 51. Understand the importance of precision feeding for whole-farm nutrient management.

The largest amount of nutrients imported by dairy and livestock farms tends to be from feed imports.  Better forage quality and matching diets with animal needs can improve animal nutrient use efficiency, reducing nutrients in manure and thus reducing feed nutrient imports, improving the farm's nutrient balance.
