University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses feeding strategies to optimize dairy cow performance while minimizing negative environmental impacts.

Reducing N, P and K Excretion--The Challenge

Increasingly, our society demands livestock production systems that not only produce economic, high-quality food products, but also minimize negative environmental impacts. Feeding management has improved continuously and helps explain increases in milk production averages. The future challenge for dairy producers and nutritionists will be to properly formulate rations for high production levels while simultaneously minimizing the environmental impact of excessive N, P and K excretion in the urine and manure. A realistic approach will be to keep formulation …
