The Kerr Center’s beef cattle program has these goals:

  • balance production level with production cost
  • forage-based: grazing management maintains soil fertility and promotes plant diversity
  • training the next generation of ranchers

1st principle of sustainability: create and conserve healthy soils

“Grass farmer plan”: high-density rotational grazing fosters health from the ground up:



Many animals for a short time in a small area


  • soil: concentrates animal manure/urine for fertility; reduces compaction
  • plants: keeps plants vegetative and growing; increases diversity; reduces weeds
  • animals: fresh and nutritious forages; reduced parasites
  • rancher: reduces costs; increases profits
