Technical Abstract: In the past three decades, animal production in the United States has been moving towards consolidation. This study profiles the animal density, manure production, and antibiotic usage in the Ogallala Aquifer region that covers eight states in the Central United States. The amount of manure was estimated by county along with major nutrients such as nitrogen and phosphorus using state-specific manure-production and nutrient composition charts provided by agricultural extension services. Antibiotic use was estimated by county using the industry recommended doses per animal. Also, a relationship between animal density and crop land acreage was evaluated. This information is useful for researchers involved in developing renewable sources of energy from manure; and air and water quality.
