Intended Outcomes

The participants will

  • Develop a general understanding of nitrogen (N)(protein) and phosphorus (P) metabolism in feedlot cattle.
  • Learn the recommended N and P requirements for feedlot cattle to minimize overfeeding of these nutrients.
  • Develop an understanding of potential dietary strategies that will maintain or maximize animal performance and minimize total nutrient excretion.

Contents

Activities

Participants will:

  • Calculate late the amount of N and P excreted by feedlot cattle.
  • Evaluate the effects of ration formulation changes on N and P excretion..
