The purpose of this paper is to provide an insight into the methodology used in calculating coefficients for the livestock sector of the Center for Agricultural and Rural Development's (CARD) linear programming models.

These activities produce agricultural livestock commodities and nitrogen waste while requiring feed, water, energy, and capital.
