BeefSC: A model for calculating optimal stocking rates and costs of beef. Description of model (v. 1.0) and input data for application on Brazilian beef production

This report documents BeefSC (Beef Stocking-rate and Cost model), a spatially explicit framework for estimating optimal cattle stocking rates, beef yields, and production costs across Brazil under four stylized beef production systems spanning extensive to semi-intensive management. It combines a biophysical stocking-rate optimization module with an enterprise cost module to translate pasture growth, herd dynamics, supplementation, and feedlot finishing into pixel-level cost and output estimates. The document includes full model description, equations and parameters, input datasets, and results from the Brazilian application.
