Modelagem e simulação de sistemas de ciclo completo na produção de bovinos de corte

Abstract

This work deals with modeling and simulation in system dynamics in beef cattle farming to understand the importance of animal production indicators and estimate economic performance, over time, through the herd structure with a complete cycle. This study aims to develop a model for the dynamics of full-cycle systems in beef cattle farming to estimate general productivity from technical production coefficients through causal loop diagrams and the direction or magnitude of changes in the results. These can be estimated using birth and death rates. System efficiency also includes stocking rate. Through a systematic literature review, it was possible to identify the methodologies and computational tools used in modeling and simulations of breeding, recreating and complete production cycle systems. The results showed that depending on cost and revenue, an increase in birth rates can favor productivity and profit per hectare. Modeling and simulation sought to quantify the magnitude of the effects of the indicators used over time, considering maximum investment limits or costs
