Brazilian pig farming, despite its relevance in global pork production, faces significant economic challenges, especially among independent producers, due to price volatility and high production costs. The objective of this dissertation was to develop and apply a simulation model based on contribution margin to estimate the optimal slaughter weight of pigs, aiming to maximize profitability and promote the sustainability of the activity. The research was structured into two scientific articles. The first proposed an economic simulation model that integrates variables such as piglet price, feed cost, other variable costs, and selling price, evaluating market scenarios (optimistic, stable, and pessimistic) to determine the slaughter weight that maximizes contribution margin. The second deepened the analysis by considering the effect of zootechnical performance on the optimal slaughter weight, using data from the Brazilian Tables for Poultry and Swine (2024 edition) to fit growth and feed intake curves for pigs with different performance levels. The results indicated that both economic conditions and productive performance directly influence the contribution margin and the strategic definition of slaughter weight. Favorable scenarios and high-performance animals allowed for an extension of the production cycle, resulting in significant economic gains. This work provides practical, evidence-based tools to support decision-making in pig farming, highlighting the importance of integrating economic management and technical knowledge in the formulation of efficient production strategies.
