This paper deals with tactical planning decisions for breeding farms producing piglets through
a linear optimization model. A medium-term planning horizon based on weekly periods is
considered. The proposed model maximizes the profit of the farm and takes into account
sow herd dynamics, housing facilities, reproduction management, available stocks and a target
quota of a weekly number of farrowing to integrate piglet production into the pig supply chain
management. As result, an optimal replacement policy of sows and a scheduling of purchases
of gilts during the whole planning horizon are provided. The model is solved using the algebraic
modeling language ILOG OPL 6.1 with CPLEX 11.2 as the linear optimization solver. The article
also discusses results obtained from a sensitivity analysis performed to assess the
suitability of the model approach and the benefits of representing real variability over time
against time homogeneity. In addition, the analysis and results presented lead to better understand
sow herd dynamics over a finite time-horizon and corresponding performance.
