Optimization of Production and Animal Transit in an Integrated Crop-Livestock System with no-Tillage

Authors: Vinicius Teixeira do Nascimento, Angel Ramon Sanchez Delgado, Sergio Drumond Ventura

Nowadays integrated crop-livestock production systems have been presented as a viable and sustainable alternative in economic, social and environmental terms. This work develops and implements a mixed integer programming model (MIXP) that represents or simulates numerically the optimum operational conditions of an integrated crop-livestock system with no-tillage (iCLS-NT), including animal transit. For the computational implementation of the model, data on the fitness of the live weight gain of each animal of the herd considered, in each period and area of the (iCLS-NT), (confinement, pasture and annual crop), as well as marginal net income of each crop and the costs per unit of food considered. In order to test the validity of the developed mathematical model, data were randomly generated. To solve each MIXP, we used the solver INTLINPROG in the software MATLAB. Thus, after the computational implementation, it was verified that the program meets all restrictions imposed, maximizes the weight gain of each animal, provides the best selection of annual crops and minimizes feeding costs in the confinement area.
