Análise envoltória de dados para avaliação da eficiência da avicultura familiar em Alagoas

Abstract

This thesis is addressing DATA ENVELOPMENT ANALYSIS FOR ASSESSING THE EFFICIENCY OF FAMILY POULTRY AT ALAGOAS, whose main objective was to evaluate the technical efficiency of the farmers included in the Family Poultry Program (PAF) in the municipality of Santana do Ipanema - Alagoas. Poultry was selected due to the heterogeneity of the activities performed within the family farm, which is characterized by its complexity in relation to production and trading, making the sector historically dependent on the welfare policies of the government. Given this context, the main subjects addressed in this work are: PAF family farmers, who received technical-managerial guidance, are effectively differentiated? And how services such as technical assistance and rural extension (Ater) may have influenced this differentiation? The hypothesis is that producers who received technical support, together with managerial guidance, are more technically efficient than those assisted by the conventional Ater public. Results were obtained by means of statistic tests and Data Envelopment Analysis (DEA). Statistic tests (normal test, t test and chi square test) were used in order to verify the average of the studied sample, while non parametric model DEA, through computer tool SIAD, provided the necessary results needed for the technical efficiency comparison of the producers studied. The results obtained confirmed the central hypothesis of this dissertation, pointing out that family farmers who have received technical-managerial guidance were actually more technically efficient than those who have not.
