The present study aimed at comparision of three methods of measuring the technical efficiency: Deterministic Frontier Production Function (DFPF), Data Envelopment Analysis (DEA), and Stochastic Frontier Analysis (SFA). Data were collected from 17 broiler Slughter-house Units (SHU) during 1378 to 1380 in Tehran province and then were measured the technical efficiency for each of SHU using each Methods. The Results of this study indicated that: 1) The different methods Results were not significantly different, in other word the value of efficiency was independent of the used methods for measuring the technical efficiency of SHU. 2) The Correlation between the value of technical efficiency was too high. Therefore, the ranking of SHU was independent of the methods used for measuring the technical efficiency. 3) The Sensitivity analysis test of omitting the outliers indicated that the value of technical efficiencies before and after omitting were not significantly different.
