increasing the population and scarcity of resources, shows the importance and necessity of productivity. Considering the productivity of the agricultural factors in Iran being the biggest economic sector in Iran. Enhancement of interest is required to know the components and investigate the changes in the direction of achieving economic development. Productivity change is a crucial aspect of structural change .studies show that most of the people in the world, and especially developing countries suffering from scarce of protein, so animals protein has important role in humans health and life and its quality and amount must be optimal. the poultry industry is the one of the most important sectors in the agricultural and is the one of the important protein source because of that in large amount of investments that have been done in the field of poultry farms. therefore, for improving productivity requires to understanding of components and studying its changes can lead to economic development.

The objective of the article is to assess comparsion and analysis of total factor productivity of broiler chicken production. This article estimated total factor productivity (TFP) change and its components technological change and efficiency change.so decomposed these changes into technical change, technical efficiency change, and scale and mix efficiency change in broiler chicken farms by using Fare-primont TFP indexes For this. The Färe-Primont Indices based on non-parametric Data Envelopment Analysis (DEA) Productivity measures of a decision making unit (DMU) that can be expressed as the ratio of an output quantity change index on an input quantity change index, can be referred to as ‘multiplicatively complete’ and does not require price information. Indeed, it relies to on non-linear weighting functions and normalized shadow) prices. in this way Input and output quantity data were included for labor, bird seed, fuel, and chicken meat using records from the results of a sample survey of industrial broiler chicken farms in the provinces of Iran during 1994-2015.

Results in the Broiler chicken farms indicated that during the period, Total Factor Productivity index of chicken broiler has been increased in some years. The annual average growth of total factor productivity in broiler farms in Iran broiler farms is 10.3%, which is different in provinces. Markazi province has the highest TFP equal to (0.88). and Bushehr and Hormozgan have the lowest TFP respectively. the average of efficiency of productivity (TFPE) is also less than one and equal to 0.60 that shows the efficiency of productivity efficiency of the total factors productivity has decreased during the years which compared with the base year. Output-Oriented of (OSE) amount of scale efficiency is smaller than one in this study shows although have not been efficient but there is no significant difference with the number one (appropriate efficiency). The highest of scale efficiency is (0.98) belongs to Kerman and Yazd provinces, as well as has the lowest scale efficiency among the studied provinces is in Bushehr Province (0.74). And the findings show that technology changes are the most effective factor in increasing the total factor productivity factors in broiler chicken farming in Iran provinces. Finally efficiency and total factor productivity among the studied provinces are different and there is a direct relationship between low productivity and low efficiency.

the results indicate that for achieving of high total factor productivity in Broiler chicken farms in Iran, we need more attention to technology in this part. For example, using of pure breeds And effective can improve conversion factor of the birds seed. Investment by government and private sector can improve the scale of the Broiler chicken farms units in Iran. as the fuel uses the most consumption among the inputs in this study. According to results scarcity of fuel and using birds seed over of optimal, so wasting can be stopped by increasing the efficiency of heating equipment in Broiler chicken farms. it this way it found that technical efficiency was a determinant factor and resulted in a decreasing in the performance of well - studied ones. also low efficiency in some provinces is a serious problem. and it is suggested to increase their efficiency by determining the optimal size of their performance in provinces with low - scale efficiency.
