Esfanjari Kenari Assistant Professor of Agricultural Economics, Faculty of Agricultural Sciences, University of Guilan, Rasht, Iran Journal Article 1970 01 01 Energy of inputs is a necessity<br />of life for human beings all over the world due to its function in<br />strengthening the security and contentment of the people. This study was focused on economics of energy on<br />laying hen rearing units in Iran. The data of this study obtained<br />from a sample of 354 farms that were taken from an industrial farm census<br />conducted by the Statistical Center of Iran in 2016. Investigation of energy efficiency in the laying<br />hen rearing industry indicated that index of energy productivity in the first<br />group (the provinces of East Azarbaijan, West Azarbaijan and Hamadan) and the<br />second group (the provinces of Tehran, <br />Qom and Markazi) are 47 and 48 kg/MJ and specific energy ratios for these two groups were 40.74 and 29.96 MJ,<br />respectively. Result of this study showed that energy efficiency was low and energy perishes was high in this industry. Therefore, modern and well<br />established scientific practices can be used to improve energy efficiency<br />and reduce energy losses.
