This study applied a non-parametric method in determining the efficiency of farmers, discriminating efficient farmers from inefficient ones, and identifying wasteful uses of energy in order to optimize the energy inputs for broiler production. Furthermore, the effect of energy optimization on greenhouse gas (GHG) emission was investigated and the total amount of GHG emission of efficient units was compared with inefficient units. A total sample size of 55 broiler farmers were selected from Kaduna State viz. multi-stage sampling technique. Total energy used in various operations during broiler production was 77916.14 MJ (500bird)-1. Results revealed that 63% of producers were technically efficient, while 43 producers under PTE were identified efficient (79.6%). Additionally, it was concluded that 1.38 percent [1071.54 MJ (500birds)-1] of overall input energies can be saved if the performance of inefficient farms rose to a high level. Finally, comparative results of GHG emissions revealed that the amount of CO2 emissions in efficient units was less than inefficient farms.
