Abstract

                                A study was undertaken in dairy to assess the energy use pattern in Perumalpatti village of Thoothukudi district. The objectives of the study were to collect the data on energy use pattern in dairy, to workout the energy consumption for different operations and to study the energy economics. Simple percentage analysis and average analysis for different energy sources were utilized for interpreting the results. The average total operation-wise energy consumption was found to be 14.71 MJ per farm holding and total energy consumption was found to be 667.66 MJ per farm holding. The major energy contributing source was dry fodder (85 %) and green fodder contributed only 2.26 per cent. The total output energy per farm holding was 335.99 MJ. The output-input energy ratio was 0.5. The specific energy consumption was 31.43 MJ per liter of milk.
