Abstract

Instructional Dairy Farm at Pantnagar University was studied for evaluating its energetic efficiency, an important
measure to evaluate the functioning of a production system. The total organic inputs and outputs of the dairy farm
were converted into their respective energy values. Of the total energy flows involved in the dairy farm, 72.6% was
the input energy suggesting that most of the energy flow in the dairy farm takes place through feeds. Of the total
energy output, dung accounted for 54.83% and milk 44.86%. Only 0.31% of the total output energy was contained
in the new born calves. The energy balance of the dairy farm reflected that dung was the most important product,
though milk was regarded as most valuable product as it is used for direct human consumption. Gross energetic
efficiency of the farm worked out to be 37.7%. This reflects that 62.3% of the total energy was being used for nonproductive purposes (methane production or others).
