mitigation strategies have a major focus on use of renewable energy along with
adoption of energy efficient and environment friendly management methods to
improve the profitability of dairy farms. It is widely believed that livestock is
contributing largely to the emission pool. The methane emission from enteric
fermentation and improper manure management is often the focus of criticism. India
being figured fourth in the list of largest emitters, it is imperative that the Indian dairy
sector need to be monitored in order to evolve mitigation strategies. Hence this study
was intended to investigate the energy use pattern in a medium dairy farm as well as
the extent of GHG emission with a view to analyze the economic and environmental
advantage of producing renewable energy from anaerobic digestion of cattle dung. The
study was conducted at the Permangallur Dairy Farm at Pattambi, Palakkad district.
The energy use pattern in different sections of the dairy farm was observed using
standard techniques and an energy analysis was done. The total GHG emissions from
cattle (enteric fermentation and manure management) were analyzed by using the
GLEAM-i model of FAO. In the present study the total average input and output energy
were calculated as 37392.3 MJ and 5062 MJ per 1000 L of milk produced. Feed intake
had the highest share (97%) from total input energy, followed by electricity (2%). The
CH4 emission per cow was found as 322 g/day in the farm. The total CH4 emission
from manure management was found to be 41.36 g / head/ day. The total GHG emission
from electricity usage in the farm was 87.45 kg CO2 eq /cow/ year. The potential biogas
production was 27.8 m3 per day and only 8.6 m3 was used presently. It was inferred
that production of electricity with the available balance biogas of 19.2 m3 per day could
save electrical energy. Out of the total GHG emission of 3039.7kg CO2 eq /cow/ year
it was found that GHG emission can be reduced to 2952.2kg CO2 eq / cow/ year by
producing electricity from biogas.
