The NDDB tested a ration balancing programme in six states. As part of the programme field studies were conducted in different parts of the country including the Junagadh district of Gujarat State with balanced rations worked out for the milch animals.

Twenty-two lactating Jaffarabadi buffaloes and five Gir cows were selected for the study. An average reduction of 17.99% and 17.25 % methane emission, in terms of g/kg milk yield was observed in lactating buffaloes and cows respectively, which was significantly (P<0.01) lower from the baseline emissions. Ration balancing also significantly improved the milk yield (kg/day) and milk fat (%) in both the species.
