An experiment was conducted to ascertain the efficacy of adding chelated zinc on milk production of lactating cows across various stages of lactation. Twelve cross-bred cows were selected from different locations of Alwar district of Rajasthan and randomly assigned to three groups for receiving either chelated or inorganic sources of zinc, organic zinc glutamate and inorganic zinc oxide (n=4). The experimental treatments include control, T1 - zinc-citrate glutamate (organic mineral @ 9.26g/cow/day) and T2 - zinc oxide (inorganic mineral @ 0.833g/cow/day). The cost effectiveness of zinc-citrate glutamate and zinc oxide supplements needed for producing 1 litre of milk was calculated using the data on total milk yield during the experimental period and cost of zinc supplements used. From the present study, it could be concluded that the group supplemented with organic zinc had better returns over other groups that feeding of organic zinc (zinc-citrate glutamate) in dairy cows.

Keywords: Zinc chelate, zinc oxide, milk yield and economics
