Abstract
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 (zinccitrate
glutamate) in dairy cows.
