              Abstract
              
              
              
              Effect of supplementation of Zinc, Copper and Levamisole on 
              incidence of subclinical mastitis was studied. The level of zinc 
              increases significantly after supplementation and 75% animals was 
              recovered. However in copper supplemented animals (12) only two 
              animals showed complete recovery. None of the animals in Zinc and 
              Copper supplemented group developed clinical mastitis. In 
              levamisole supplemented group, 50% cows remained in subclinical 
              state while 50% converted in clinical mastitis. So, the zinc 
              supplementation is better over other two supplementation.
