The present study was carried out at the Livestock Research Complex, SRS, NDRI, District Bengaluru, India. Twelve indigenous Deoni heifers in their last month of gestation period were selected based on their dam’s lactation yield and lactation length. The cows were randomly divided into two groups of six each. The treatment group offered during transition period (-21 to +21 days respective to calving) with locally available trace minerals Cu (137 img), Zn (560 img), Mn (428 img), Se (1.5 img) and Vit-A (50,000 I.U), Vit-E (1100 I.U), β-carotene (300 mg) per animal per day, as per NRC (2001) recommendations, over and above the basal diet. The experimental cows were monitored for 180 days for lactation performance viz., average total milk yield, peak yield, days to reach peak yield. The supplementation showed no effect on any of the lactation parameters in Deoni primiparous heifers.
