Present study was done on Crossbred Karan Fries (Holstein Friesian X Tharparker)cows (n=18) to evaluate the effect of boron supplementation on milk yield, milk composition and somatic cell count of milk during heat stress, cows were allocated to three treatments, viz, group 1 (n=6), group 2 (n=6) and group 2 (n=6) based on bodyweight, parity and estimated producing ability. All cows received basal feed (roughage and concentrate) based on ICAR feeding standards. Additionally, in group 2 and group 3, boron was supplemented at the rate of 250 ppm and 500 ppm, respectively. The plasma boron was estimated to be significantly higher in boron supplemented groups than control. The milk yield, milk Fat% and milk composition on weight basis (kg) has no significant improvement but other milk composition (viz, milk SNF, milk protein, milk lactose and milk total solids %) did differ significantly between the control and boron supplemented groups. Somatic cell count of boron supplemented groups was significantly low (p<0.05) than control, but there was no significant relationship between treatment groups. It is concluded that supplementing boron in diet improved the milk composition (%) and reduced the SCC of milk but no considerable improvement in milk yield was observed.
