The study was carried out on 12 lactating Murrah buffaloes during early lactation of 50-70 days at the Institute herd during extreme summer. Experimental buffaloes were kept under mist and fan (group I) or allowed to wallow in a pond from 11.00 A.M. to 4.00 P.M. daily (group II). Blood and milk samples were collected from both the groups on periods 1, 2, 3, 4, 5, 6 & 7 (at 3 day interval) and levels of Ca, P, Fe, Cu and Zn were estimated. The levels of Ca, P, Cu and Zn in milk were not significantly different in both the groups. In plasma also, the levels of Ca, P, Cu and Zn were not significantly different between groups, however, milk Fe varied (P<0.01) between groups. The study indicated that mineral levels were not significantly different under mist+fan and wallowing.
