Description Thermal stress in India is one of the major constraints affecting dairy cattle productivity. Every attempt
should be made to ameliorate the heat and calving related stress in high producing dairy cows for higher
economic returns. In the current study, inorganic zinc was tried to alleviate the adverse effects of thermal
stress in periparturient cows. Twelve cows, six each of Sahiwal and Karan Fries (KF) in their second parity
with confirmed pregnancy were chosen for the experiment. The blood samples were collected peri parturiently on three occasions viz. 21, 0 and þ21 days relative to calving. The in vitro study was
conducted after isolating peripheral blood mononuclear cells (PBMC) from whole blood. The cultured
PBMC were subjected to three different levels of exposures viz. 37 C as control, 42 C to induce thermal
stress and 42 C þ zinc to ameliorate the adverse effects of high temperature. Heat shock lead to a sig nificant (P
