Dry period in buffaloes is critical. Negative effects of heat stress during this period may be momentary as well as get accumulated and carried over to subsequent lactation. Present study was conducted to assess effect of mitigating heat stress in dry period of Surti buffaloes on erythrogram, leukogram and neutrophil to lymphocyte ratio during subsequent lactation. Twelve dry Surti buffaloes in their advanced gestation were selected and divided into control (n=6) and treatment (n=6). Mitigation of heat stress by shed modification was done only during dry period for treatment buffaloes. Treatment shed had fan for ventilation, roof whitewashed with microfine lime and 1/3rd of open paddock covered with 75% green net. Blood sample was collected at -8, -3, +1 and +3 wk of parturition and analysed for erythrogram, leukogram and neutrophil to lymphocyte ratio. Heat ameliorative measures in shed were successful in providing thermal comfort by reducing temperature, relative humidity and THI of shed. At -3 wk (P≤0.05), +1 wk (P≤0.01) and +3 wk (P≤0.05) Hb concentration and at -3 wk (P≤0.05) TEC and MCHC were lower in control buffaloes. TLC was significantly lower in control group of buffaloes at +3 wk (P≤0.05). In control group neutrophil % was significantly higher at -3 wk (P≤0.05) and +3 wk (P≤0.01) whereas simultaneously lymphocyte% was significantly (P≤0.05) lower at the same time. Neutrophil to lymphocyte ratio at -3 wk (P≤0.05) and +3 wk (P≤0.01) was significantly higher in control group as compared to treatment. These results indicated presence of stress in control buffaloes. Providing thermal comfort improved profile of erythrogram and leukogram and optimized neutrophil to lymphocyte ratio. It was concluded that heat stress mitigation during dry period in buffaloes reduces immediate as well as carryover negative effects during subsequent lactation
