Author(s): P Mayengbam, RC Upadhyay and TC Tolenkhomba
Abstract: A study was carried out to find out the effect of temperature humidity index on neutrophil lymphocyte ratio of Karan-Fries heifers in five different periods based on maximum ambient temperature/minimum ambient temperature (Tmax/Tmin) viz. P1: <20 oC/<10 oC; P2: >20 oC/<10 oC, P3: >25 oC/<15 oC; P4: >35 oC/<20 oC and P5: >35 oC/>20 oC. The study investigated the effect of acute thermal exposure on neutrophil lymphocyte ratio of Karan-Fries heifers. Exposures were done at 40 oC and 50% RH and 45 oC and 50% RH in climatic chamber for 4 consecutive hours. Neutrophil leukocyte ratio was calculated from differential leukocyte count of blood smears stained with Leishman’s stain. Neutrophil lymphocyte ratio of Karan-Fries was stable throughout the year in natural climatic condition. Exposure I and Exposure II in climatic chamber caused no significant change in neutrophil lymphocyte ratio of Karan-Fries. The study revealed good thermotolerance of Karan-Fries cattle both in natural climatic condition and thermal stress in climatic chamber.
