dc.description.abstractThe present study was conducted to assess the adaptation capacity of castrated buffalo and crossbred male calves to the varying temperature humidity prevalent in central midlands of Kerala using physiological, haematological, growth, endocrine and genetic parameters. Ambient temperature, humidity, rectal temperature, pulse rate and respiratory rate were recorded daily. Relative growth rate and plasma volume were recorded at fortnightly interval. Haematological parameters and endocrine parameters were determined at biweekly interval. The temperature humidity index recorded throughout the year varied from 76.5 to 82.0. Rectal temperature remained invariable throughout the experimental period but respiratory rate and pulse rate exhibited a significant positive correlation (P<0.01) with temperature humidity index. A negative correlation was observed between temperature humidity index and relative growth rate, total erythrocyte count, haemoglobin concentration, volume of packed red blood cells and thyroid hormones of the experimental animals at P<0.01 level. While a positive correlation was observed between plasma volume and temperature humidity index in all the experimental animals. Cortisol levels remained consistent throughout the study period in buffalo and crossbred cattle calves. The rate of increase of plasma volume, respiratory rate and pulse rate were higher in buffalo calves compared to crossbred cattle calves. HSP90 expression showed significant (P<0.05) up regulation at a THI of 82.0 in all the experimental animals, however buffaloes showed a higher fold expression of HSP90 compared to that of crossbred cattle calves.en_US
