Continuous recording of core body temperature is the major requisite to study thermodynamicsofthebodyindetail.Information ondynamicdiurnal corebody temperaturehelps to formulate suitable thermal stress alleviating measures in livestock production. There are several electronic loggers available to record body temperature continuously. In this study a small and convenient Thermochronibutton was used to record vaginal temperature of dairy cattle subjected to thermal stress alleviating measures in winter and summer. It provided accurate and continuous data to analyse the effect of stress relieving measures and season on core body temperature of dairy cows.
Keywords: Dairy cattle, core body temperature, temperature logger, Thermochronibutton
