The present study assesses the relationship of meteorological variables with physiological stress parameters. Respiration rate was continuously measured (RR) using Physiological monitor with improvised facemask. Rectal temperature (RT) was continuously measured using in- dwelling thermo couple probes attached with data acquisition system. The experiment was conducted in the Livestock Farm of Kerala Veterinary and Animal Sciences University, Mannuthy, Thrissur, Kerala. Experimental animals included eight, six months to one year old crossbred female cattle. The study was conducted for a period of 120 days in two seasons, season I and season II covering maximum Temperature Humidity Index (THI) and minimum THI seasons (Season I: 24th March 2017 to 25th May 2017 and Season II: 15th December 2017 to 13th February 2018).
