The present study was conducted on 45 Marathwadi buffaloes and 24 Deoni cows of different age groups from Instructional Livestock Farm Complex at COVAS, Udgir. Â Various physiological parameters like rectal temperature, pulse rate, and respiration rate of these animals were recorded during the summer season, and efficacy of three heat tolerance indices viz. Iberia heat tolerance indices, Benezara coefficient of adaptability, and Dairy search index were estimated. Highly significant (P<0.01) correlation was observed amongst the Benezara coefficient of adaptability and Dairy search index in Marathwadi buffalo as well as Deoni cows.
