Comparative efficacy of three different heat tolerance indices for thermo- adaptability during heat stress in bovines

摘要

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