Effect of Heat Stress on Physiological and Hemato-biochemical Profile of Cross Bred Dairy Cattle

DOI:Coming soon...


The present study was done to see the effect of heat stress on blood parameters in dairy cattle. Dairy cows of similar physiological status were selected. Blood samples were collected and analyzed based on the temperature-humidity index (THI). Blood samples were collected and analyzed for packed cell volume PCV(%), red blood cell count RBC count, white blood cell count (WBC) and hemoglobin (Hb). Significant rise in physiological parameters such as respiration rate (RR), pulse rate, was observed. Hematobiochemical parameters such as red blood cell count (RBC), (WBC), (PCV%), (Hb), Cholesterol, creatinine, ALT, AST, Cortisol and BUN were increased. From the present study it can be concluded that THI is a sensitive indicator of heat stress.
