ASSESSING HEAT TOLERANCE IN CROSSBRED FEMALE CALVES: IBERIA HEAT TOLERANCE COEFFICIENT, BENEZARA COEFFICIENT OF ADAPTABILITY, AND DAIRY SEARCH INDEX
J. Girish Kumar , Ph.D. Scholar., Animal Physiology Division, National Dairy Research Institute (Ndri), Karnal, IndiaAbstract
This study aimed to assess the heat tolerance of crossbred female calves using three different indicators: Iberia Heat Tolerance Coefficient, Benezara Coefficient of Adaptability, and Dairy Search Index. Heat stress is a major concern in livestock production, particularly in regions with high temperatures. Understanding the heat tolerance of animals is crucial for their well-being and productivity. In this study, a total of X crossbred female calves were evaluated for their heat tolerance using the aforementioned indicators. The results indicated a significant variation in heat tolerance among the crossbred calves, as reflected by the different coefficients and indices. These findings provide valuable insights into the selection and management of crossbred female calves for improved heat tolerance, leading to enhanced productivity and animal welfare in heat-stressed environments.
