Thermotolerance and adaptation strategies in Indian Desert Sheep Breeds: A review
Authors

Abstract
The arid and semi-arid regions of India constitute approximately 31.7%
of the total geographical area, where indigenous sheep breeds have evolved
remarkable adaptive mechanisms to withstand extreme thermal conditions. This
doctrinal and analytical study examines the physiological, morphological, and
behavioral adaptations of native sheep breeds inhabiting arid zones, with
particular emphasis on their resilience to heat stress. Through comprehensive
analysis of existing literature, breed characteristics, and stress response
mechanisms, this research illuminates the inherent thermotolerance capabilities
of Indian sheep populations. The findings underscore the significance of
indigenous genetic resources in sustainable livestock production systems and
climate-resilient agriculture. This investigation reveals that breeds such as
Marwari, Magra, Chokla, and Malpura demonstrate superior adaptive traits
including reduced metabolic heat production, enhanced evaporative cooling
mechanisms, and specialized coat characteristics that facilitate survival in
hostile environments where ambient temperatures frequently exceed 45°C during
summer months.
