Genetic basis of heat tolarance in cattle

Abstract:
Now-a-days, heat stress is a major problem in cattle population by impairing cattle health and production ability which indirectly affects the economy of farmers. The cellular heat stress (HS) response is one component of the acute systemic response to HS. Gene networks within and across cells and tissues respond to environmental heat loads above the thermoneutral zone with both intracellular and extracellular signals that coordinate cellular and whole-animal metabolism. Activation of these systems appears to be initiated at skin surface temperatures exceeding 35 °C as animals begin to store heat and rapidly increase evaporative heat loss (EVHL) mechanisms. Genes regulating heat tolerance in cattle should be known for selection of better animals in future.
