“…To help mitigate the adverse impacts of thermal stress on cattle productivity, some strategies can be implemented, including genetic selection, modification of the environment, and nutritional intervention [10]. Besides, scientific techniques such as cooling systems and sprinkler treatments have been developed to reduce the adverse impact of heat stress on animals [11,12]. It has been reported that within-breed genetic variation exists for thermotolerance, and thus,which allowing genetic selection for improved thermotolerance and may increasing animale the resilience and well-being of animalswelfare [13].…”

Thermal stress due to extreme changes in the thermal environment is a critical issue in cattle production. Many previous findings have shown Many evidences showed a decrease in feed intake, milk yield, growth rate, and reproductive efficiency of the cattle when subjected to thermal stress. Therefore, sSelecting thermo-tolerant animals are is therefore the main primary goal of the efficiency of breeding programs to reduce those adverse impacts. The recent advances in molecular genetics have provided significant breeding advantages that allow the identification of molecular markers in both beef and dairy cattle breeding, including the use of marker-assisted selection (MAS) as a tool in selecting superior thermo-tolerant animals.Single-nucleotide polymorphisms (SNPs), which can be detected by DNA sequencing, are desirable DNA markers for MAS due to their abundance in the genome's both coding and noncoding regions of the genomes. MTill date, many SNPs in some genes (e.g., HSP70, HSP90, HSF1, EIF2AK4, HSBP1, HSPB8, HSPB7, MYO1A, and ATP1A1) in various breeds of cattle have been analyzed to play have key roles in many cellular activities during thermal stress and protecting cells against stress, thereby beingmaking them potential candidate genes for molecular markers of thermotolerance. TIn this review , we highlighted the associations of SNPs within these genes with thermotolerance traits (e.g., blood biochemistry and physiological responses), which could imply suggesting their potential use as MAS in thermotolerant cattle breeding.
