Heat stress is a significant challenge in dairy cattle, impacting their physiological well-being, productivity, and overall health. Understanding the gene expression profiles in heat-stressed dairy cattle is crucial for developing effective management and breeding strategies. This study investigates the changes in gene expression in response to heat stress, focusing on the molecular mechanisms and key genes involved, and explores the physiological, behavioral, cellular, and molecular responses of dairy cattle to heat stress, with particular attention to heat shock proteins (HSPs) and their roles in maintaining cellular homeostasis. Through techniques such as RNA sequencing, quantitative PCR, and bioinformatics analysis, this study provides a comprehensive overview of the gene expression changes under heat stress conditions, highlighting the impact on metabolic pathways and immune responses. A case study is presented to illustrate the practical implications of these findings for dairy production, emphasizing the potential for genetic selection for heat tolerance and the importance of appropriate nutrition and management practices. This study concludes with recommendations for future research, addressing unresolved questions and exploring emerging technologies that could enhance our understanding of gene expression in heat-stressed dairy cattle.
