Abstract:

Mastitis is one of the more harmful diseases in dairy farming, which seriously affects the health of cows and dairy safety, and therefore requires timely preventive and control measures. Currently, there are problems such as inefficient diagnosis and unclear explanations of the pathogenesis of mastitis in dairy cows. With the rapid development of high-throughput sequencing technology, genomics, epigenomics, transcriptomics, proteomics, and other omics techniques have been gradually applied to dairy mastitis-related research, which promotes in-depth knowledge of the disease. This paper reviews the current status and research progress of the application of omics techniques in the pathogenesis and diagnosis of mastitis in dairy cows, aiming to provide a reference for scientific understanding and reducing the incidence of mastitis. By analyzing the multifaceted mechanism of mastitis in dairy cows, key regulatory pathways, and potential biomarkers, such as proteins like CHI3L1, LBP, GSN, GCLC, C4, and metabolites like lactic acid and tyrosine, were revealed, which can provide knowledge for the unveiling of mastitis and a new way for intervention and treatment. However, when applied in production, histology technologies still face challenges such as high cost and technical threshold. With the deeper integration and lower cost of multi-omics technology, it will help to discover more accurate biomarkers and gain insight into specific signaling pathways, providing a more scientific basis for the prevention, diagnosis, and treatment of mastitis in dairy cows.
