The main issue that arises in this context is the known existence of a positive correlation between the risk of mastitis and lactation performance due to selection. The transcriptome-wide association study (TWAS) approach endeavors to combine the expression quantitative trait loci and genome-wide association study summary statistics to decode complex traits or diseases. Accordingly, we used the <span>farmgtex</span> project results as a complete <span>bovine</span> database for mastitis and milk production. The results of colocalization and TWAS approaches were used for the detection of functional associated candidate genes with milk production and mastitis traits on multiple tissue-based transcriptome records. Also, we used the <span>david</span> database for gene ontology to identify significant terms and associated genes. For the identification of interaction networks, the <span>genemania</span> and <span>string</span> databases were used. Also, the available <i>z</i>-scores in TWAS results were used for the calculation of the correlation between tissues. Therefore, the present results confirm that <i>LYNX1</i>, <i>DGAT1</i>, <i>C14H8orf33</i>, and <i>LY6E</i> were identified as significant genes associated with milk production in eight, six, five, and five tissues, respectively. Also, <i>FBXL6</i> was detected as a significant gene associated with mastitis trait. <i>CLN3</i> and <i>ZNF34</i> genes emerged via both the colocalization and TWAS approaches as significant genes for milk production trait.
