is known for its tolerance of coarse grains, adaptability, high temperature, humidity, and disease resistance. Primarily, cattle are raised for their meat and milk, and pinpointing genes associated with traits relevant to meat production can enhance their overall productivity. The aim of this study was to identify the genome, analyze the evolution, and explore the function of the gene family in to provide a new molecular target for breeding in meat-quality-trait cattle. In this study, 44 genes were identified from the genome database of five species using bioinformatics technology, indicating that the genetic relationships of bovids were similar. The and protein sequences of the five animals were highly consistent. In general, the gene of the buffalo corresponds to the domestic cattle. In summary, there are differences in affinity between the family genes of buffalo and domestic cattle in the , , and subfamilies. We believe that has an effect on the growth traits of buffalo and domestic cattle. The gene is conserved in the evolution of buffalo and domestic animals and may be a key gene regulating the growth of B. taurus. The subfamily affects coat color, reproductive performance, and milk production performance in cattle. The subfamily had an effect on the milk fat percentage of B. taurus. The results provide a theoretical basis for understanding the evolutionary, structural, and functional characteristics of the family members of and for molecular genetics and the breeding of meat-production species.
