Expression of the Ovine Gene and the Relationship Between Its Polymorphism and Feed Efficiency Traits

In the mutton industry, feed efficiency traits have the greatest influence on the economic benefits of sheep raised in housing conditions. In this study, quantitative real-time PCR (qRT-PCR), Sanger sequencing, and KASPar methods were used to detect the expression levels of the B cell scaffold protein with ankyrin repeats 1 ( BANK1 ) gene and the relationship between its polymorphism and feed efficiency traits in Hu sheep. The qRT-PCR results showed that the BANK1 gene was extensively expressed in 10 tissues and it was expressed at remarkably higher levels in lymph than in other tissues ( p T, was detected in intron 4 of the BANK1 gene and proved to be remarkably associated with feed efficiency traits ( p
