Effect of polymorphism in the 5’ promoter region of the TG gene on the milk production traits of Polish Holstein-Friesian cattle
<b>The aim of the study was to determine the relationship between the occurrence of three different point mutations (257C>T, 335A>G and 422 C>T) in the promoter region of the gene encoding thyroglobulin (causing polymorphism) and the milk production traits of cattle. The research was...
