Abstract: The effects of cow's genotype for growth hormone receptor (GHR) were determined on milk production traits of the Polish Black-and-White (BW) cattle. It was shown that GHR genotypes significantly influenced most of the dairy traits studied. Cows of the RFLP-NsiI -/- genotype of GHR produced more milk with higher content of milk components, including fat, protein, and lactose than those with +/+ genotype. The heterozygous +/- genotype at RFLP-AccI appeared superior with respect to two milk composition parameters - gross energy and total solids. The combined GHR genotypes (CGGs) 2213 and 1113 were clearly favourable for most traits under study. Cows carrying the 2213 genotype combination produced daily more fat corrected milk, fat, protein and lactose than other genotypes, and the milk of 2213 and 1113 cows contained significantly more total solids, protein, and fat.
