Abstract

The objective of this study was to determine fattening performance data for Charolais, Limousin and Blonde d’Aquitaine beef cattle and associate these data with NPR2 gene 8:g.59961937 T>C (rs208158047) mutation. Experiments were conducted with 176 beef cattle (77 Charolais, 66 Limousin and 33 Blonde d’Aquitaine) at nine months of age. Experiments lasted for 9 months and animals were slaughtered at the age of 18 months. Cattle body weights were determined at four different periods: beginning of fattening (d0), 60th day of fattening (d60), 120th day of fattening (d120) and at the end of fattening (sw). In terms of rs208158047 mutation of Charolais, Limousin and Blonde d’Aquitaine breeds, TT and CT genotypes were identified, and CC genotype was not encountered. The association of average daily gain (ADG) in d0-d60, d0-d120 and d0-sw periods with the genotypes of rs208158047 mutation was found to be significant (P<0.05). Greater ADGs were observed in rs208158047-CT genotypes compared to rs208158047-TT genotypes. These results indicate that the selection of bovine NPR2 gene could be used to ensure the breeding direction for growth related traits of the beef cattle.
