ABSTRACT
The aim of this study was to estimate the relations between the LEP/HphI, LEP/Sau3AI genotypes vs milk performance traits (yields of milk, protein, and fat, as well as protein and fat content) in 905 Polish Black-and-White cows, kept in Pomerania. The frequencies of LEP/HphI genotypes were: AA, 0.582; AB, 0.364; BB, 0.054. The frequencies of LEP/Sau3AI genotypes were: AA, 0.638; AB, 0.189; AC, 0.137; BB, 0.015; BC, 0.013, and CC, 0.008. Statistically significant (P≤0.01) relations between the leptin genotypes (LEP/HphI, LEP/Sau3AI) and milk, protein and fat yields were found. These traits were significantly higher in the LEP/HphI AA and LEP/Sau3AI BB genotypes.
