摘要：
The aim of this study was to estimate the relations between the leptin combined genotypes versus milk performance traits (yields of milk, protein, and fat, as well as protein and fat content). The investigation was performed on 860 Black-and-White cows with a different share of the of Holstein-Friesian genes, kept in Pomerania. Frequencies of the LEP-C3100T/Sau3AI genotypes were: CC/AA - 0.315, CT/AA - 0.272 and CC/AB - 0.142. The frequencies of the remaining genotypes did not exceed 0.100. Statistically significant (P <= 0.01) relation between the leptin combined genotypes (LEP-C3100T/Sau3AI) and milk, protein, and fat yield were observed. These traits were significantly higher in the CC/BB genotype cows.
