Abstract: In this study the effect of leptin gene single nucleotide polymorphism (SNP) on cattle internal environment indicators were evaluated. In experiment 58 Czech Pied bulls divided in three groups (TT, CT and CC) according to leptin SNP were investigated. Serum leptin, insulin, thyroxine, triiodothyronine, triacylglycerols and non-esterified fatty acids concentrations were measured. No significant differences in serum T3, T4, TAG and NEFA concentrations between experimental groups, were found. Significantly higher concentration of serum insulin was recorded in group of TT bulls compared to CT a CC genotype. No effect of SNP of leptin gene on leptin serum concentration was recorded. No significant correlations between monitored hormones and metabolites in serum of Czech Pied bulls were found. Some differences in comparison with results found in other studies could be given by differences in fattening capacities particular breeds.
