Abstract: The aim of our study was to detect the presence and concentration of leptin in different breeds of cattle by PCR and Real time PCR method. Blood of different breeds of bulls was used as biological material in our experiments: Slovak pied cattle (10 samples), Blondaquitane × Pinzgau breed (10 samples) and Holstein breed (10 samples). The presence of leptin was detected in all samples based on the results of molecular-genetic detection of leptin gene. The average concentration of leptinin 30 samples of beef cattle was 22.1477 μg.μl-1. Differences in leptin concentrations were statistically significant between Holstein breed and Slovak pied cattle and between Slovak pied cattle and Blondaquitane × Pinzgau breed.
