Abstract. The aim of this study was to estimate the associations between the FABP3 genotypes and the growth traits (body weight at 210 days of age, average daily body weight gain to 210 days of age, withers height, sacrum height, chest girth) as well as longevity in 98 Simmental and 86 Salers cows. The analysis of the first calving was also carried out. Statistically significant associations between the FABP3A/G polymorphism and the body weight at 210 days of age, daily body weight gain to 210 days of age and longevity in Simmental cows were found; higher values of these traits were observed in cows with the G allele. No significant associations were found between the above polymorphism and the all analyzed traits in Salers cows. The study results indicated that the selection for the animals with the G allele might contribute to an increased some weight traits and longevity in Simmental cows. Additionally, the largest number of individuals with this allele were characterized by easy calving. It is necessary to continue research on the larger groups of animals.
