dc.description.abstractInbreeding is generally associated with a reduction in production and profitability. Therefore, it is essential that it be monitored and kept under control. The purpose of this study was to calculate the inbreeding coefficient for Holstein Friesian cattle registered in the database of the Cattle Breeders' Associations of Turkey (CBAT). In this study, pre-herdbook and herdbook databases were combined. The database consisted of 6,935,005 individuals born between 1962 and 2012. Inbreeding coefficients were calculated using Wright's method, and ranging from zero to 43.75% with a mean of 0.0012 and standard deviation (SD) of 0.01273 for all animals, and considering the inbred animals, the mean inbreeding coefficient was 0.0106 and standard deviation was 0.03272. The average inbreeding of all animals born in the population in 2012 was found to be 0.0022. In the population, the proportion and the number of inbred individuals increased over the years, while the mean inbreeding coefficient decreased. This could be due to the fact that gene flow in the population from different countries was considerably high, and pedigree information was taken into account while importing sperm and live animals (both heifers and bulls).tr_TR
