Slavonian-Syrmian Podolian cattle is one of the three autochthonous breeds in Croatia. After three decades of implementation of conservation measures, it is still in a critically endangered status. The objective of this work is to determine the population parameters based on pedigree records. The ENDOG v4.8 software package was used to estimate the population parameters. The mean number of complete and equivalent generations is relatively low (1.72 ; 2.71). The average inbreeding coefficient is relatively high (5.13%), while the mean average relatedness coefficient is of concern in terms of population sustainability (14.56%). The effective number of founders and ancestors of the reference population is low (9, 8) and their ratio (1.12) confirms the bottleneck that the population went through three decades ago. The average generation interval is 6.34 years and ranges from 5.84 (father - son) to 6.76 years (mother - son). The mean age of parents at the birth of offspring was 6.92 years. The population indicators calculated on the basis of pedigree records indicate the vulnerability of the Slavonian-Syrmian Podolian cattle. It is necessary to reduce the level of inbreeding, preserve existing lines and partially refresh the genetic potential of the breed. |
