Sažetak
Croatian Posavina horse is one of the three autochthonous horse breeds in Croatia. During the past twenty-five years, his program of protection has been implemented. After inventarisation and stopping the decline of the population, the breeding organisation formed sire lines to efficiently improve the breeding program. The Croatian Posavina horse has defined 30 sire lines. It was necessary to determine the conformation of the sire lines, therefore 92 active studs were included in research and through it collaboration with the breeding association was achieved. The determined values of the withers height, chest circumference and the cannon bone circumference were 141.98 ± 4.34 cm, 194.17 ± 8.47 cm, and 22.18 ± 0.95 cm, respectively. According to the previous study, stallions in this research have smaller values for withers height (-1.55 cm ; p < 0.05) and chest circumference (-5.82 cm) while the cannon bone circumference was wider (+0.28 cm). Comparing the dispersion parameters revealed that the phenotypic variation of the examined traits has decreased, which can serve as a good indicator of the consolidation of exterior traits. Monitoring of the breed through phenotypic level and planned mating, should be continued in order to provide its viability. In addition, stronger efforts should be made in promotion and economic affirmation of the breed, especially if long-term sustainability is expected. Good breeding practice encompass regular monitoring of the population trends by analysing phenotype variability within Croatian Posavina Horse populations. Furthermore, balance between sire and dam lines will help in preserving genetic diversity as one of the important component of conservation program.
