Sažetak
Heritability of morphological properties of Lipizzaner horses in Croatia was estimated by various methods. Heritability for withers height, obtained by the method of interclass correlation, was somewhat higher (h2=0.32) compared to the method of regression and REML method (h2=0.29 and 0.26, respectively). The same was estimated for hearth girth and cannon bone circumference. At the three investigated properties the variance within sires was higher than the variance betwen sires, which indicates higher genetic variability of the offsprings within sires. Heritability value obtained by ML method for withers height of mares exceeds the heritability value by REML method for 0.01. As for hearth girth, the heritability value is the same, whereas cannon bone circumference of mares is for 0.02 higher than the values by REML method. Average heritability for body measurements at foaling and at six months of age increased with the increase of foaling number. For the first and second foaling, heritability was h2=0.27, and for the first to the fifth foaling it was h2=0.34. The same trend was found for both heritability height for hearth girth and cannon bone circumference at foaling and at six months of age. This points out slightly higher influence of genetic factors upon variability of the analysed morphological properties in later foalings.
