Sažetak

Breeding and selection of the Lipizzaner horses are based on estimating of the body conformations, which should correspond to the desirable type of the breed in question. Some information about the stallion s offspring can reduce the testing time and speed up the decision-making concerning the selection. The purpose of this study was to estimate the breeding values of the Lipizzaner stallions for height at whiters and chest girth under the breeding conditions in the Centre for horse breeding and selection in Đakovo, Croatia. The data were obtained on 305 foals sired by 12 stallions. The genetic and the phenotypic variances were estimated by means of the restricted maximum likelihood (REML procedure). The heritability for height at whiters and chest girth was 0.26 and 0.25 respectively. The breeding values for body measurements were estimated by BLUP method. The model included the year of birth, the foaling number and the sex as fixed effects, and sires as random effects. The estimates concerning breeding values ranged from 0,611 to -0.264 form height at whiters and from 0.215 to -0.232 for the chest girth. This paper also discusses the rank of stallions concerning the estimation of the breeding values and possibility to use such issues of information in breeding and selection.
