Abstract


The aim of the study was to analyse type traits in 330 Cika sires. Scoring system of Cika cattle includes measured, individual scored and composite scored traits. Individual scored traits are divided into two groups, autochthonousness and form. Three composite traits are autochthonousness, muscularity and form. Fixed part of the model was analysed by GLM procedure in SAS software package, which included the effect of the year and animal age on the scoring day as linear regression. On average, 14.6 months old sires were 117.1 cm high at withers. Immediately, at the end of the scoring procedure all sires were classified into Cika, Semi-Cika and Pinzgauer type, based on the height at withers and individual scored traits from the autochthonous group. This method of classification does not take into account the environmental effects. We found significant effects of the year of scoring and animal age on type traits and therefore on the classification into the type. Sires classification should be carried out after the type traits data evaluation and after the exclusion of environmental effects.
