Abstract

3369 rams of 28 breeds from 233 farms were classified for registration of breeding ram between years 2005-2010. The exterior in the majority of sheep breeds was assessed using a linear type traits system, followed by granting summary class for appea­rance. The range of categories of body scoring (1-5) was little used. Most of traits are most often described by the mean value, in traits musculature and body frame is a high percentage of assessment by a rate 5. There is a tendency to classify animals by the highest rate in summary class for appearance, 45,4 % of rams were registered in the class Elite Record. Low variability of assessments and preference of some class precludes using data for estimating BV.
