Abstract: The study was performed with ewes of the Bulgarian dairy synthetic population from herd of Agricultural Institute - Stara Zagora in 2008. Ewes - 26 number on first lactation were kept under the same conditions were lambing within 15 days and fed during this period with the same rations. The aim of the study was to trace the relationship of body condition score and production traits live weight, milk yield, average daily milk yield and prolificacy and relationship of these indicators and body condition score with some exterior measurements. Based on interpretation of information were made the following conclusions: Significant dependence was determined between live weight with body condition score - 0.64. The relationship between body size and hip width is highly significant, 0.78 and 0.73 respectively. Our results on the relationship between individual measurements and body condition score ranged from
low to moderate - from 0.14 to 0.53 and are not reliable. Scope of the chest, hip width and chest depth are exterior measurements, most of which highly dependent on body condition score and body size.
