Abstract: The aim of the study was to estimate some body measurements in ewes from Synthetic population Bulgarian milk (SPBM) and Blackhead Pleven (BP) breeds and verification of the statistical hypotheses for origin of these breeds to the same population in terms of parameters examined. The study was conducted in
Research Institute for Land Reclamation and Agricultural Mechanization - Sofia, Institute of Animal Science - Kostinbrod and Institute of Forage Crops - Pleven. There were made a total of 270 body measurements - for SPBM - 150 and for BP - 120. For processing the data was used the software product Statgraphics Centurion XV.
The estimates of numerical characteristics of the body measurements were obtained. The exterior profile of the studied flocks showed fluctuation of the body measurement of the comparative BP breed in relation to basic SPBM in interval from -21.40% to + 35.26 %. Between the compared flocks were found significant
differences (with except of the parameters Brisket height and Body width) and so they can not belong to the same population. In determing the type and parameters of the technology constructions of the milking installations for group ewes milking, the results for Brisket height and Body width of either of the two breeds could be used. For the rest parameters should be taken into account the results of sampling for both breeds.
