The variability of morphological traits of sheep udders was studied in the Polish Lowland, Polish Merino and Polish Highland sheep, which are bred for different purposes. Beside differences among breeds, intrabreed differences were found as regards the analyzed traits. The ewes of the breeds studied differed as regards udders shape and frequency of such anomalies as asymmetry of udder lobes or extra teats. The genetic parameters (heritability, repeatability and correlation) evaluated had moderate to high values, depending on the trait. This indicates a possibility of selection for improvement of udder health and shape and for increased productivity.
