This study aims to identify phenotypical traits of the Hungarian Grey (HG) and two more podolic breed (Maremmana, Anatolian Grey) with the Video Aided Measurement (VAM) method. The sample has been gathered from 1090 Hungarian Grey out of five herd and 26, and 30 from the Maremmana and Anatolian Grey. The measurements have been done by taking relevant pictures from videos recorded through the optometric VAM method. As the animal stands still in pictures, the measurements obtained via this method are safer, practical and reliable. The standard deviations and the average body size of Hungarian Grey cattle examined by this method were found to be: height at withers 133,0 cm (sd:5,7); height of back 131,5 cm (sd:5,7); rump height 133,7 cm (sd:6,1) trunk length 157,6 cm (sd:9,7); chest depth 76,9 cm (sd:4,3); body length 152,6 cm (sd:10,6); width of chest 45,5 cm (sd:4,3). The discriminant function analysis of intra-(Hungarian) and inter-breed dataset showed that there were statistically significant phenotypical differences among the herd. Based on the results, the VAM method can be a potential tool for conservation herds, primarily for obtaining the data of phenotypical aspects. New approaches like geometric morphometry can also be used for gaining phenotype data.
