This article provides an analysis of the exterior of cows by physique indices. The purpose of this work is a comparative study of the exterior of cows of black-and-white, Simmental breeds and their crossbreeds. When comparing the physique indices, it was found that the culled cows of Simmental breed and crossbreeds after fattening had the highest indices: elongation, plumpness, chest, pelvic and massiveness. The results show that cross-breed cows (black-and-speckled x Simmental) are the largest among the breeds. The smallest cows of these represented breeds are black-and-speckled.
