Methods and methods of measuring cattle in agriculture

Overview of methods for measuring the mass of cattle in agro-industrial complexes. Parametric methods of mass measurement were considered, which in turn are based on animal measurements, walk-through and free-standing scales, as well as built-in scales in a milking robot. Among the new measurement methods, optoelectronic 2D and 3D were considered, based on obtaining a two-dimensional and three-dimensional model of an animal, which are further processed and parameters are derived by which it is already possible to judge the mass of the animal. During the analysis, the advantages and disadvantages of the considered measurement methods were found. Methods of remote mass measurement and the possibility of their application on farms are described. New methods of measuring mass do not cause stress in animals, which has a beneficial effect on the productivity and health of the animal.
