Abstract

The article deals with the data on test results of efficient use of four suggested estimation methods by different authors of exterior–constitutional types of bulls on the Polissya meat breed:

– visual assessment of the animal type of structure on  a 100–point scale,  according to the «Instructions for appraisal of meat breeds cattle»:

– evaluation of the body structure on the model deviations by the formula of  M.M. Kolesnyk (1960), A.M. Uhnivenko (2010);

– eirisomia index by the formula of M. Zamyatina (2005);

– mass and metric coefficient by the formula of D. Vinnychuk et al (2005).

Thanks to carried out investigations it have been established, that the most appropriate is the  use of mass and metric factor by D. Vinnychuk. However given the fact that the use of other methods, in particular by model variations of M. Kolesnyk, A. Uhnivenko, the correlation connection was high, and the difference is statistically significant, in our opinion can be used in scientific research, both methods of evaluating structure of  the animals body structure.
