Study of the influence of the main factors on the productivity of cows

The purpose of the study is to develop methods and techniques for optimizing the technological parameters of particularly important factors affecting the state of the fertility of animals, providing an increase in the productive longevity of cows, the volume of milk production and reducing losses at minimum production costs. The solution of the problems ensuring the achievement of the research goal was carried out by theoretical methods (information review and patent search; identification of regularities, dependencies and factors that determine the effectiveness of improving the reproductive performance of cows) and experimental studies (obtaining and primary processing of initial information from the materials of the annual periodic reporting of enterprises; the choice of a mathematical model of the process). On the basis of the results of research measures to optimize the fertility of dairy cows, the state of fertility, including the factor ‘service’ (motivation of dairy cattle without investing additional funds).
