The purpose of the work is to improve the methods for evaluating the milk productivity of the owls of the Novo-Aleksandrovsky heavyweight breed. Methods of research - the tasks set in the work were solved experimentally using analytical (analysis of literature sources, generalization of research results), zootechnical (fit, measurements, indexes of body structure); biochemical (chemical composition of milk, blood), statistical (biometric processing and estimation of the probability of the obtained results), economic (determination of the economic efficiency of milk production) methods of research. The milk productivity of the mare of the Novo-Aleksandrovsky heavy-breed breed has been investigated, according to which methods for evaluating the milk production of mare are improved. The method of determination of doses according to the measure of udder is offered. The mathematical dependence for determining the milk yield of the mares for 150 days has been developed, taking into account the length of the service-period and the age of the animal. A formula has been developed and proposed for determining the milk yield of mare for the size of the horses.
