Abstract: In modern dairy farming, it is customary to first use the value of milk yield for 305 days of lactation when calculating the economic efficiency of breeds. We have considered the productive potential of the breed according to the set of productive characteristics throughout the life of the cow. As of 2009, three breeds of cattle were bred in plants in the North-Western Federal district, five breeds were in reproducers, and seven breeds were in farms of all categories. A slight change in the number of breeds was noted in 2018. There is an increase in productivity indicators for all the considered breeds. It is shown that breeds that in 2009 had the best indicator for the aggregate of productive characteristics, in 2018 began to give way to other breeds of livestock. Based on the analysis, we can see the dependence of the number of calves and the safety of the herd on the amount of milk received per lactation. The article uses the method of complex assessment of economically useful animals using all data on the last completed lactation of cows. The analysis of productivity parameters for the entire life of the animal was performed. The paper considers native and imported breeds of cattle.
