There are given the results of the selection, the assessment of future mothers of bulls of the Simmental breed. The materials for the research were cows of the first, second and third lactation of the Simmental breed of the herd of the breeding farm Society of limited liability “Strapit”. The studies were carried out according to the scheme developed by us according to the following parameters: origin and genetic examination; constitution and exterior, marker alleles; productivity; breeding value; genetic evaluation methods. Milk yields for 305 days of lactation on average for the population of Simmental cows amounted to 6017 kg of milk, which is by 455 kg of milk more than the average for the first lactation, the difference is significant (P<0.005). Alleles B2I1Q, Iʹ, IʹQʹ are markers for the Simmental breed. There were selected 4 cows as candidates for mothers of future bulls, whose productivity in terms of the highest lactation varied within 7029-8003 kg of milk.
