The article presents materials on the selection and genetic indicators of black-and-white cattle. The amount of repeatability allows for selection by productive qualities already in the first lactation. There was a significant negative moderate relationship between the mass fraction of fat and milk yield for 305 days of lactation (- 0.308; Р>0,999). There is a tendency of negative weak dependence between the milk yield and the mass fraction of protein, namely, the increase in milk yield is accompanied by a slight decrease in protein content.

The research has been carried out to establish the duration of productive use of breeding stock in the breeding farms of the Omsk region. As far as the productive use duration, the cows kept in free stall housing are found to have a significant advantage compared to the tied cows, the difference being 177 days or 17.2 %. A negative correlation has been established between the abundance of milk and the duration of productive use of cows in tied herds.

The results of research in milk productivity of lactating cows using the feed concentrate “Urga”, products of the EM series (LLC “EM-cooperation”) were analyzed. The received the feed concentrate “Urga” animals had higher monthly milk yield, the amount of milk produced in terms of base fat and protein, higher level of realization of productive capacity, which pointes out the feasibility in developing a feeding program and increasing the efficiency of milk production.

Studies having been carried out on animals of Ayrshire breed show that indexes of food, motion and total activity selection can be successfully used as selection signs. Selection of cows on ethological individuality is accompanied by an increase of their milk production. Animals with increased food activity, compared to cows with a low one, have got the rise of milk yield per lactation by 686 kg. Ultra-active cows should be mentioned particularly, productivity of them opposite to infrapassive ones increases by 49%.
