УДК 636.2.034
Abstract: 

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.
