However, in the conditions of industrial technology, this method does not ensure the maintenance of the cleanliness of the broodstock and the cultivation of repair of sheep of multiple breeds, since in this case, the introduction of repair young stock from other farms is required to preserve the broodstock. In this case, there is a risk of introducing 20 infectious, invasive and other diseases.

To prevent these phenomena, it is necessary to carry out a closed reproduction of broodstock. 25 '

The purpose of the Invention is the preservation of the purity of the production of broodstock by self-repair.

This goal is achieved by the fact that queens with multiple breeds of successive rams do not reduce fertility, increasing the production of mutton in live weight by 6001,000 kg (13-21%) per 100 queens, and breeding nifepct * * by 35-48 kg. those. two times, and reduces feed costs by 17%.

The method can be used by collective farms and state farms of the country, underestimated by the sold breeding of Romanovsk sheep for a significant increase in the production of mutton and fleece.
