Abstract

The use of a rotational scheme for sheep selection in purebred breeding in a closed population ensured the maintenance of a high level of productivity of long-wooled sheep and their advantage in live weight by 24,0–27,0%, fertility by 20,8%, and maturation from 15,1 to 18,3%, wool productivity – up to 36%, compared with the requirements for the breed, as well as flock replacement due to its own reproduction without expensive import of paternal breeds.
