Methods of research - scientific and industrial research, laboratory research, the settlement and the comparative method, methods of mathematical statistics. The results of the research - іmproving of genetic peculiarities of fine-wool sheeps of Zakarpatsky type of Precos, which on the reproductive capacity (fecundity on 8,5-14,3%, fertilizing - 4,0-6,3% of juvenile mortality -1,2-2,0%) and wool productivity by 9,5% higher than the pure-bred sheep analogues of Zakarpatsky type of Precos breed, allowing to receive 31 UAH per head additional revenue from the sale of meat and wool. Crossed young in the suckling period on average gain in 14,1-15,6%, in the period from weaning to 8 months of age at 9,0-10,5% higher than pure-bred peers. The use of lead-crossing during the years of research has provided a significant increase in ewes with long hair 8,5 cm and the output fiber net 52% reduction in the number of animals with a yellow and an increase in animals with a light creamy white and yolk.
