The superiority of the new genotype over peers of fine-wool breed is: for the production of lamb in live weight of 74–83% to (40–45 kg per initial sheep, 71–74,5 kg per ewe), slaughter weight 20% and profitability 104–117 absolute percentages (up to +165, +178%) due to an increase in multiple pregnancy by 58,1–62,4% (1,85–1,90 lambs from one ewe).
