As shown by the research results, the use of "Bioseven" contributed to obtaining at the age of 2.5 months the average daily gain of lambs in the experimental group of 217.1±10.55 g, which is 17.1% higher than that of analogues. After weaning at 2.5 months of age, the animals were kept according to the feeding technology. Control slaughter at 5.0 months of age showed that the control and experimental groups lambs had: slaughter weight - 14.08±0.77 and 16.05 ± 0.46 kg slaughter yield - 45.88±0.73 and 47,52±1.17%. Lambing of the Ascanian Fine-Fleeced breed ewes (n=49), which were fertilized by the Ost-Friesian rams, was carried out. At 90 days of age, lambs were weaned from ewes. In crossbred (n=26) and Fine-Fleeced (n=14) lambs, the average daily gain in 90 days was 266.7±9.13 g and 240.0±6.52 g, respectively. After weaning, the lambs were fed intensively. The average daily gain of lambs in the experimental group for the period from 3.0 months to 5.0 months of age was 180±8.32 g, which is 24.1% higher than the performance of analogs from the control group (145.0±6.14 g) , at P> 0.99. Control slaughter at 5.0 months age showed that the lambs of the control and experimental groups had: slaughter weight - 14.67±0.85 and 15.94±0.54 kg; slaughter yield - 45.50±1.12 and 46.92±0.51%. The average daily gain of lambs in the experimental group for the period from 5.0 months to 6.5 months of age was 177±4.96 g, which is 10.6% higher than these indicators of analogues. It was found that the content of intramuscular fat in the control lambs was 2.34%, while in the experimental rams it was 2.91%, or 24.4% higher. Conversion of protein and energy of feed into food protein and energy of carcasses was 5.79 and 5.12 in the control lambs, while in the experimental ones it was 7.22 and 5.20.
