Findings: • During the winter-spring lambing season, when ewes with offspring were kept in groups of 15 and 30 heads per section, no significant differences were observed in lamb survival from birth to weaning. However, lambs in the experimental group with 15 ewes and offspring showed significantly higher average daily gains and live weight at weaning. • Ewes in the experimental group maintained better body condition during the suckling period and had statistically significantly higher live weight (P<0.05) after weaning compared to ewes in the control group. • Under stall fattening, ram lambs had 30% higher average daily gains (199 g vs. 153 g) compared to grazing on natural pastures. Ram lambs reached a live weight of 40 kg 21 days earlier under stall fattening than under pasture grazing. • Feeding biologically active additives—probiotic KluActive and postbiotic Nutrilys KM in the diet of suckling ewes contributed to better preservation of body condition until the end of the suckling period and positively influenced their milk yield. • Feeding lambs with postbiotic Nutrilys KM from 20 days of age until weaning ensured a statistically significant increase in growth intensity and live weight at weaning compared to peers in the control group. • Feeding ram lambs of the current year’s birth with probiotic KluActive and postbiotic Nutrilys KM under stall fattening had a positive effect on their growth intensity and slaughter traits.
