This study aimed to determine the influence of fodder type administered in two consecutive years (2022 and 2023) to sheep mothers in the lactating period on the growth performances of suckling lambs, to improve growth rate up to weaning. The lambs from Ţigaie breed - rusty variety (209 lambs born in 2022 and 219 lambs born in 2023) were used in the experiment from lambing up to weaning. The fodder administered to the ewes-mothers had provided a nutritional value of 198 g DP and 12.75 MJ NEM (net energy milk) in 2022, the fodder consisting of concentrates (grain corn 50%; grain barley 50%) and hill hay, while the fodder administered in 2023 is consisting of alfalfa semi-silage, hill hay and concentrates (50% grain corn; 50% grain barley) and had provided 198 g DP and 14.75 MJ NEM. The alfalfa semi-silage had significantly influenced (p<0.001) the growth performances of lambs in 2023 compared to those born in 2022 regarding weaning weight (19.98 kg vs. 16.82 kg), total weight gain (15.71 kg vs 12.84 kg) and average daily gain (224.44 g vs. 183.49 g).
