The purpose of this study was to examine the impacts of dried white mulberry pomace on yield performance in lambs. study used 42 weaned Merino lambs, both male and female, at 3 months of age. The experiment was conducted in 3 groups: control, MP150 (150 grams of mulberry pomace), and MP300 (300 grams of mulberry pomace), each containing 7 male and 7 female lambs. The lambs were subjected to a 14-day phase of adaption and 90-day fattening period feeding, and performance parameters were examined in 15-day intervals. Blood samples were collected from the lambs during the experiment's beginning, middle, and end of analyze metabolic profile parameters. The average increase in live weight in the study was determined as 60,9% in the MP150 group, 58,7% in the MP300 group, and 46.7% in the control group. The daily average live weight gains were found to be 0,20 kg/day in the MP150 group, 0,18 kg/day in the MP300 group, and 0,16 kg/day in the control group, although there was no statistically significant difference between the groups (p>0,05). There was no noticeable difference detected between groups in dry matter consumption (p>0,05). Changes were observed in metabolic profile parameters, but there were no discernible variations in terms of group and group × time interactions (p>0,05). Consequently, it may be claimed that mulberry pomace has positive effects on daily and average live weight gains, feed consumption, and feed efficiency ratios of lambs. In line with the effects of mulberry pomace, it shows that it has alternative feed source potential. This study, in which mulberry pomace is examined in many aspects, is thought to guide future research.
