Abstract: A scientific experiment was carried out in Experimental station on agriculture - Sredetz with 8 lactating sows from East Balkan breed, to study the effect of adding wheat Distillered Dried Grain with Solubles (wDDGS). Animals were distributed in 2 groups by 4. Sows of the control group received compound feed and those of the experimental - 70% of this feed and 30% wDDGS. Sows were fed with traditional natural diet – on pasture and feeding of compound feed 2 kg per animal per day. Replacement of 30% of the traditional feed with wDDGS had a strong positive effect on final live weight of lactating sows from East Balkan breed - at weaning of piglets. The decrease in weight of pigs of the experimental group was 0.174 kg/sow/day, statistically not significant, was more than half (51.72%) of those of the control group – 0.337 kg/sow/day. Initial live weight of lactating sows has been had a weak, positive and statistically significant impact on their weight at weaning of piglets (P = 0.023).
