The objectives of our study were to evaluate chemical composition and the effects of dried distillers grains with solubles - DDGS on feed intake, growth and gain efficiency of fattening Synthetic Bulgarian Dairy Population lambs. Thirty-two lambs - 16.69±2.53 kg initial body weight and 59 days of age were separated by weight and sex into one of 2 pens and assigned to treatments n=2. Diets were formulated to meet crude protein, energy, calcium and phosphorus requirements. Treatments were isonitrogenous, isocaloric and with balanced calcium/phosphorus ratio. The basal diet consisted of roughage - meadow hay, triticale, corn grains and a trace mineral - vitamin mix. Protein forage was 37.58% DDGS vs. 26.33% sunflower meal on a diet basis - 16 lambs.diet-1. Feed intake was monitored daily. Body weight was monitored every 2 weeks. Feed intake, average daily gain and gain efficiency were determined following 82-day long trial. Final body weight and average daily gain were significantly affected by DDGS - p0.001 treatments. Total DMI was greater in lambs fed DDGS diet as compared with lambs fed sunflower meal diet. Results indicated that DDGS is a viable feedstuff for fattening lambs without any compromise to performance.
