The experiment wasdesigned in a randomized complete block design with 2 x 4 factorial arrangement. The first factor wassheep breed consisted of 2 levels, b1 (sumatra thin tail lamb) and b2 (Sunge Putih crossbred). The secondfactor was supplementation consisted of 4 levels, S1 = basal ration (control) containing 14% crude protein(CP) and 70% total digestible nutrient (TDN). S2 = S1 + hydrolyzed poultry feather 3%. S3 = S2 + 0.12%Cl + 0.17% S and S4 = S3 + 0.40 ppm I + 0.15 ppm Co + 0.15 ppm Se. Twenty four heads lamb, 12 headsb1 and 12 heads b2 were used in the experiment. Lambs were divided into 3 group based on the initialbody weight. Initial body weight of lamb was 23.90 ± 2.60 kg. The results showed that hydrolyzed poultryfeather and S, Cl as well as I, Co, Se supplementation did not increase the utilization and biological valueof protein, but increased ration efficiency. The value of ration efficiency at b2 was higher (P
