Abstract: The objective of this study was to evaluate the effect of supplementation of hidrolyzed poultry feather and S, Cl as the essential macro mineral and I, Co, Se as essential rare mineral in plantation by-product based ration to feed corvension ratio and income over feed cost. The experiment was designed in a randomized complete block design with 2x4 factorial arrangement. The first factor was sheep breed consisted of 2 levels, b1 (sumatra thin tail lamb) and b2 (sunge putih crossbred). The second factor was supplementation consisted of 4 levels, s1 = basal ration (control) contains 14% crude protein (CP) and 70% total digestible nutrient (TDN). s2= s1 + hidrolyzed 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 heads b1 and 12 heads b2 were used in the experiment. Lambs were divided into 3 group based on the initial body weight. Initial body weight of lamb was 23,90 ± 2,60 kg. The result of research showed that hidrolyzed poultry feather and S, Cl as well as I, Co, Se supplementation decreased feed conversion ratio and increase the income over feed cost. The value of feed conversion ratio at b1 was higher (P
