    ABSTRACT : In a completely randomized design, the effect of replacing DORB with sheanut cake at 0 (T-1), 50 (T-2), 75 (T-3) and 100% (T-4) in growers (15-35 kg body weight) and finishers (35-70 kg body weight) on the growth performance , nutrient utilization, serum metabolite profile and carcass characteristics were studied using 24 crossbred (LWY x Desi) pigs. During grower phase the number of days taken (56, 71.6, 91.8 and 92), average daily gain (362, 282, 224 and 219) and feed/kg gain (3.31, 4.11, 4.85 and 5.04) decreased significantly (P<0.01) as the level of inclusion of SNC increased in T-1 to T-4 fed rations, respectively. The digestibility of DM and nitrogen retention expressed as g/d, as % of intake or as % of absorbed decreased (P<0.01) as the level of inclusion of SNC in the rations increased. The cost of the ration/kg weight gain was significantly (P<0.01) lower in T-1 (Rs. 55.22) than in T-2 (65.75), T-3 (76.28) or T-4 (76.82) fed pigs. During the finisher phase also increase in number of days taken to reach target weight, decrease in ADG (g), and increased in feed/kg gain was observed and the values were 93, 95, 105 and 156 (number of days), 395, 384, 334 and 223 (ADG) and 3.60, 4.99, 6.15 and 7.25 (feed/kg gain) in pigs fed T-1 to T-4, respectively and the differences among the treatments were significant. The digestibility of DM, OM and CP decreased while the N retention expressed as g/d, % of intake or % of absorbed was also decreased (P<0.01) in pigs fed diets containing sheanut cake (T-2 to T-4) than those fed T-1. The cost of feed/kg gain (Rs.) was 60.07, 77.41, 92.35 and 103.94 in pigs fed T-1 to T-4, respectively. For the overall growth study, a similar trend of increase in number of days taken to target weight (149,167, 197 and 248), decrease in ADG (379.6, 331.1, 282.5 and 220.4) and increase in feed/kg gain (3.50,4.67,5.67 and 6.45) was observed in pigs fed T-1 to T-4, respectively. The cost of feed/kg gain (Rs.) was significantly (P<0.01) increased from 57.81 (T-1) to 73.15 (T-2), 86.47 (T-3) and 94.11 (T-4).
