An experiment was carried out with two objectives: (a) To determine the optimum amount of Stylo 184 as replacement for rice bran in diets for indigenous pigs, (b) To study the effects of Stylo 184 on intake and growth performance of indigenous pigs. Sixteen indigenous pigs of 12±1.63 kg and 3 months of age from the upland area were used in the experiment. The experimental design was a completely randomized design (CRD) with 4 replications. The dietary treatments were: T1: 50% maize + 50% rice bran + 0% Stylo 184; T2: 50% maize + 40% rice bran + 10% Stylo 184 fed separately; T3: 50% maize + 30% rice bran + 20% Stylo 184 fed separately, T4: 50% maize + 20% rice bran + 30% Stylo 184 fed separately. The results revealed that total DM intakes were 942g, 1224g, 1221g and 1309g for T1, T2, T3 and T4 treatments, respectively, while DM intakes of Stylo 184 in total DM intake were 49.2g (4.1% of diet), 76.5g (6.3% of diet) and 82.7g (6.4% of diet) for T2, T3 and T4 treatments, respectively. The average daily gains (ADG) were 154g, 221g, 245g and 320g for T1, T2, T3 and T4 treatments, respectively. ADG was significantly higher (p<0.01) for the T4 treatment than for the other treatments. FCR were 6.25, 5.50, 5.00 and 4.00 kg feed/kg gain for the T1, T2, T3 and T4 treatments, respectively. Based on the results of this research it was concluded that indigenous pigs with live weight 10-40 kg can consume Stylo 184 as unconventional feed at up to 6.4% of the diet DM without any negative effects on health and growth performance and with a higher profit for the farmers.
