A total of 64 piglets, castrated male and female, of commercial lineage, weaned at 43 days of age and with average live weight of 10.73 ± 1.85kg, were used with the objective of evaluating the effect of the inclusion of different levels of rice bran (RB) in ration up to 67 days of age on productive performance, feeding forms and economic viability. The experimental design was completely randomized in a 4 x 2 factorial arrangement, four levels of inclusion of RB (0, 10, 20 and 30%) and two feeding forms (dry ration and wet ration), with four replicates per treatment, and the experimental unit consisted of two animals. The daily feed intake (DFI), daily weight gain (DWG) and feed conversion (FC) did not differ significantly (P> 0.05) for the different levels of inclusion of RB or the feeding forms. The economic analysis showed that the inclusion of 30% of RB had the best economic response. It was concluded that the supply of rice bran was viable until the level of 30% of inclusion in diets of piglets in the period from 43 to 67 days of initial phase, regardless of the feeding forms.KEYWORDS: Alternative feedstuff; bioeconomic analysis; swine; zootechnical performance.
