Resumo: It was 32 piglets castrated males of commercial lineage, with 70 days old and with mean weight of 27,53 kg, with objective to evaluate the effect of the inclusion of different levels of cashew nut meal (CNM) and feeds forms on the performance zootecnic of swines in the phases of growth (from 70 to 104 days and weight from 27,53 to 61,4 kg) e termination (from 104 to 137 days and weight from 61,4 to 93,7 kg), how so your economic viability. The experiment design used was randomized blocks with scheme factorial 4 X 2, four levels of inclusion of CNM (0; 6; 12 e 18%) and two feed forms (humid and dry diets) with four replications to treatment and one animal to part. The criterion used for block formation was the initial weight of animals. In the phase of growth and during the total period, the daily mean weight gain (DMWG), daily mean feed intake (DMFI) and the feed conversion (FC) weren´t affected (P > 0,05) by inclusion of different levels of cashew nut meal (CNM) and humid and dry diets. In the phase of termination, the daily mean weight gain (DMWG) and the feed conversion (FC) didn´t exhibited different significant, but, there was decrescent linear effect (Y = 3.372,6 – 24,56x) with R2 = 0,82 to the daily mean feed intake (DMFI) of swines while increased the levels of CNM. There was significant different in the interation between the inclusion levels of CNM and humid diets, exhibiting crescent linear effect (Y = 938,65 + 6,9x) with R2 = 0,79 and (Y = 980,75 + 3,79x) with R2 = 0,73 to the daily mean weight gain (DMWG) in the phase of growth and during the total period, respectivement, and to the dry diets, decrescent linear effect (Y = 3.470 - 38,33x) with R2 = 0,81, to the daily mean feed intake (DMFI) in the phase of termination. Concluded that the utilization of cashew nut meal until the level of 18% in the feeds is viable technicament for swines in the phases of growh and termination, and that the inclusion levels of CNM of 12% obtained the best bioeconomic response.
