The experiment was carried out at Universidade Estadual de Londrina, Paraná, with the objective of evaluating the effects of the utilization of raw pigeon pea ground (RPPG) variety IAPAR 43-Aratã, in the ration, on the productive indirect index of broilers at period 1 (1-28 days) and its influence on the period 2(29-45 days) and also on the total period (TP= 1-45 days). 270 chicks of Arbor Acres line were used, located in metalic batteries, consisting of 6 treatments repeated 3 times in randomized blocks, each experimental unit consisting of 15 chicks. The levels of RPPG tested were 0, 10, 20, 30, 40 and 50% in rations. All the rations were formulated to contain 20.1% of crude protein (CP) and 2910 kcal of metabolizable energy (ME)/kg. In the period 2 (P2) all the chicks of the treatments of period 1 received only commercial ration containing 19% of CP. The studied characteristics were, mean body weight (MBW), viability (V), daily mean weight gain (DMWG), production per unit of area (PUA) and productive efficiency index (PEI). At P1, quadratics effects were observed (P<0.05) of the treatments on the MBW (Y = 892.198 + 3.90441X-0.119305X2; R2 = 0.80); on the DMWG (Y = 30.2807 + 0.137373X - 0.00423176X2; R2=0.80); on the PUA (Y - 12.5828 + 0.0555773X - 0.00192518X2; R2 = 0.85); and on the PEI (Y = 155.727 + 1.05705X - 0.0386427X2; R2 = 0,84). On the TP the effect was linear (P<0.05) on the PUA (Y = 28.5481 -0.0482253X; R2=0.60) and on the PEI (Y = 220.470 - 0.529862X; R2=0.46).
