Ninety-six sexed chicks aged 21-days old with an initial live weight of 720 ± 80 g were used. Four diets were used, a control without MP (C) and three diets including 25 % MP: a) soaked MP in tap water + cooking (WMP); b) soaked MP in acetic acid solution + cooking (AAMP); c) soaked MP in calcium hydroxide solution + cooking (CHMP). The alkaline treatment reduced 71 % of L-Dopa in comparison to acid or water treatment (53 % and 41 % respectively). In the starter phase, the acid group had the lowest live weight gain (p&lt;0.05) and highest feed conversion ratio when compared to control (p&lt;0.05). Productive performance of birds fed with CHMP and C group was similar (p&gt;0.05). In the finisher phase, there was not statistical difference in feed intake, live weight gain and feed conversion ratio among treatments (p&gt;0.05). No differences were observed in carcass yield (p&gt;0.05), but, the birds fed MP or AAMP had a heavier liver than birds on C group (p&lt;0.05). Results shown that 25 % of CHMP can be used as feedstuff for broiler chickens without negative effects in their productive performance.<strong></strong></p><p> </p><p><em>Keywords</em>: Velvet bean, L-Dopa, Poultry, weight gain.</p> ER -
