Ecosistemas y recur. agropecuarios [online]. 2019, vol.6, n.16, pp.121-127.  Epub 01-Out-2019. ISSN 2007-901X.  https://doi.org/10.19136/era.a6n16.1815.

The effects of Mucuna pruriens (MP) seeds soaked in water (WMP), acetic acid (AAMP) or calcium hydroxide (CHMP) solution + boiling on both its L-Dopa content and the productive performance of broiler chickens were evaluated. The experiment included a control without MP (C). The CHMP treatment reduced 71% of L-Dopa in comparison to AAMP (53%) or WMP (41%). In the starter phase, the AAMP group had the lowest live weight gain (p < 0.05) and the highest feed conversion ratio than C (p < 0.05). Broilers fed with CHMP and the C did not differ (p > 0.05). In the finisher phase, there was not statistical difference in any of the variables evaluated (p > 0.05). Differences were not observed in carcass yield (p > 0.05), but the broilers fed with WMP or AAMP had a heavier liver than birds on C group (p < 0.05). Results showed that 25% of CHMP can be used as ingredient in broiler diets.
