A note on the nutritive value of roasted velvet bean (<i>Mucuna pruriens</i>) in broiler diets

Abstract

The nutritive value of roasted Mucuna pruriens var. utilis (mucuna or velvet bean) was investigated in a four-week study using 336 mixed-sex three-week old broiler chickens. The birds were randomly allocated to four dietary treatments. Fifty, 100 or 150 g of mucuna beans, roasted in metal bowls over a wood-fired stove until they turned light brown was included into nutritionally balanced diets. Control diet did not contain mucuna beans. Feed and water were supplied ad libitum. Performance criteria studied included feed intake, growth rate, feed conversion ratio, carcass parameters and mortality.Roasted mucuna beans at the levels of 50 and 100 g kg" 1 significantly (P<0.05) improved the growth and feed utilization of broilers. At 150 g kg" 1 diet, however, mucuna beans depressed weight gains and feed utilization.

Volatile Composition, Toxicity, Analgesic, and Anti-Inflammatory Activities of Mucuna pruriens

“…19 The combination of the seed powder with animal feed improves the growth and feed utilization of broilers due to the high content of protein and crude fiber. 20 Volatile oils of the leaves of Mucuna sloanei Fawc & Rendle analyzed in Nigeria contained high amounts of α-terpineol (18.1%), nerol (17.5%), α-campholenol (13.1%), and hexadecanoic acid (13.4%). In comparison, the stem oil is of nonterpenoid compounds such as hexadecanoic acid (25.9%) and ( Z , Z )-9,12-octadecanoic acid (16.7%).…”
