Evaluation of nutrient and anti-nutrient content of both raw and processed velvet bean seed (Mucuna sloanei

Abstract

The nutrient and anti-nutrient content of raw, boiled, and boiled with potassium sesquioxide(akanwu) Mucuna sloanei seed meal(MSSM) were investigated. A total of 120 day old broiler chickens were used. There were 4 treatments each replicated into 3 with 10 birds per replicate in a completely randomized design (CRD). Four treatment diets were formulated. Diet 1 served as control containing raw Mucunal, while diets 2, 3, and 4 had boiled Mucuna, Mucuna boiled with ankanwu and boiled Mucuna mix with enzyme, respectively added to them at 5% level of inclusion. The birds were allowed 7 days to get stabilized before being randomly assigned to the experimental diets that lasted for 49 days. The crude protein content of the raw was significantly higher (P<0.05) than that of the boiled and boiled with potash. Processing reduced the energy content of raw Mucuna seed from 4.73 Kcal/g (raw) to 3.90 cal/g(boiled) and 3.81Kcal/g (boiled with akanwu, BWA). Boiled MSSM had a significantly (P< 0.05) higher content of Na, K, Ca, P and Mg, than that of BWA. The calcium (1.87) content of the boiled was significantly (P<0.05) higher than that of the raw (1.665). There were significant (P<0.05) increases in Fe, Cu, Zn and Mnin the processed over the raw.BWA resulted in a significantly (P<0.05) higher decrease in anti-nutritional content of the seed. B Mucuna sloanei Mucuna akanwu. Mucuna sloanei, sesquioxid soiling method is selected as the best method of detoxification for seeds since it was able to make 84.18% reduction of L-DOPA which is the major anti-nutrient in and 98.40% reduction of trypsin inhibitor a wide spread anti-nutrient among legumes. In addition it is amethod of detoxification that can be well adapted to by the local farmers as against that of boiling with potash which involves the preparing of potash solution and additional cost
