Effect of feeding velvet beans (<i>Mucuna pruriens</i>) on the lipid profile of broiler chickens

Abstract

The effect of feeding velvet bean (Mucuna pruriens) meal on the lipid profile in broilers was investigated. Two hundred, 14 days old broiler chicks were randomly allocated to five dietary treatments in a completely randomized design and feeding continued for four weeks. Maize and soybean meal based control feed and four test diets prepared from the control feed by incorporating velvet beans at 10, 15, 20 and 25% levels served as five dietary treatments. Feed intake was unaffected by velvet beans. Serum total cholesterol level was lowered by 9.5, 9.7, 15 and 16% in birds fed with 10, 15, 20 and 25% velvet bean diets. Birds fed 25% VB diet showed an increase in HDL level by 8%. LDL level was lowered by 43.1, 36.5, 25 and 23.4%, respectively in birds fed with 25, 20, 15 and 10% velvet beans. Velvet beans reduced the serum triglyceride levels. Results suggest that Velvet beans contain a strong cholesterol lowering effect in broilers.

Response in Growth Performance, Physico-chemical Properties, and Fatty acid Composition of Broiler Meat to Different Levels of Mucuna Pruriens Seed Meal

“…Average daily feed intake showed a linear decrease with increasing inclusion levels of MPSM. Our results are in agreement with (Carew et al, 2003;Jayaweera et al, 2007) who also reported a decline in average daily feed intake of broilers. Generally, heat processing results in detoxi cation of the anti-nutritional factors (ANFs), hence, enhancing protein absorption, bioavailability of the amino acids in the gut and higher palatability ; Tuleun and Igba, 2008; Gurumoorthi and Uma, 2011).…”

“…To reduce the quantity of soybean meal used when formulating poultry diets, M. pruriens seeds can be used as a protein source and as a source of lysine which is one of the limiting amino acid that is usually supplemented in broiler diets (Jayaweera et al, 2007;Ani, 2008;Vadivel and Pugalenthi, 2010). However, its effect on meat quality has not been investigated, as it has been found that dietary ingredients affect meat quality (Mir et al, 2017).…”

“…Other researchers have explored the use of MPSM as a protein source in broiler diets in some parts of Asia and East Africa (Del Carmen et al, 1999;Iyayi and Taiwo, 2003;Nyirenda et al, 2003;Jayaweera et al, 2007;Ani, 2008;Vadivel and Pugalenthi, 2010;Mangwiro et al, 2013). The focus has mainly been on its potential bene ts as an alternative source of protein on the growth performance of birds, little has been reported on its effect on the quality fatty acid composition of broiler meat.…”

Dietary supplementation of low levels of unprocessed Mucuna pruriens utilis seed meal induces mild antinutritional entero-physio-metabolic perturbations without compromising performance and meat quality in finisher broilers

“…Hence, consumption of MSM induces anabolic effects and increases muscle mass mediated through its ability to increase growth hormone (Alleman et al, 2011 ), testosterone (Suresh and Prakash, 2012 ), and dopamine (Lieu et al, 2012 ). Also, consumption of MSM has been demonstrated in poultry and rodent studies to induce hypoglycemic, lipid, and low-density lipoprotein cholesterol lowering effects (Jayaweera et al, 2007 ; Dharmarajan et al, 2012 ; Ngatchic et al, 2016 ). Further, MSM incorporation into beef diets has been shown to decrease meat cooking losses (Yantika et al, 2016 ).…”
