Studies on the incorporation of velvet bean (Mucuna pruriens var. utilis) as an alternative protein source in poultry feed and its effect on growth performance of broiler chickens

Abstract

The effect of replacement of soybean meal by the velvet bean meal as an alternative protein ingredient on the growth performance of broiler chickens was investigated. The raw seeds of velvet bean [Mucuna pruriens (L.) DC. var. utilis (Wall. ex Wight) Baker ex Burck], an under-utilized food legume collected from South India, was found to contain appreciable levels of crude protein (273.2 g/kg DM), lipid (60.61 g/kg DM), neutral detergent fiber (84.3 g/kg DM), and ash content (56.04 g/kg DM). Soaking in 0.2% sodium bicarbonate solution + autoclaving treatment caused a substantial reduction on the levels of various antinutritional compounds such as tannins (84%), L: -Dopa (79%), phytic acid (87%), raffinose (93%), stachyose (83%), verbascose (73%), haemagglutinating activity (84%), trypsin inhibitor activity (77%), and alpha-amylase inhibitor activity (78%) without affecting the nutritional quality of velvet bean seeds. The processed velvet bean meal was incorporated as an alternative protein source by replacing soybean meal protein at 0, 20%, 40%, 60%, 80%, and 100% levels in the broiler diets. Replacement of soybean meal protein up to 40% level, which corresponds to the inclusion of velvet bean meal up to 15.7% and 11% in the starter and finisher phase poultry feeds, respectively, exhibited better growth performance of broiler birds without any adverse effects.

“…However, for those fed on 15% BSOC, the low gross margin may have been because of the interaction of their FI and BW. They did not consume much feed owing to the fibre and anti-nutritional content of the diet as a result of incremental levels of these elements from increased inclusion of BSOC (Nkafamiya et al, 2007;Vadivel & Pugalenthi, 2010;Sebola et al, 2015). Nevertheless, they managed to consume enough feed to meet their dietary needs, as shown by their high FCR (Nahashon et al, 1997;Veldkamp et al, 2005).…”

“…This may be attributed to the alleged healthiness of chicken, higher profit margins over a short period, and high acceptability of poultry products in many culinary traditions (Rao et al, 2006;Sola-Ojo et al, 2013). According to Vadivel & Pugalenthi (2010) and Bampidis & Christodoulou (2011), there has been high competition for the consumption of traditional protein sources between human beings and the livestock industry in the last two decades, which has resulted in an inadequate supply of dietary proteins. As such, soybean has been the primary dietary source of plant protein, although currently its production has not been sufficient to meet the protein demands of the increasing human population and expanding livestock industry (Saulawa et al, 2014).…”

Androgenic and Anabolic Possibilities of Mucuna Pruriens

“…However, there are anti-nutritional factors (AF) in their composition, such as tannins, phytic acid, enzyme inhibitors, trypsin, saponins, lectins, hemagglutinin activity [1,7,15] and a high content of L-dopa, which makes it extremely toxic and unfit for human consumption. Common methods to eliminate anti-nutritional factors include cooking, roasting, drying, fermentation, alkaline solubilization, isoelectric precipitation [16] or ionizing radiation [17].…”

“…MP is widely used in Ayurvedic medicine, Indian traditional treatment [15]. The most known use of MP is the treatment of Parkinson Disease.…”

Influence de la substitution graduelle de tourteau de soja par la féverole sur la croissance et la conformation de la carcasse chez les poulets de chair

“…Ces protéines sont riches en lysine, mais assez pauvres en acides aminés soufrés et tryptophanes. Vadivel et Pugalenthi, (2010) ont utilisé plusieurs méthodes afin de déterminer la composition de la féverole. A l'aide de la méthode micro Kjeldahl et la méthode soxhelt d'extraction, ils ont déterminé la teneur en protéines brutes et en lipide qui sont respectivement 265g et 65g /kg de MS. Ces valeurs sont relativement élevées par rapport à d'autres légumineuses ce qui contribue à utiliser la féverole comme une source protéique alternative pour réduire l'indépendance à la protéine du tourteau de soja.…”
