“…Autoclaving improved the proportion of CP not recovered in excreta and the metabolizabilityofenergyatalllevelsofinclusionofbambaragroundnut,givinglineartrends that had more gentle regression coefficients than those of the raw (CP: y = 57.9 -0.046x; R 2 = 0.90 and energy: y = 75.2 -0.139x; R 2 = 0.99). The increase in live weight gain caused by autoclaving is similar to those reported in other legume species (Olaboro et al, 1991;Gupta et al, 1991;Del Carmen et al, 1999). Bambara groundnut has been reported to contain ANF-like trypsin and chymotrypsin inhibitors, tannins and other polyphenols, phytic and oxalic acids, and also haemagglutinins (Odumodu, 1992;Oke et al, 1996;Apata and Ologhobo, 1997;Benjakul et al, 2000).…”

Bambara groundnut (Vigna subterannea)--a leguminous root nut, which grows in the tropics and subtropics--was used in an experiment to test its effect on the performance of growing broiler chicks. Performance was measured by monitoring growth, measuring nutrients and energy balances and also by determining nutrient accretion. Twelve-day old broiler chicks, kept in individual metabolic cages, were used in an experiment in which birds were equally allotted (n = 10) into a control (fed high performance diet made up principally of wheat and soybean meal) and 6 test groups fed diets containing 19, 76 and 95% raw or autoclaved bambara groundnuts. All diets were similar in energy, nitrogen and total lipid contents. Diets were also balanced for amino acids, vitamins and minerals in accordance to the specific requirements of the birds. Feed and water were provided ad libitum. Growth performance was monitored over 15 days. Nutrient and energy balances were measured by use of TiO2 as marker. The comparative slaughter technique was implored for the determination of energy and nutrient accretion. The results showed that the level of raw or autoclaved bambara had no significant influence on feed intake. Increasing the bambara level in the diets caused a general linear drop in the performance of the broilers. However, with up to 95% bambara in the diet, the general performance was still above 75% compared to the control. Increasing levels of bambara groundnut caused a decrease in the metabolizability of energy and efficiency of utilisation of ME for BWG. The animals retained more water with increasing levels of raw bambara in the diets while autoclaving increased their DM content to levels comparable to the control. The protein composition of gain was comparable at all levels of inclusion. In general autoclaving improved the performance of bambara.

“…Mortality in the birds was both erratic and nonsignificant. It shows it is not lethally toxic in the short run but produces toxicity effects that are chronic [128]. Emenalom and Udedibie [125] investigate the effect of raw, toasted, and boiled velvet beans on the performance of finisher broilers and observed that all the treatments affected the performance of broilers adversely, except the cooked seed meal, wherein the performance was good as that of the control diet.…”

Mucuna pruriens var. utilis, an underutilized tropical legume has a nutritional quality comparable to soya beans and other conventional legumes as it contains similar proportions of protein, lipid, minerals, and other nutrients. The beans have been traditionally used as a food in a number of countries, viz., India, Philippines, Nigeria, Ghana, Brazil, and Malawi. Recently, the velvet beans are exploited as a protein source in the diets of fish, poultry, pig, and cattle after subjected to appropriate processing methods. Although the velvet beans contain high levels of protein and carbohydrate, their utilization is limited due to the presence of a number of antinutritional/antiphysiological compounds, phenolics, tannins, L-Dopa, lectins, protease inhibitors, etc., which may reduce the nutrient utilization. Unfortunately, even though many researchers all over the world working on Mucuna, only scanty and conflicting information are available regarding its utilization as a food/feed and no scientific gathering to date has focused on the food/feed applications of Mucuna. Hence, the present review has been emphasized on the nutritional potential of this underutilized, nonconventional legume and current state of its utilization as food/feed for both human beings and livestock throughout the world.

“…However, the varied nature of most rations and suitable preparative/processing measures have been used to detoxify them. Many ANFs are heat labile (Kumar, 1991;Olaboro et al, 1991;Bressani, 1993). Hence, simple heating or autoclaving has been found useful in removing the effects of these allelochemicals.…”

African yambean (Sphenostylis stenocarpa, Hochst. Ex A. Rich, Harms) is an indigenous legume in tropical Africa. This food crop legume is highly under-exploited and very little scientific information is available in literature. In this study, the chemical composition (proximate, minerals and anti-nutritional profile) of raw and processed African yambean (AYB) seeds was investigated. Seeds of brown seed coat landraces of African yambean were collected from various locations in the Northern part of Cross River State. The seed characteristics were noted and subjected to boiling and toasting for one hour and thereafter evaluated for proximate composition, gross energy, mineral and antinutritional properties. Results showed that boiling significantly (P<0.05) increased crude Protein (CP) (22.10%), ether extract (EE) (7.53%) and gross energy (GE) (5.23 Kcal/g) compared to the raw (21.61% CP, 5.12% EE and 4.88 Kcal/g GE) as well as toasted seeds (21.41% CP, 5.195 EE and 4.51 Kcal/g GE). Toasting significantly (P<0.05) increased nitrogen free extract (NFE) (50.65%) and ash values. Processing (boiling/toasting) had significant (P<0.05) effect on mineral composition (Ca, Mg, K, Na and Fe) of the seeds except for phosphorus. Boiling significantly (P<0.05) reduced phytate (0.68%), alkaloid (0.70%) and trypsin-inhibitor (0.08 IU/mg) contents. Results have shown that African yambean seeds are rich sources of nutrients but have low human preference for food. But have a high potential as an energy/protein source in livestock feeds. The boiled AYB seeds had highest CP, mineral and lowest in anti-nutrient contents. Hence, boiling was the preferred processing method for AYB seeds.
