Nutritive Values of Some Tropical (West African) Legumes for Poultry

Abstract

An experiment was conducted to establish the effect of increasing the dietary amounts of jackbeans, kidneybeam, limabeans, yambeans, pigeon peas and bambara groundnuts on the performance of broiler chickens. The inclusion of legumes even at 12.5% level resulted in signijkant decreases in weight gains and feed intakes. The amount of feed consumed (ks;, per kg weight gain for broilers offered diets containing 12.5% lima beans, pigeon pea and 12.5 or 25% bambara bean or yam bean did not differ signijicantly from control group. Inclusion of jack bean and kidney bean at both the levels and lima bean or pigeon pea at 25% level adversely affected the effi.ciency of feed conversion. The weights of liver and brain were significantly (P<0.05) altered by higher levels of dietary treatments. Serum total protein and albumin levels generally decreased with 25% legume concentration in the diets but urea and creatinine levels increased Transaminase and phosphatase enzyme activities were genemlly elevated on higher level of legume feeding. Thus only pigeon pea and bambam nut can be recommended for inclusion in poultry rations. But vigil is needed if it is proposed to be fed over a longer period

The Growth and Mineral Utilization of Clarias Gariepinus Fingerlings Fed Phytase-Supplemented Toasted Lima Bean (Phaseolus lunatus) Diets

“…The complete elimination of trypsin inhibitor by toasting agreed with the report of Ologhobo [18] where heat treatments such as toasting, autoclaving and cooking were shown to destroy heat-labile anti-nutritional factors. However, toasting only resulted in about 10% reduction in phytate content, which is similar to the 9.3% reduction reported in Falaye et al [16].…”

Nutrient content of Bambara groundnut (<i>Vigna subterranea</i>) and the effects of its inclusion on the performance of growing broiler chickens and on egg production and quality

“…The CP and crude fi bre content of Bambara groundnut determined in this study were about 22 and 5.2%, respectively, similar to those reported from other studies (Nwokolo, 1987;Ologhobo, 1992). However, the content of ether extract (7.5%) in this study was much higher than the 2.85 % reported by Nwokolo (1987).…”

“…However, the content of ether extract (7.5%) in this study was much higher than the 2.85 % reported by Nwokolo (1987). The similarity in the nutrients content from this study to those of Nwokolo (1987) and Ologhobo (1992) could be due to the fact that the nuts all originating from the same geographical region (West Africa). The differences in the nutrient content found in this study to those reported by the authors in the introduction could be to a large extent due to the geographical origin and also the cultivar used.…”

“…In a study Ologhobo (1992) reported that feed intake of broilers fed 12.5% Bambara groundnut was not signifi cantly different while, at 25% level, it was signifi cantly lower than the control group. Similar trends have also been reported in other species of Vigna.…”

“…On broilers, Oluyemi (1975) reported an ME content of 8.2 MJ/kg, while Nwokolo (1987) 12.5 MJ ME/ kg and a true protein digestibility of 77%. Ologhobo (1992) tested 12.5 and 25% levels of inclusion of Bambara groundnut in growing broiler rations and concluded that at the 25% level the performance was signifi cantly reduced. Fru Nji et al (2003) reported a feed/gain ratio of about 2.1 and an apparent protein retention of about 50% for Bambara on growing broiler chickens.…”
