Purpose -African yam bean (Sphenotylis stenocarpa), bambara groundnut (Vigna subterranean), pigeon pea (Cajanus cajan) and lima bean (Phaseolus luunatus) are some of the minor grain legumes found in Nigeria. Their utilization has been very limiting because little is known about their nutritive value. The proximate, minerals and antinutritional factors of two collections of African yam bean, lima beans and pigeon pea, and one collection of bambara groundnut seeds grown in south-western Nigeria were studied. Design/methodology/approach -Dry seeds of two collections of African yam bean, pigeon pea and lima beans, and a collection of bambara groundnut were collected from Oyo and Ondo States in south-western Nigeria. The legumes were sorted, milled and stored in polythene bags at 4˚C. Findings -The crude protein in the legumes was in the range of 22-37 per cent, crude fat 1.47-4.96 per cent, crude fibre 1.92-7.21 per cent and ash 3.33-5.61 per cent. K, Ca and P were in the range of 0.15-0.52 per cent. Iron content of the seeds was very low. The antinutrients, tannin, phytic acid and trypsin inhibitor were very high when compared to those of cowpea, groundnut and soybean. Originality/value -It therefore implies that consumption of these legumes will require processes that will reduce their antinutritional factors.
PurposeIn the livestock industry in Nigeria, maize is a major source of energy and it is expensive because of competition between man and animal. Dry plantain peel of minimal cost was used to replace the maize fraction of the diet of rabbit in order to reduce cost. The purpose of this paper is to examine the performance characteristics of rabbit fed plantain peel.Design/methodology/approachThe feeding trial had five treatments, T1, T2, T3, T4 and T5 in which the maize fraction in the diet was replaced at 0, 25, 50, 75 and 100 per cent, respectively. Completely randomized designs were used and each treatment was replicated thrice with three rabbits per replicate. The parameters taken were feed intake and weight gain on a daily and weekly basis. Feed conversion ratio, total feed cost and cost per weight gain were calculated.FindingsThe results show that there was no significant difference in the weight gain between the control diet (T1) and T3 (p < 0.05). The feed conversion ratio was relatively similar in T1 and T4. The cost per weight gain reduced from N53.57 in the control diet to N33.39 in T3 (75 per cent replacement).Originality/valueIn the livestock industry, maize is expensive because it serves as food for both man and animal. The results indicate that the feed cost of rabbit could be reduced by replacing the maize fraction of the diet with 75 per cent dry plantain peel.
