Potential of shea fruit-based ingredients for the feed industry

Abstract

Abstract Background The cost involved in feeding poultry is very high especially in most developing countries. To this end, the effectiveness of the fruit pulp of Vitellaria paradoxa (shea), an agro-industrial by-product that is discarded in the processing of the nut for shea butter extraction was investigated on twelve poultry birds assigned to three groups A, B and C (control). Dried samples of the fruit pulp were analysed for their nutrients. Results Proximate analysis of the shea fruit pulp revealed a carbohydrate content of 41.14%, crude fibre 26.62%, crude protein 10.34%, ash 9.23%, crude fat 3.55% and 9.13% for moisture. It also contained essential minerals such as Ca (587 mg /100 g dw), Na (138.30 mg /100 g dw), Mg (1358 mg /100 g dw), K (771.5 mg /100 g dw), Fe (29.88 mg/100 g dw), Zn (40.31 mg/100 g dw) and Cu (8.11 mg/100 g dw). Heavy metals such as Cd, Mn, Pb and Cr were below detectable limits. Measured parameters were live body weights and some selected blood chemistry tests. Broilers in groups A and B fed on shea fruit pulp formulated with maize meal showed a significant growth performance in weight (p 0.05) in the control group, fed on maize meal only. Conclusion The fruit pulp of Vitellaria paradoxa could be considered a good source of macro and micronutrients and could be used as a supplement in poultry feed.
