PROXIMATE ANALYSES OF SELECTED BROWSES OF SOUTHEASTERN NIGERIA

Abstract

This study evaluates the proximate composition of selected browses common in southeastern Nigeria and their endogenous uses, assessing their nutritional value and socio-economic importance. These species belong to different families including; Anacardiaceae, Bombacaeae, Burseraceae, Caesalpiniaceae, Memosaceae, Moraceae, Plamaea and Rutaceae with notable representatives such as Anacardium occidentale (cashew), Dialium guineense (Velvet tamarind), and Elaeis guineensis (oil palm). Proximate analysis showed significant variations in crude protein (CP), crude fiber (CF), and ether extract (EE) content. Albizzia ferruginea Dialium guineense and Dacroydes edulis were highest in protein levels (32.77, 19.74 and 19.69% respectively), making them good nitrogen sources for ruminant diets. Elaeis guineensis contained the highest ether extract value (6.80%), suggesting its potential as an energy-rich feed material. Citrus sinensis, Ficus elasticodes and Millitia excelsa on the other hand revealed high ash content (12.50, 13.60% and 12.00 respectively), suitable for supplementing essential minerals in livestock diets. These browses were also reported to offer economic, medicinal, and ecological benefits beyond their nutritional values. Acacia senegalensis and Albizzia ferruginea have termite-repellent and antimicrobial properties, while Elaeis guineensis and Dacroydes edulis provide fuel, timber, and edible fruit. In conclusion, these indigenous browse species are valuable for enhancing livestock productivity and sustainable animal production considering their nutritional values. Future research should investigate the effects of incorporating these browses into animal diets and their role in mitigating seasonal feed shortages in developing countries.
