A study was conducted to assess the proximate composition, phytochemicals, and mineral components of the pod, leaf, and seed of the Parkia biglobosa (P. biglobosa) tree, with the aim of determining their suitability as animal feed resources. The findings revealed that the seed exhibited significantly higher (P < 0.05) levels of crude protein (CP) and ether extract (EE) compared to the leaf and pod. Specifically, the seed recorded the highest values (P < 0.05) for CP (15.31±0.03) and EE (13.23±0.04), while the pod displayed the lowest values of 3.91±0.12 and 0.89±0.04 for CP and EE, respectively. The pod registered the highest values (P < 0.05) for crude fiber (CF) and nitrogen-free extract (NFE) with respective values of 8.85±0.1 and 75.14±0.11. Conversely, the leaf exhibited the highest (P < 0.05) ash content, while the seed had the lowest ash value (1.99±0.04). In the mineral analysis, the seed and pod had the highest values (P < 0.05) for calcium (Ca) and phosphorus (P), respectively. Phytochemical screening results indicated that the pod contained the highest values (P < 0.05) of alkaloid (19.06±0.09) and tannin (10.97±0.08), while the leaf showed the highest values (P < 0.05) for saponin (34.20±0.25) and hydrocyanic acid (HCN) (2.22±0.30). The overall conclusion drawn from this study suggests that all three parts of P. biglobosa (seed, pod, and leaf) have the potential to serve as alternative feed resources for livestock.
