The present study was conducted to find out the nutritional values of
Faidherbia albida
(
Acacia albida
) seeds and pulp to be used as components in livestock feeds. The samples were randomly collected from various trees during the period of January to February. The samples were separated, milled and analysed for proximate components and mineral elements using standard methods of the AOAC. Proximate analysis results showed that the concentrations of tested parameters in the seed and the pulp respectively on % dry matter were: dry matter (90.0 ± 0.4; 93.3 ± 0.2), ash (3.3 ± 0.1; 6.7 ± 0.1), crude protein (20.6 ± 1.2; 19.5 ± 0.4), crude lipid (13.3 ± 0.1; 3.3 ± 0.1), crude fibre (6.7 ± 0.1; 13.3 ± 0.2), and available carbohydrate (46.1 ± 0.1; 50.53 ± 0.7). The results indicated that the contents of dry matter, ash, crude fibre and available carbohydrate were significantly higher (p < 0.05) in the pulp compared to the seed while the crude lipid values, however, were significantly higher (p < 0.05) in seeds compared to pulp. Crude protein values did not differ significantly (p > 0.05) between treatment means of seeds and pulp. The estimated energy value was significantly higher (p < 0.05) in the seed (1,682 kJ/100g) compared to pulp (1,363 kJ/100g). The results for the mineral analysis indicate that the seeds and pulp contain appreciable concentrations (mg/100g) of Ca (136.6 ± 5.0; 55.0 ± 5.0); Mg (135.0 ± 2.0 ± 5.0; 84.7 ± 3.0); P (26.6 ± 0.9; 29.6 ± 0.7); K (144.5 ± 0.2; 88.8 ± 0.1); Na (12.5 ± 0.1; 6.8 ± 0.1); Fe (6.2 ± 0.2; 8.8 ± 0.3); Cu (5.8 ± 0.1; 2.5 ± 0.1) and Zn (8.0 ± 0.1; 3.0 ± 0.1). Mineral elements in seed are significantly higher (p < 0.05) compared to that of pulp in most cases. From the results it can be inferred that the seed and pulp of
F. albida could be an important source of feed ingredient for livestock if properly harnessed.
