Evaluation of the nutritional and anti-nutritional constituents of some selected browse plants in Kwara State, Nigeria
Abstract
Fresh leaves and apical parts of the selected browse plants: Chromolaena odorata, Mangifera indica, Anacardium occidentale, Synedrella nodiflora, Azadirachta indica, Tridax procubens, Ficus congensis, Amaranthus spinosus, Hyptis suaveolens, Carica papaya were collected in Ilorin, Kwara State, Nigeria and analyzed for proximate composition and some anti-nutritive component of their leaves.
A high variability was recorded in values of percentage crude protein (C.P.), the range in CP, Ash, CF, Ee, NFE and DM were 5.40 – 33.10g/kg DM, 3.00 - 34.57g/kg DM, 6.13 - 30.50g/kg DM, 1.50-13.30g/kg DM, 10.03 – 61.97g/kg DM and 54.92
– 96.54g/kg DM respectively.
The concentration of antinutritional factors were generally low, tannin content was 0.55% in Chromolaena odorata and 5.90% in Synedrella nodiflora, phytin content was 0.083 mol kg -1 in Hyptis suaveolens and 1.99 mol kg -1 in Synedrella nodiflora. Oxalate content was 13.93mg/100g in Tridax procumbens and 121.67mg/100g in Chromolaena odorata while hydrocyanic acid, HCN content were 49.95 mg/kg in Amaranthus spinosus and 201.83 mg/kg in Mangifera indica.
The result showed that the browse plants studies had good levels of nutrient, low and safe level of antinutritional factors, and may therefore form good feed resource for modern intensive animal production.
