ABSTRACT
The biomass yield of water hyacinth (WH) was studied in three purposively selected water bodies in Nigeria. Its nutritive potential was undertaken through analysis of chemical components. Biomass yield of WH ranged from 28.80 to 33.20 tons DM/ha/yr from one location to another with a significant difference. The proximate analysis showed 90.16, 10.01, 22.75 and 14.98 g/100g DM for moisture content, crude protein, crude fibre and ash respectively. The fibre detergent fractions were NDF, 44.50; ADF, 28.00 and ADL, 2.76 g/ 100g DM. The Ca, P, Mg, K and Na contents were 3.08, 0.28, 0.65, 4.13 and 0.13 g/100g DM respectively while those for Mn, Fe, Cu, Zn, Co and Pb were respectively 1738.69, 2387.98, 10.97, 69.18, 3.03 and 5.83 mg/kg. Levels of Ca and K were noticeably high. The result showed that WH is available all year round and could provide nutrients and minerals to be utilized as fodder for ruminant especially during the dry season.
