ABSTRACT
Availability of pasture during prolonged dry season is uncertain in Nigeria. Hence the need for pasture preservation during the period of lush growth. Silage making is one of the options available. Water hyacinth (WH) is readily available in the rivers, streams and lagoons in Nigeria. Nutritive value and coefficient of preference (COP) of ensiled WH was evaluated using agro-industrial by-products; namely, Dried brewer grain (DBG), Palm kernel cake (PKC) and Wheat offal (WO) as additives to prepare WH-based silages. Fermentation was for 42 days. Silages were fed to WAD sheep to determine preference. The WHS had a pH of 9.3, while other silages (those with additives) had a pH range of 4.34.7, a firm texture, pleasant odour and yellow-brown colour. The proximate composition of all four silages varied significantly and ranged: crude protein, 7.316.2; crude fibre, 12.424.4; ash, 9.0026.8 and ether extract, 8.214.4 (g/ 100 g DM). Results of the COP for the silages ranged from 0.051.09 and could be ranked in order of preference as WHPKS>WHBDGS>WHWOS>WHS. The use of dried brewer’s grain, palm kernel cake and wheat offal as additives resulted in properly fermented water hyacinth silages which were adequate in nutrients and highly accepted by sheep.
