Water hyacinth, Eichhornia crassipes, is an invasive aquatic weed that covers major water bodies in Nepal, and its silage has great potential to be used as ruminant’s feed. An experiment was conducted with an aim to explore its ensiling attributes along with palatability test for cattle was conducted at Institute of Agriculture and Animal Science, Rupandehi in a completely randomized experimental design with three replications. The quality and palatability of water hyacinth silage prepared with additives such as rice straw, molasses, wheat flour, and rice bran were assessed. The treatments included: water hyacinth with rice straw(T1); water hyacinth with rice straw and rice bran(T2); water hyacinth with rice straw and wheat flour(T3); water hyacinth with rice straw and molasses(T4); water hyacinth with rice straw, wheat flour and molasses(T5); water hyacinth with rice straw, wheat flour and rice bran(T6) and water hyacinth with rice straw, wheat flour, molasses and rice bran(T7). The results showed, crude protein (CP), crude fiber (CF), ether extract (EE), total ash (TA), pH, and palatability had significant differences across all treatments (p<0.05). CP (15.13) and CF (23.73) were found to be highest under control whereas rice straw, wheat flour and rice bran had the highest EE (12.74), TA (15.13), pH (3.87), palatability (100%), and considerably high CP (12.40) and CF (19.75). Hence, silage of water hyacinth with rice straw, wheat flour, and rice bran has high nutrient content, palatability and can be used as a feed alternative to solve the problem of feed scarcity.
