This study was conducted to improve the quality of the water hyacinth silage. Rice bran and wheat bran are the by-product of the agricultural system and may have the potentiality to improve the fermentation and palatability of silage. The fresh water hyacinth material was wilted to about 70 moisture content by sun drying. Then the wilted water hyacinth was mixed with 0, 5, 10, 15 and 20% of rice bran or wheat bran in the polyethylene bottles, respectively. The silage quality was evaluated after 4 weeks of ensiling. The pH value, lactic acid, butyric acid and ammonia-N/total-N contents of the silage added rice bran ranged 5.2-4.7, 1.3-3.7%, 0.3-0.1% and 5.6-3.1%. respectively. On the other hand, those of the silage added wheat bran were 5.2-4.6, 1.3-4.1%, 0.4-0.2% and 7.8-3.9%, respectively. This result showed that the silage with more than 15% of the additive had high qualities in both rice bran and wheat bran treatment and the addition of wheat bran was slightly better than that added rice bran in silage quality.
