Fermented wheat and rice straws reduce methane production and improve nutrition.
The researchers studied how fermenting wheat and rice straw with urea affects methane production and degradability. They found that fermenting the straws increased protein content and decreased hemicellulose, without changing lignin. Fermented rice straw produced more methane than wheat straw. Fermented straws had higher nutrient digestibility and energy availability. Methane production was lower in fermented straws. Fermentation also increased the digestibility of nutrients in the straws. Overall, fermenting straws with urea improved their quality and nutritional value.
