Theme 21: Forage Conservation
Description
The experiment was conducted to study the effect of ozone treatment on the feed value of cotton stalk, wheat straw and rice straw. These feeds were cut into 2 cm and 4 cm lengths, and rolled before ozonizing. The ozonizing periods were 30 min. 60min and. 120 min. The Acid Detergent Lignin (ADL) concentration of the feeds decreased with ozone treatment. Except for rice straw, the short cutting treatment (2cm) decreased the concentration of ADL and Cellulose of the ozonized cotton stalk and wheat straw. Rolling and ozone treatment were effective in decreasing the ADL concentration of cotton stalk. IVDMD (In Vitro Dry Matter Digestibility) of feeds rose 17 points in the cotton stalk, 4 points in the wheat straw and the rice straw with ozonizing. The short cut (2cm) cotton stalk and the wheat straw showed an increase in IVDMD but the rice straw showed no change. Rolled and ozonized cotton stalk was the only feed to show a rise in IVDMD. The concentration of ADL and Hemicellulose of all feeds decreased with ozonation but the IVDMD was related to the decrease in the contents of ADL of feeds. The higher ADL concentration in the feeds, higher the ozonation effect.
