Potential of citric and yeast waste fermentation products supplemented with fiber-degrading enzymes as alternatives to soybean meal in ruminant nutrition

Although the control diet performed best in terms of gas production and digestibility, the combination of CWYW and 0.4% fiber-degrading enzyme supplementation produced fermentation characteristics and digestibility values comparable to those of the control. These findings suggest that CWYW, particularly when supplemented with 0.4% enzyme, holds potential as a sustainable alternative to soybean meal in ruminant feed formulations.
