Improving silage characteristics in high-moisture grape residues using cotton stalk as a moisture regulator.

ABSTRACT: Grape branches and leaves are promising feedstock for high-quality silage, yet their high moisture content limits effective fermentation. This study aimed to investigate the effect of cotton stalk addition on fermentation quality and microbial characteristics of high-moisture grape branches and leaves silage, providing a basis for the efficient utilization of these resources as animal feed. The experiment included six treatments with different levels of MG (cotton stalk) : 0% (MG0), 10% (MG10), 20% (MG20), 30% (MG30), 40% (MG40), and 50% (MG50). After 60 days of silage fermentation, increasing MG proportion significantly reduced silage moisture content (P < 0.05), while pH and acetic acid (AA) levels significantly increased (P < 0.05). Bacterial community analysis revealed that the dominan
