Abstract
Statement of the Problem: Th e aim for this research was to study the eff ect of diff erent additives and concentration on oat silage.
Selected Dancer as material was used for silage in milk stage, and four kinds of additives respectively at diff erent concentration were
used. Th ey were lactobacillus (0 mg/kg, 1 mg/kg, 5 mg/kg, 10 mg/kg), formic acid (0 ml/kg, 1 ml/kg, 5 ml/kg, 10 ml/kg), sucrose (0%,
1%, 2%, 4%) and cellulose (0 mg/kg, 50 mg/kg, 100 mg/kg, 150 mg/kg). Th e materials were ensiled at room temperature and opened
60 days later, and the fermentation quality and the chemical composition were analyzed. Results showed that it had a positive impact
on Dancer silage with four kinds of additives. Considering nutritional value index(crude protein, ether extract and crude fi ber) When
cellulase were applied at 50 mg/kg, the oats silage were excellent. Considering silage quality indexes of pH value, AN/TN, soluble
sugar content and lactic acid content, sucrose at 2% level was the best concentration. Th e best concentration of diff erent additives
were that: lactobacillus (5 mg/kg), formic acid (5ml/kg), sucrose (2%) and the infl uence on silage quality have no close connection
with concentration when added cellulase.
