Abstract

Statement of the Problem: The aim for this research was to study the effect of different additives and concentration on oat silage. Selected Dancer as material was used for silage in milk stage, and four kinds of additives respectively at different concentration were used. They 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). The 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 fiber) 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. The best concentration of different additives were that: lactobacillus (5 mg/kg), formic acid (5ml/kg), sucrose (2%) and the influence on silage quality have no close connection with concentration when added cellulase.
