Effect of additives on the quality of Asparagus officinalis stem leaf silage

Abstract

Abstract: The objective of this study was to investigate the effects of different additives on the quality of Asparagus officinalis silage (stem and leaf). Lactobacillus, lactobacillus+cellulose, lactobacillus+rice bran and lactobacillus+cellulose+rice bran were added to silage; the concentration of lactobacillus, cellulose and rice bran were 5×10⁵ cfu/g, 0.6 IU/g, 30 mg/g of fresh weight respectively. After being ensiled for 90 days, the quality of A. officinalis stem leaf silage was assessed. The chemical composition, pH, NH₃-N and organic acid content of fermented juice were analysed. The data showed that, compared with the control group, the addition of lactobacillus increased the acetic acid content, reduced aerobic deterioration (P<0.05) and improved the aerobic stability. Lactobacillus with rice bran and cellulose tended to lower the quality of A. officinalis stem leaf silage. The results demonstrated that high quality A. officinalis stem leaf silage can be obtained with addition of lactobacillus only.
