Effects of additives on fermentation quality of corn silage from different regions

In order to investigate the effects of additives on fermentation quality of corn silage from different areas, North 410 variety planted in Harbin (HB), Chifeng Linxi (CF), Hohhot (H), Hebei Hengshui (HS) and Ningxia Yinchuan (YC) were taken as research subjects. The control group treatments of lactobacillus (0.000 5%) and treatments of cellulose treatments (0.001 5%), silaged in bags under vacuum were set separately and analysis was made after 45 days. The results showed that lactobacillus and cellulase treatments significantly lowered the pH value and acetic acid content, while boviously increased the lactic acid content (P0.05), and improved the fermentation quality and nutritional value of silage. Additive treatments significantly reduced NDF and ADF contents of corn silage (P0.05). The WSC contents of lactobacillus treatments in Harbin, Hengshui and Yinchuan were significantly increased (P0.05) and those in Yinchuan was the highest. The corn silage fermentation quality Flieg level of all areas were excellent.
