• Sucrose Supplementation Improves Alfalfa Silage Quality

  Researchers from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences investigated the effects of sucrose supplementation alone on ensiling characteristics and bacterial community compositions of alfalfa silage. It was found that the ensiling time significantly decreased the crude fiber content, and increased the ammonia nitrogen, acetic acid content, and the relative abundance of Enterococcus in the silages. Supplementing alfalfa silage samples with different doses of sucrose decreased their pH levels and NDF, propionic acid, and butyric acid content. There was an increment in the RFV levels with the increments of the sucrose supplementations. Furthermore, the reduced levels of butyric acid suppressed harmful bacteria and the relative abundance of Lactobacillus and Enterococcus in the silage increased. All results suggested that sucrose supplementation could improve increasing its beneficial bacterial content and the feeding quality of alfalfa silage.
