Lactic acid bacteria are anaerobic (oxygen) bacteria that cannot multiply in the air. Moulds and some bacteria are mostly aerobic bacteria. Therefore, silage is chopped, compacted, and sealed to minimize pits and towers. The air inside or inside the bag creates conditions for the growth and reproduction of lactic acid bacteria and the eradication of spoilage bacteria. In addition, another function of chopping is to release more soluble sugar from the raw material for fermentation and utilization by lactic acid bacteria. Silage suitable moisture is 65%, the change range is 60% ~ 70%, if the water content is too high, then the sugar is excessively diluted, not suitable for the propagation of lactic acid bacteria, water content is too low, the silage is not easy to compress, residual air is too much , Fungus and other germs breed and spread, resulting in higher heat, browning the feed, reducing the digestibility of the protein, resulting in deterioration of silage rot. The minimum content of good silage soluble sugar is 2%. When the silage raw material sugar content is insufficient, it should be mixed with green plants with higher sugar content and mixed and pressed. If necessary, the appropriate amount of molasses, starch, and serum may be added. General grasses have a high sugar content, such as corn and sorghum. Legumes have a low sugar content, such as barnyardgrass and sandgrass. The most suitable temperature during the silage process is 20°C and the highest temperature is 37°C. The temperature is too low, indicating that the life activity of lactic acid bacteria is retarded. If the temperature is too high, the lactic acid content is relatively reduced and the loss of nutrients is also greater. To control the temperature of the silo, it is necessary to chop and chop the short silage material, step on the silage, and prevent the plant cells of the silage material from using the residual air to continue the respiratory oxidation, decompose the carbohydrates to release heat, and increase the cellar temperature. Promote growth and reproduction of germs and reduce silage quality. Shanghai J.Shine Co.,Ltd , https://www.jshinechem.com
