Analyze Of Bale Silage Manufactur Technique And Quality Control Of Natural Grassland Herbage

Pastoral areas of China actively promote the transformation and upgrading work on grassland animal husbandry modernization. Silage with nutrition saving rate is high, long storage period, the use of high efficiency has become the livestock forage processing and storage methods are equally important. The bale silage and pit method in natural grassland stretching film, convenient use, convenient transportation, high degree of commercialization. It is a forage supply mode for modern animal husbandry production.The research of silage technology at home and abroad of natural grassland, at home and abroad about the natural grass wrapping silage technology conditions of related technology, there is no standard reports. Therefore, this paper takes Inner Mongolia Hulunbuir Ewenki banner natural grassland for wrapping silage materials, explore the natural grass wrapping silage conditions and quality control technology, in order to bag silage and provide a theoretical basis and technical basis for the production of high quality natural grassland in.Tests the following conclusions:1. Different plants has different influence on complex grassland and the natural grassland pasture plants has complex constitute. So this paper choose five superior grass to study the effect of complex community,the conclusion is:Leymus chinensis>Artemisia scoparia> Stipa baicalensis Roshev>Medicag falcate>Iris lacteal var.chinensis.2. The bale silage of natural grassland herbage can control the grow of mould, Lactic acid bacteria, Aerobic bacteria and Escherichia coli and promote the growth and reproduction of Lactic acid bacteria; the Lactic acid bacteria was 6.38 log cfu/g after storage 10 days and then growth slow.3. From the bale silage of natural grassland herbage, identification seven bacteria of Lactobacillus(Lactobacillus plantarum), Lactococcus lactis (Lactococcus lactis), Grignard lactis (Lactococcus garvieae), Lactobacillus casei (Lactobacillus casei), Lactobacillus brevis (Lactobacillus brevis), Enterococcus faecalis (Enterococcus faecalis)and.feces enterococci (Enterococcus faecium), and the quantity of Lactobacillus(Lactobacillus plantarum) is the most.4. The best bale in this experiment is Imported bale with four tier and the density of 300～350 kg/m3.5. According to the result of single factor experiment, adding 1.5g/kg formic acid, 2ml/kg propionic acid,0.06g/kg lactic acid bacteria,0.8g/kg cellulose and 1 ml/kg formic acid+1ml/kg propionic acid+0.02g/kg lactic acid bacteria can guarantee good quality. But compare the single and complex additive, the formic acid+propionic acid+0.06g/kg lactic acid bacteria has the best result and lowest cost.
