If you are a farmer to raise animals, i strongly recommend you to know more knowledge about the silage such as its features and principles. After being bundles by grass baling machine, it is not advisable to leave them for a long time, and you have to store them in a proper place so as that they won’t go moldy soon.
What ‘s the features of silage?
优质青贮饲料适口性好、维生素含量高、营养高。但青贮饲料的氮利用率往往低于其他饲料。青贮饲料是草食动物的基础饲料，其饲喂量一般不超过总采食量的30% -50%。
What’s the principle of silage?
青贮饲料在压实和密封后，内部缺乏氧气。乳酸菌发酵分解糖分后，二氧化碳进一步排除空气。分泌的乳酸使饲料呈弱酸性，pH值为3.5-4.2，能有效抑制其他微生物的生长。最后，乳酸菌也受到自身产生的乳酸的抑制，发酵过程停止。最后，饲料可以稳定储存。
What’s the requirement of silage?
青贮饲料原料含糖量要高
含糖量是指青贮饲料原料中可溶性碳水化合物的含量。是保证乳酸菌大量繁殖并形成足量乳酸的基本条件。青贮原料中的糖含量至少应为鲜重的1%至1.5%。
青贮原料必须含有适当的水分
适当的湿度是微生物正常活动的重要条件。水分过低会影响微生物的活动，导致细菌大量繁殖，使饲料发霉、腐烂。水太多和糖浓度低会导致饲料质量差。
同时，植物细胞汁液流失，营养损失较大。对于水分过多的饲料，应稍微干燥或添加干饲料与青贮饲料混合。当青贮原料含水量达到65-75%时，最适合乳酸菌的繁殖。
If you plant many crops, it is necessary for you to buy a grass baling machine that really can help you to fully take advantage of the crop straw.
