How to Convert Corn Stalks into Cattle and Sheep Feed
Corn stalks are a primary feed for cattle and sheep, and there are various methods to process them into feed. Here, we introduce two methods.
One,Packed Feed
Corn stalks, once matured from the打包饲料packaged feed, are crushed and then formed into bales. The dimensions of the square bales are generally:The packaging dimensions are 290*320*700mm. The packed feed is divided into two types: green storage and yellow storage.
Corn Stalk Baling Feed is a process that involves bundling corn stalks as the corn ears approach maturity.The "green silage forage harvester" crushes the forage, then the "green silage straw briquette press" compresses it, reducing the volume and expelling air between the straws. Meanwhile, the molded compressed straw bales after compression are sealed with plastic sheets and woven plastic bags. The shelf life of this straw feed product is generally three months. Its advantages include high nutritional content in the feed and low cost. The drawback is that it cannot be produced and stored in large quantities.
Yellow Corn Stalk Baling Feed is a type of feed product formed by粉碎, sieving soil, and compressing corn stalks after harvesting the corn ears in autumn. The general production process is as follows: once the corn stalks in the fields mature, the ears are first harvested using a corn harvester. Afterward, the stalks are left in the fields until their moisture content is below...Approximately 35% of the corn stalks are baled by the corn stalk baling machines. After baling, the corn stalks are transported to a blockage station for compression. Before compression, the stalks must pass through a shredder (it's crucial to choose a shredder with a bottom discharge sieve), the drum sieve to remove soil, and then are compressed and packaged by the straw block press. The shelf life of this straw feed product is generally six months. (Most packaged feed should be used up before May 1st each year, as temperatures rise after this date, the moisture content of the packaged feed exceeds 18%, making the forage prone to spoilage.) The advantages are low product cost and ease of storage, but the downside is high transportation costs over long distances.
Two: Pellet Feed
Pelleted Feed, also known as compacted feed."The 'Grass Ball' is a new type of livestock feed, introduced to the market in recent years, known for its long-term storage capabilities and ease of transportation over long distances."
Its production process is similar to that of yellow storage straw baling feed. The difference is that yellow storage straw baling feed isThe rectangular package measures 290*320*700mm, while the compressed feed blocks are approximately 32*32*50mm in size. Additionally, the density of the compressed feed ranges between 0.6-0.9 kg/dm³, significantly higher than that of compressed feed. Its advantages include being semi-processed through the high-temperature (usually around 100℃ for export) compression of the straw compression machine, resulting in a finished product with a moisture content below 15%, suitable for long-term storage, typically over two years. Moreover, the crushed corn straw, after being compressed by the machine, has a particle size below 2 cm, making it ideal for cattle and sheep consumption. In summary, the benefits of compressed feed are: 1. Long shelf life; 2. Low transportation costs; 3. Good palatability.
