If you are looking for a lightweight, water-resistant, flexible, but strong cover, then a Bale Wrap Plastic is an excellent choice. Bales are generally available in three sizes, six feet, eight feet, and ten feet, although some specialist sizes are available. A typical bale will contain between twelve and eighteen inches of hay. It is possible to buy bales in several grades, including:
Livestock owners and growers have traditionally used white bale haylage as a source of bedding materials. However, there is now considerable demand for this type of haylage for manufacturing. Bales of the black bale, called “straw bale”, are more expensive than white bales but are very suitable for bedding purposes. Haylage is mainly used to provide cover for grazing animals such as cattle and sheep.
As the name would suggest, haylage bales feature long, thin strips of hay attached to the lower edge of the bale. They are then tied at the top to form a tight coil. As the name would suggest, haylage bales are beneficial for reducing drafty conditions and improving insulation. As well as this, they have a natural tendency to dampen the sound and therefore reduce echo in rooms.
Baling is usually achieved using either round bales or Bale Wrap Plastic. Round bales are loosely shaped bales that are easily assembled and dismantled. They are available in a wide range of sizes. They are most commonly manufactured from wood pulp derived from pine trees. They contain moisture-resistant cellulose fibres and would be ideal for covering or dampening the internal temperature of the silo.
Round bales are typically manufactured for a short period, whereas bulk silage is made continuously over several days in a fermentation process. The length of fermentation can vary depending on various factors such as the volume of material required and the temperature of the fermentation environment. The most popular fermentation method used to manufacture bulk hay, however, is the cold fermentation technique.
Cold fermentation is a method used to manufacture bale wrap or silo hay without losing the weight or structural integrity of the bulk material. Cold fermentation takes place inside a closed metal cylinder. The inside of the cylinder is kept cool through refrigeration, and the temperature is maintained at about minus 10 degrees Celsius. Subsequently, the solid material is poured into the fermentation chamber, and the heat and moisture present to rapidly heat the hay and the straw breaks down while it ferments.
Due to the duration of the fermentation process and the temperature in the fermentation chamber, lactic acid is produced during the process. This gas is commonly known as ‘the friendly gas’ because it provides ample protection for the fermentation process from the effects of oxygen and harmful airborne molecules. The presence of excess lactic acid causes the process to slow down during the later stages of the fermentation process, resulting in less sour silage and hay production. To protect the hay from oxidation during the final stages of production, the cooled bulk silo is placed in an area with direct sunlight.
Plastic straws are often used to cover the hay in the fermentation process. During the fermentation process, excess lactic acid is converted into carbon dioxide and water, which further decreases the amount of hay produced during the fermentation period. The fermentation period can last up to three weeks, depending on the weight of the finished hay. Hay, which is considered a waste product, is collected and transported to local landfills once the fermentation process is complete. Once collected, the hay is washed, sorted, and ready to be transported to a landfill site.
