For the formation of silage bales in agro stretch film, a farmer who is already packing feed in bales wrapped with a bale net wrap needs only to add a wrapper directly with a film stretch.And, of course, the stretch film itself, which is already wrapped over the hay net.
The quality of silage in silage bags is higher due to less loss of leaves and less exposure to weather conditions. On average, losses reach 5 %, provided that the technology is followed correctly and the bales are regularly checked for punctures, followed by repair with adhesive tape. At the same time, the loss of hay stored outdoors can reach 20 to 50 %.
The most important advantage of silage bags is the possibility of packaging feed stuff without waiting for drying, that is, with a grass moisture content of 45 to 55 %.Accordingly, there is no need for a long and risky wait for hay to dry, which is necessary when packing in a bale net wrap with twine tying. This is a big advantage in the rainy season. The feed stuff itself also turns out to be more energetically valuable. You can verify this with an example:
The ideal time to wrap feed stuff in stretch film is between 2 hours and 24 hours after mowing. Then the feed stuff will contain the greatest amount of acids during the subsequent fermentation of the silage. After a day, the quality of the herbs decreases.
An oxygen-free environment is essential for the production of good silage. Oxygen, which has already entered the bale during packaging, is gradually removed due to the respiration of plant cells.
Accordingly, all that the farmer needs in the future is to ensure that no new oxygen enters the silage bales, that is, to monitor the absence of punctures.
During the maturation of silage inside the silage bale, the number of beneficial lactic bacteria increases, and the number of harmful ones decreases due to the lack of oxygen. All this is possible at humidity up to 55-60%. Humidity above 60% or heavy soiling with mud and manure can lead to clostridial fermentation and the formation of ammonia and butyric acid, often reported by a characteristic malodor.
The ingress of oxygen into the wrapper contributes to an increase in heat treatment. As a result, vegetable sugars are converted into CO2, which leads to a decrease in the digestible nutrients in the feed stuff.
Advice! 4 layers of stretch film with 50% overlap are recommended after the feed is wrapped in the bale net wrap. Or at least 6-7 layers with an overlap of 12-18%.
One of the obligatory stages of wrapping feed stuff in stretch film is wrapping it in round bales wrapped in hay netting. If you are looking for quality bale net, please contact us, one of the best bale net wrap manufacturers in the world.
