How to use plastic bag silage

The silage of plastic bags can regulate the shortage of feed season and off-season, ensure the supply of green and green feed for off-season of livestock and poultry, and the method is simple and easy, and the cost is low. v4A China Feed Industry Information Network - based on feed, serving animal husbandry

1, plastic bag production: the use of non-toxic polyethylene plastic film, the thickness is required to be more than 0.08 mm, the film is too thin and easy to damage, not suitable for silage. Then make a pocket that is 1.2 meters long and 0.8 meters wide. The seam is required to be airtight, solid and durable. v4A China Feed Industry Information Network - based on feed, serving animal husbandry

2. Harvesting green fodder in a timely manner: Generally, legumes are harvested at the early flowering stage, gramineous plants are harvested at the heading stage, and tuber plants are harvested during the lush period. It must be processed in time after harvesting. To clean the green feed, it can be disinfected once. Then cut into thin sections of about 1 cm long and prepare for silage. At the time of harvesting, it is necessary to keep the raw materials fresh, so as to prevent the green feed from decaying and deteriorating. The moisture content of the prepared silage should be moderate, and the general moisture content should be about 60%. Too dry feed can be added to the green feed with more moisture or sprayed with water to adjust the humidity. The damp feed can be dried to remove some of the water or mixed with some dry green feed to adjust the humidity. v4A China Feed Industry Information Network - based on feed, serving animal husbandry

3. Bagging and sealing: The chopped green fodder is then placed in a plastic bag. First fill the two corners of the bottom of the pocket with a small amount of green fodder, then add the layer of green fodder, and each layer of feed must be pressed tightly to drain the air in the pocket. But you can't use too much force to prevent the plastic bag from being crushed. When it is packed to 80% full, the plastic bag mouth is tightly tied with a rope to make the seal airtight. When the bag is bagged, it is necessary to pay attention to scientific matching. The legume plant feed with higher protein content can be stored together with the gramineous plant feed containing more sugar to improve the nutritional value of the feed. After bagging, the bag of food can be stacked in a dry and ventilated place. Pay attention to frequent inspections to prevent livestock and mice from biting the plastic bag. If the silage bag is damaged, it should be repaired with tape in time. If the damage is serious, it should be replaced with a bag for re-storage. v4A China Feed Industry Information Network - based on feed, serving animal husbandry

4, the use of feed: generally through 20 days of feed is fermented. When accessed, the plastic bag can be opened for identification by sensory. The good silage smells sour, the color is yellowish green, the texture is tight and loose, and the stems and leaves remain intact. If the smell is stinking, it is black, brown, and muddy, it has deteriorated and cannot be eaten by livestock. Good silage can be used for livestock and poultry. Generally, the daily dosage of adult livestock is about 1 kilogram for sheep, 15 kilograms for cattle, and 8 kilograms for horses. Poultry can also be fed in moderation. It should be noted that livestock cannot be fed to silage during pregnancy to prevent abortion. The frozen silage should be used after thawing. v4A China Feed Industry Information Network - based on feed, serving animal husbandry
