1, add urea silage In order to increase the crude protein content in silage, 5 kg of urea can be added per ton of silage material. The method of adding is: fully dissolve the urea into water to make an aqueous solution, and evenly spray it on the silage raw material when loading into the cellar. In addition to spraying urea, 3 to 4 kg of urea phosphate can be added to each tonne of silage material, thereby effectively reducing nutrient losses in silage. 2, add trace elements silage To increase the nutritional value of silage, 0.5 g of copper sulfate, 5 g of manganese sulfate, 2 g of zinc sulfate, 1 g of cobalt chloride, 0.1 g of potassium iodide, and 500 g of sodium sulfate may be added per ton of silage material. The method for adding is to thoroughly mix and dissolve the above-mentioned substances in water, spray evenly on the raw materials, and then close the silage. 3, add lactic acid bacteria silage Lactic acid bacteria inoculation can increase the content of lactic acid in silage and increase its nutritional value and utilization. At present, the lactic acid bacteria used for feed silage is mainly Lactobacillus delbrueckii, and the added amount thereof is 0.5 liter of lactic acid bacteria culture per ton of silage material or 450 g of lactic acid bacteria. 4, add formaldehyde silage The addition of formaldehyde to the silage material prevents mildew during the silage process. The addition of 3-5 kg ​​of formaldehyde per ton of silage to ensure that there is no activity of spoilage bacteria in the silage process, so that the loss of dry matter in the feed is reduced by more than 50%, and the digestibility of the feed is increased by 20%. 5, add acid silage Sourcing silage can inhibit feed spoilage. The additive used for acid silage is formic acid. The amount of formic acid is 3 kg per ton of grass forage, and 5 kg per ton of legume forage. However, corn silage is generally not added with formic acid. When using formic acid silage workers should pay attention to avoid direct contact with hands and feet, so as not to burn the skin. 6, semi-dry silage Semi-dry silage is to dry silage materials to semi-dry (moisture content of 45% to 55%) and then chopped, closed silage. The dry matter content of the feed obtained by the semi-dry silage method is about 1 times higher than that of the common silage, and the nutrition is rich and the palatability is good.
