First, the modulation method of fresh leaves
1. Beating: Rinse the collected fresh leaves with clean water, remove the sediment, drain the water, and stir in the appropriate amount of other green feed, such as vegetable leaves, pods, etc., and pulverize directly with the grinder.
2. Silage: Wash the leaves, dry them until they become soft, then pour them into the cylinder barrel or concrete pool, and put them tightly. Then, a layer of plastic film is placed on the leaves, a layer of 7 to 10 cm thick mud is laid on the film, and then a layer of plastic film is overlaid on the film, and the four peripheral mouths are fastened to make it airtight and watertight. It can be taken after ~3 weeks. Stored leaves are yellow-green with acid odor. Any rotten, foul-smelling brown leaf should not be used as feed.
3. Fermentation: Take baking soda (sodium bicarbonate) 1 kilogram and add water to make a paste, then add 15 kilograms of rice bran or bran and mix well, make it into a group and put it down. After 24 hours of stacking, add 50 kg of washed and chopped fresh leaves and 10-15 kg of distiller's grains. Stir well and the water content should be suitable for water droplets. Then, put the cylinder or loading pool, while edge-mounted compaction, filled with mats or old sacks, so that the temperature is maintained at 40 °C ~ 45 °C, stacking fermentation can be used for 48 hours. The well-fermented mixed leaf feed is yellow and has the characteristics of sweet and sour, fragrant and soft, and it has a slight taste of alcohol.
4. Water Storage: Cut up the leaves and layer them into large cylinders or cement pools for compaction. Cover bamboo baskets with water and add fresh water to make the water more than 5 to 8 cm above the leaf surface and keep it. The height can be 4 to 5 days. If the leaves and bran are stored in layers at the same time, the effect is better.
Second, the modulation method of dry leaves
1. Dirty: The leaves that are naturally dropped or collected are dried and beaten into leaf powder, then mixed with water, then loaded into the water-tight cylinder barrel layer by layer, compacted while loading, and filled. Covered with a plastic film, generally 20 to 30 days later, it can be used.
2. To make things worse: Put the leaves in the barrel, add water to soften, and then remove and drain the water. Then cook it in the evening for a night and then pan it the next morning. After the pan, when the material temperature is not hot, mix 20-20 kilograms of fresh lees and 0.5 kilograms of fermented grains per 100 kilograms of steamed material. Mix well and put it in the cylinder barrel. Seal and ferment for 10-15 days.
Third, pay attention (1) Where with bitter, astringent, hemp, spicy and toxic substances such as Li, persimmon, apricot, peach, walnut, bitter buckwheat and other leaves, must first rinse with water, then soaked in water for 1 to 2 days After the elimination of toxicity, feed it.
(2) The fallen leaves harvested with the harvest will prevent mold and deterioration and keep green as much as possible.
(3) When feeding livestock and poultry, the varieties of leaves can not be single, should be a variety of combinations, and fed with other feeds.
