Method of fermenting feed with Nongshengle feed fermentation liquid: (No matter which feed is fermented, the method and principle are the same)
Crushing: coarse and hard materials are crushed to 1 ~ 5 mm, and fine and soft materials are crushed to 1 ~ 2 cm.
Adding starter: 400 kg green feed needs 65,438+0 kg Nong Le Sheng feed fermentation broth, 300 kg roughage needs 65,438+0 kg Nong Le Sheng feed fermentation broth, 200 kg virus-free feed needs 65,438+0 kg Nong Le Sheng feed fermentation broth, and 200 kg dung feed needs 65,438+0 kg Nong Le Sheng feed fermentation broth.
Moisture regulation: the moisture content of fermented material should be controlled at about 60% (green feed can be controlled at about 70%), that is, it can be dispersed when it is held in hand without dripping. If the water content is too large, dry materials such as bran can be added to adjust; If the water content is too small, you can directly add water to adjust it.
Fermentation requirements: sealed and compacted.
Fermentation temperature: fermentation can be carried out when the ambient temperature is above 15 degrees.
Fermentation time: 3 ~ 5 days in summer, 7 ~ 10 days in spring and autumn, and more than 20 days in winter.
Success criteria: fruity, alkyd, soft to the touch, that is, successful fermentation.
Feeding method: Feed the fermented materials gradually from less to more, generally starting from 5%, and the maximum addition is 30%.
