Raw materials must not be used for rotten degeneration or toxic straw, otherwise they may inhibit the growth of beneficial microbial strains and affect the fermentation effect.
Ventilation stockpiles can not be compacted to avoid air separation, resulting in poor ventilation and affecting the quality of fermentation.
Protect from light in a place where it is exposed to direct sunlight to prevent UV light from killing functional microbes and affecting fermentation.
With various types of straw nutrients and a variety of different odors, the taste of the feed after fermentation also has some differences, a reasonable match with the raw material fermentation will be better, more comprehensive nutrition. (1) Coarse and fine collocation, such as adding about 10-15% of cornmeal in the straw together with fermentation; (2) Collocation of varieties, mixed fermentation of multiple crop straws, such as corn stalks and wheat stalks, etc., so that nutrition is more comprehensive, Better results. (3) feeding collocation. Fermented straw feeds should be fed together with the full-price feed mix in the required proportions. Cows, sheep, ducks, geese, and empty sows can be fed directly. Pigs and chickens should be fed in proportion.
The weight of each fermentation straw should not be less than 15 kg. The amount of straw is not good for heating and it is difficult to ensure the quality of fermentation.
Straw fermented straw fermented fermented straw feed is best fed now, it should not be stored for a long time, the general storage should not be more than two days, generally should be based on two days or so of the amount of feed, accounting to determine the amount of raw materials for fermentation. If the storage time is more than two days, an anaerobic storage method should be adopted to cool the fermented material and seal it for storage. For small-scale farmers with three or five pigs, it is best to mix the raw materials, such as corn flour, which should be fed, and the straw feed, and ferment them together. After the fermentation, mix the concentrates and feed them together. In this way, it not only promotes feed conversion and absorption, but also solves the problem of current feed feeding.
