This is mainly because the dregs contain antitrypsin, saponin, hemagglutinin and other antinutritional factors, including trypsin inhibiting factor, which can hinder the animal body trypsin digestion and absorption of soy protein, resulting in diarrhea, affecting the growth of poor palatability, difficult to digest, low feed utilization.
After a lot of research by Nongshengle researchers, it is found that after Nongshengle feed fermentation agent treats soybean dregs, it can not only degrade the anti-nutritional factors in soybean dregs, but also improve the palatability as well as improve the nutritional content of soybean dregs, and so on.
Methods of fermentation:
Raw materials: 1000 kilograms of wet dregs,
50 kilograms of bran (cornstarch or chaff, etc.), 2 kilograms of brown sugar. 4 kilograms of Nongshengle feedstuffs fermentation agent. (In accordance with this ratio with can)
Operating steps:
1, first of all, 4 kg of feed fermentation agent with 20 kg of water dilution. Then and 50 kilograms of wheat bran stirred evenly, humidity at about 50% (judgment standards, grab a handful of hand, hard to hold into a pile, hard to hold a little, between the fingers feel wet, but no water dripping down).
2, with about 100 kilograms of water to melt brown sugar (the specific amount of water depends on the dryness and humidity of the dregs).
3, and then mix the bran evenly sprinkled in 1000 kilograms of soybean dregs, once sprinkled, once sprayed with brown sugar water that has been melted, (if there are conditions, you can use a blender to mix, and manually stirred evenly is also perfectly fine).

After mixing well, put it in sealed containers (woven bags, tanks, barrels, fermentation tanks, etc.) to compact and seal the fermentation for 3 to 5 days.
FERMENTATION TEMPERATURE: The ambient temperature is above 15 degrees Celsius for fermentation.
Fermentation time: 3 to 5 days in summer, 7 to 10 days in spring and fall, and more than 20 days in winter.
Success criteria: fruity, clear, wine, sour flavor, soft to the touch, that is, successful fermentation.
Soybean dregs feeding method: feeding fermented material should be fed gradually from less to more, such as the first 5-10% of the amount to feed, to see its adaptation, and then increased to 20%-30%
In addition, if the fermented soybean dregs are more acidic, chickens do not like to eat, you can add 1-2 kilograms of baking soda per 100 kilograms of fermented wet material to neutralize.
Feeding chickens with fermented soybean dregs should pay attention to some of the problems are:
(1) to take the first small amount, slowly increase the principle of the beginning of feeding can be used first 5-10%, and slowly incremental;
(2) in order to achieve and full-price feed basically equivalent to the growth rate, in the preparation of feeds must pay attention to the amount of energy and protein feeds (corn and soybean meal, etc.) additions

loaded, because my family is the use of nongshengle feed fermentation agent treatment of soya bean dregs to feed chickens, it's not bad, I hope to be useful to you Oh.
Wishing you a happy life!
