Soybean residue is a by-product in the process of eating soybean milk or tofu, and the annual output of soybean residue is very large all over the world. China is the birthplace of tofu consumption, which has a long history. The consumption and sales of tofu are relatively large, and the corresponding output of bean dregs is also very large. With the development of science and the progress of human cultural quality, people began to re-understand bean dregs from the perspective of nutrition. Facts have proved that a large part of nutrients in soybeans remain in bean dregs. Ordinary bean dregs contain 85% water, 3.0% protein, 0.5% fat and 8.0% carbohydrates (cellulose, polysaccharide, etc. ), in addition to containing minerals such as calcium, phosphorus and iron, it is rich in nutritional value and low in price, and can be used as feed for raising geese. However, there are many harmful bacteria, parasites and indigestible components in raw bean dregs, and direct feeding will cause some harm to geese, such as diarrhea and bloating. If it can be used reasonably, it can bring considerable economic benefits to users. The starter can fully ferment the bean dregs, which can not only reduce the feeding cost, but also detoxify the bean dregs.

How to raise geese with bean dregs

When weighing fermented bean curd residue, if the proportion of bean curd residue is 30%, take 70% of other feeds in the above table. Because the bean dregs are wet and the water content is about 60%, the proportion weight should be multiplied by a little more than 2 times. Or the complete feed or the feed formula we introduced earlier plus the proportion of fermented bean dregs can be used, that is, the complete feed or self-made feed is prepared according to the proportion of 70% and fermented bean dregs 30%, and so on.

The method of feeding geese with fermented bean dregs: it can be directly mixed into the complete feed, that is, a small amount of fermented bean dregs is directly used in the complete feed on the market.

1, 0 ~ 4 weeks old: 80% complete feed, 20% fermented bean dregs, 4% premix 0.8%. Of course, when feeding fermented bean dregs, it should be domesticated at 10% first, and then gradually increased to 20%. If the goose is still adapted, it can continue to increase the dose to reduce the cost.

2.4 ~ 10 weeks old: 70% complete feed, 30% fermented bean dregs, 1.2% 4% premix. If the goose is still adapted, it can continue to increase the dose to reduce the cost.

3. 10 weeks old or older: 60% complete feed, 35% fermented bean dregs, 5% corn flour, 4% premix 1.4%. If the goose is still adapted, it can continue to increase the dose to reduce the cost.

Matters needing attention in feeding geese with bean dregs

1, moldy and deteriorated raw materials or raw materials with peculiar smell cannot be used as fermentation raw materials. If the fermented product is moldy or stinky due to improper preservation, it cannot be used to feed animals.

2, when stacked, the pool should be sealed, but not tight.

3. When feeding in containers or bags, the containers should be sealed immediately and should not be exposed for too long, so as to avoid pollution, corruption and deterioration.

4. Store in a cool and dry place. If the fermented material is to be stored for a long time, it should be sealed and compacted, and the air in the packaging bag should be exhausted as much as possible. This can not only be stored for a long time, but also degrade during storage. After a long time, the digestion and absorption rate will be better and the nutrition will be better. It can also be dried and stored in a jar.

Benefits of fermented bean dregs:

1, nutritional components of bean dregs

Bean dregs is a kind of dietary fiber and protein source with development value, which is rich in minerals and trace elements and has high nutritional value. It is a high-quality and cheap food resource. Soybean dregs are rich in dietary fiber, of which cellulose accounts for more than half of dry matter, and cellulose is a functional component with health care function in food. Soybean residue also contains high-quality protein, and its amino acid ratio is close to the reference value proposed by FAO.

2, bean dregs need to be treated

Soybean dregs have high fiber content, large fiber particles, rough taste, difficult absorption of anti-nutritional factors and strong bean dregs smell, so it is difficult to develop and utilize soybean dregs. These problems need to be solved by using Haowangnong feed starter after fermentation. Bean dregs can't be fed directly, so it needs fermentation, softening and deodorization to prevent three anti-nutritional factors in bean dregs from hindering the digestion and absorption of protein by trypsin in the body, causing diarrhea and affecting growth.

3. Nutritional value of fermented bean dregs

After bean dregs are fermented by feed starter, the crude protein can be improved a lot, especially the digestible protein rate in crude protein is increased by 1/3, and the crude fiber is decreased by more than 1/3, which fully shows the fermentation effect of fermentation bacteria on goose feed containing bean dregs. It can also improve the energy value, make geese love to eat more, promote appetite and enhance the secretion of digestive juice. Haowangnong feed starter is a carrier of probiotics, which contains a large number of beneficial microorganisms and acidulants such as lactic acid, and vitamins are greatly increased, especially B vitamins are often increased several times. If not fermented, bean dregs are easy to deteriorate and difficult to preserve, and geese are prone to diarrhea and diarrhea after eating, which affects their health and growth rate.

4. Benefits of fermented bean dregs

(1) Cost saving promotes growth.

(2) Long storage time.

(3) Prevent diarrhea and abdominal distension.
