Bean dregs is a by-product left over from soybean processing and production of soy products. It is measured that the crude protein content of fresh bean dregs is about 8.0%, and that of dried bean dregs is 27.7% crude protein and 6.0% crude fiber. , the nutritional content is higher than that of many residues. At present, using microecological technical measures to ferment bean dregs and then feeding them to pigs has achieved obvious economic benefits.

1 Traditional feeding method

Bean okara contains a kind of antitrypsin, which can hinder the digestion and absorption of bean protein by trypsin in pigs, causing diarrhea and affecting growth. Bean dregs cannot be fed directly raw. The traditional method requires heating the bean dregs and boiling them for more than 15 minutes to destroy the antitrypsin in them, so that the protein in the feed can be fully utilized. However, this method requires fresh processing and feeding. The cooked bean dregs The storage time is short and labor-consuming.

2 Micro-ecological technical measures

After fermentation with Lebeifon (biological feed starter), not only does it not need to be cooked, but it also has better feeding effects. Lebeifeng (biological feed starter) combines the comprehensive functions of beneficial microorganisms, probiotics, enzyme preparations, deodorants, animal health products, growth promoters, hypnotics, food-promoting sweeteners, and Chinese herbal additives. Each gram contains The effective number of active bacteria reaches more than 12 billion, and the vitality is super strong. The main ingredients of Lebeifeng (biological feed starter) include lactic acid bacteria, Bacillus, fungi, complex enzyme preparations, auxiliaries, etc., which can convert most crop straw, residue, bran and other roughage in a very short time Decompose into high-quality feed that is easily digested and absorbed by monogastric animals and non-monogastric animals.

This fermentation product has the following advantages.

① The increased content of beneficial bacteria can inhibit the growth of harmful bacteria and can be stored for a long time, but it is best to use it within 1 month.

②Contains a large amount of beneficial bacteria, which can decompose and transform the antitrypsin in bean dregs and improve the intestinal microecological environment of pigs. No matter whether piglets or piglets are fed, they will not cause diarrhea.

③ Breaks the cell structure of crude fiber and improves the conversion rate of nutrients. It is especially suitable for fattening pigs and lactating sows. Sows should not use it too much during late pregnancy, otherwise the sow will be too fat and affect farrowing.

④It has a special sweet and sour taste and good palatability. Containing about 5% alcohol content, the pigs will sleep quietly after eating, their fur will be bright and ruddy, and they will grow quickly.
